| - | ==== April 28, 2015 ==== | + | |
| - | Joint meeting with ETSI NFV REL team. | + | |
| - | Agenda: | + | |
| - | - Identify Purpose of the call | + | |
| - | * Collaboration kick-off | + | |
| - | - NFV REL: | + | |
| - | * Project Overview | + | |
| - | * NFV upgrade | + | |
| - | * Active monitoring and failure detection | + | |
| - | - OPNFV Doctor: | + | |
| - | * Project Overview | + | |
| - | * Use cases | + | |
| - | - Collaboration methodology discussion | + | |
| - | - Wrap-up | + | |
| - | + | ||
| - | Minutes: | + | |
| - | - Purpose | + | |
| - | * Ryota: know each other; see how to work together; further technology discussion needed at later stage | + | |
| - | * Markus Schoeller (NEC): no IPR declarations today, today only exchange of public information | + | |
| - | * policies how to work together w.r.t IPR etc should be defined for later work | + | |
| - | * Gurpreet: high-level of Doctor project; fault-detection and management; what are use cases of Doctor? | + | |
| - | - NFV REL introduction (Markus Schoeller) | + | |
| - | - Project overview: see ETSI/NFVREL(14)000200) | + | |
| - | * dedicated reliability project | + | |
| - | * Ryota: target size / number of applications? | + | |
| - | * Tommy: which work items focus on VIM part? indirectly addressed in monitoring and failure detection. scalabilty per se has some impact on VIM | + | |
| - | * Tommy: this means "monitoring and failure detection" would be the main crossing point with Doctor? so far yes, but in next meeting new WIs may be created | + | |
| - | - NFV software upgrade mechanism (Stefan Arntzen - Huawei) | + | |
| - | * different to traditional upgrades: "old traffic" can still go to "old software version", whereas new traffic/connections can go to the new s/w version in parallel (this is enabled by virtualization); no hard switchover needed; old system/version is still running and it can be switched back in case of issues with the new version | + | |
| - | * assumption is that this can be done stateless (otherwise it would be more complex) | + | |
| - | - Active monitoring for NFV (Gurpreet) | + | |
| - | * Alistair Scott: interested in passive monitoring; where as attachment points for passive monitoring? REL has not looked in passive monitoring for NFV | + | |
| - | * Gurpreet: identify use cases where current implementation has gaps | + | |
| - | - OPNFV Doctor | + | |
| - | * Stefan: plan to use OpenStack components? | + | |
| - | * Ryota: we are not only focusing OpenStack, but open source in general | + | |
| - | * Tommy: but OpenStack is the primary s/w used in OPNFV | + | |
| - | * Gurpreet: work flow for upstream community? | + | |
| - | * Ryota: define requirements, gap analysis, provide blueprints, but no coding in Doctor project | + | |
| - | - Next action: | + | |
| - | * arrange meeting in the next NFV event | + | |
| - | * keep in touch | + | |

| - | Minutes: | + | |
| - | - Input from Swfastpathmetrics team | + | |
| - | * current integration plan is https://collectd.org/ and also ceilometer | + | |
| - | * Revisit the scope of the NIC to makes sure that we can collect VF stats. | + | |
| - | * TBD | + | |
| - | * Can the NIC report VF/PF stats capabilities? Investigate: Maryam | + | |
| - | * I’ve been looking into this for Intel® 82599 10 GbE Controller, and this might be possible through a level of indirection by checking what VFs are enabled. It’s not exactly what’s being asked, but if you know what knew a VF was enabled then you’d know what stats are also available. | + | |
| - | * BTW: Stats can then be retrieved then per VF for Niantic: | + | |
| - | * VF Good Packets Received Count | + | |
| - | * VF Good Packets Transmitted Count | + | |
| - | * VF Good Octets Received Count Low | + | |
| - | * VF Good Octets Received Count High | + | |
| - | * VF Good Octets Transmitted Count | + | |
| - | * VF Good Octets Transmitted Count | + | |
| - | * VF Multicast Packets Received Count | + | |
| - | * But then error stats are still shared. | + | |
| - | * Open Maryam is looking into is if we knew the Queues that were assigned to a VF could we use Queue Packets Received Drop Count (QPRDC) to retrieve the dropped packets for a VF? | + | |
| - | * Maryam in the process of writing a DPDK app that runs as a secondary process on the host and is capable of reading the stats, which can then be parsed by a script. | + | |
| - | * Still in progress | + | |

| - | - Input from Swfastpathmetrics team: | + | |
| - | * https://collectd.org/ | + | |
| - | * The following set of statistics are those that are collected explicitly for the physical NIC (Intel 10G Niantic) | + | |
| - | * Physical Function (PF) Summed up/total ReceiveErrors/Drop Statistics Reported (note** these are per Port) | + | |
| - | * PF Packet drop: Sum of ( all drop registers we list)excluding error register | + | |
| - | * PF Packet errors: Sum of ( all error registers we list)excluding drop registers | + | |
| - | * PF PHY errors: Sum of (all PHY errors we list) | + | |
| - | * PF General errors: Sum of (all other rx/tx errors regs welist) | + | |
| - | * PF Missed RX: A missed packet is a packet that was correctly received by the NIC but because it was out of descriptors and internal memory, the packet had to be dropped by the NIC itself | + | |
| - | * Physical Function (PF) IndividualReceive Errors/Drop Statistics Reported | + | |
| - | * Illegal Byte Error Count: Counts the number of receive packetswith illegal bytes errors (such as there is an illegal symbol in the packet). | + | |
| - | * Error Byte Count: Counts the number of receive packetswith error bytes (such as there is an error symbol in the packet). | + | |
| - | * Rx Missed Packets Count | + | |
| - | * MAC Local Fault Count : Number of faults in the local MAC. | + | |
| - | * MAC Local Fault Count: Number of faults in the remote MAC. | + | |
| - | * Receive Length Error Count: Number of packets with receive length errors. A length error occurs if an incoming packet length field in the MACheader doesn't match the packet length. | + | |
| - | * Receive Undersize Count:. This register counts the number of received frames that are shorter than minimum size (64bytes from <Destination Address> through <CRC>, inclusively), andhad a valid CRC. | + | |
| - | * Receive Fragment Count: Number of receive fragment errors (frame shorter than 64 bytes from <Destination Address> through <CRC>,inclusively) that have bad CRC (this is slightly different from the ReceiveUndersize Count register) | + | |
| - | * Receive Oversize Count: This register counts the number of received frames that are longer than maximum size as defined by MAXFRS.MFS (from <Destination Address> through <CRC>,inclusively) and have valid CRC. | + | |
| - | * Receive Jabber Count: Number of receive jabber errors. This register counts the number of received packets that are greater than maximum size and have bad CRC (this is slightly different from the Receive OversizeCount register). The packets length is counted from <Destination Address>through <CRC>, inclusively. | + | |
| - | * Management Packets Dropped Count: Number of management packets dropped.This register counts the total number of packets received that pass the management filters and then are dropped because the management receive FIFO is full. Management packets include any packet directed to the manageability console (such as RMCP and ARP packets). | + | |
| - | * MAC Short Packet Discard Count: Number of MAC short packet discard packets received. | + | |
| - | * XSUM Error Count: Number of receive IPv4, TCP, UDP or SCTPXSUM errors. | + | |
| - | * FC CRC Error Count: Count the number of packets with goodEthernet CRC and bad FC CRC | + | |
| - | * FCoE Rx Packets Dropped Count: Number of Rx packets dropped due to lack of descriptors. | + | |
| - | * And the final thing we measure is packet latency through DPDK. | + | |

| - | Minutes: | + | |
| - | * Recap of last weeks BP meeting (Thursday) | + | |
| - | * Ryota had presented; request was to use the template; more details needed, but general approach is okay | + | |
| - | * Bryan has raised issue that more discussion on notification on NB I/F interface is needed | + | |
| - | * important which protocol and data structure is used | + | |
| - | * Proposal of Doctor should be aligned with other projects | + | |
| - | * Ashiq: does anyone have experience in writing BPs -> Tomi: using the template it was straightforward | + | |
| - | * proposal to find someone with experience. Ryota already has some experience. | + | |
| - | * Ryota: problem is who could review our BPs. we need to socialize with community. Ryota has some channels he can use for this. | + | |
| - | * it is not clear if we need TSC approval for submitting the BPs; at least we should align at OPNFV level | + | |
| - | * Ashiq: it is important people join the meetings, e.g. the BP meeting, the individual BP meetings, socialize the BPs in the OPNFV community (by discussing it on the mailing list) | + | |
| - | * Tomi: proposal to send mail to tech-discuss asking for any objections within few days, then upload | + | |
| - | * Ryota: we need this window to also review other contributions | + | |
| - | * Ashiq: already upload the BPs and revise it in case needed | + | |

| - | * ACTION: perform Doctor internal review by end of this week. | + | |
| - | * Stable draft will be provided to two weeks OPNFV-wide review on Monday March 30th | + | |
| - | * Ashiq: architecture with 4 building blocks. Inspector filters some fault information. In Notifier is a policy to also filter which fault informations to send or not. | + | |
| - | * why do you enable the filtering in both Inspector and Notifier? Ryota: different kind of filters. in OpenStack all alarms from Controller will be emitted, thus we need to have policy to filter. | + | |
| - | * Ashiq: Inspector is filtering physical faults. notifier is filtering faults on virtual resource level. Correct? | + | |
| - | * Document Review | + | |
| - | * Others: | + | |
| - | * join HA meetings time-by-time to monitor their progress; check status of their BPs and offer help. | + | |

| - | * Two alternative ways to implement it: | + | |
| - | * New Nova API -> might not be accepted easily | + | |
| - | * offline mail discussion ongoing | + | |
| - | * Use Pacemaker servicegroup driver -> might not address all requirements of Doctor | + | |
| - | * TL: Is there some possibility to ask Nova to update its state? TJ: currently doing some testing on this; also to measure the reaction times | + | |
| - | * TL: servicegroup is within one cluster. there is also a pacemaker remote, but might be slow | + | |

| - | Requirement project round table @ Prague Hackfest | + | |
| - | + | ||
| - | Participants: Ryota (NEC), Gerald (DOCOMO), Bertrand (DOCOMO), Ashiq (DOCOMO), Tomi (Nokia), Tommy (Ericsson), Carlos (NEC), Gianluca Verin (Athonet) Daniele Munaretto (Athonet), Sharon (ConteXtream), Christopher (Dorado Software), Russell (Red Hat), Frank Baudin (Qosmos), Chaoyi (Huawei), Al Morton (AT&T), Xiaolong (Orange), (Oracle), Randy Levensalor (CableLabs) ... | + | |

| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * Use case 1 "Fault management" | + | |
| - | * Main interest: northbound I/F | + | |
| - | * Reaction of VNFM is out of scope | + | |
| - | * VM (compute resouces) is the first focus, storage and network resources will follow at later stage | + | |
| - | * Fault monitoring: plugable architecture is needed to catch different (critical) faults in NFVI to enable use of different monitoring tools. Predictor (fault prediction) may also be one input. | + | |
| - | * see also https://wiki.opnfv.org/doctor/faults | + | |
| - | * 4 functional blocks: | + | |
| - | * controller (e.g. Nova), monitor (e.g. Nagios, Zabbix), notifier (e.g. re-use Ceilometer), inspector (fault aggregation etc) | + | |
| - | * VM state in resource map, e.g. "fault", "recovery", "maintenance" (more than just a heartbeat) | + | |
| - | * Question of whether other OpenStack components (e.g. Cinder, Glance, etc) can report events/faults | + | |
| - | * What is the timescale to receive such fault notification? this would be helpful for the motivation in the blueprints. Telco nodes: i.e. less than 1s, switch to ACT-SBY as soon as possible. | + | |
| - | * Preference is event based events, not polling. should be configurable. | + | |
| - | * Telco use case would have few hundreds of nodes, not thousands of nodes. | + | |
| - | * Demo 1 (using default Ceilometer) takes approximately 65 seconds to notify the fault (90 seconds total including spawning new VM), while demo 2 only takes <= 1 second (26 seconds total) | + | |
| - | * Pacemaker is running at application layer; different scope. | + | |

| - | * Doctor: | + | |
| - | * detecting fault from resource pool, HW, hypervisor, OS | + | |
| - | * table in Openstack mapping between VM and manager | + | |
| - | * Fault prediction (Predictor, Requirement project; https://wiki.opnfv.org/requirements_projects/data_collection_of_failure_prediction) | + | |
| - | * predict the will be fault in (near) future | + | |
| - | * overlap, but not conflict | + | |
| - | * FathPathMetrics (Development project; https://wiki.opnfv.org/collaborative_development_projects/opnfv_telco_kpi_monitoring) | + | |
| - | * SW fastpath implementation -> interfaces to DPDK | + | |
| - | * consume statistics and counters | + | |
| - | * information goes to VNF, it does not go to OpenStack (in that sense there is no overlap) | + | |
| - | * HA (Requirement project; https://wiki.opnfv.org/high_availability_for_opnfv) | + | |
| - | * quick response. time-critical. | + | |
| - | * very short response for fault detection and resolve | + | |
| - | * people from HA project really work on HA today, have a lot of knowledge on it | + | |
| - | * Identify Overlap: | + | |
| - | * NB I/F | + | |
| - | * Doctor is also requiring fast reaction. objective with HA is similar. | + | |
| - | * HA has more use cases and may send more information on the northbound I/F. VNFM should be informed about changes. | + | |
| - | * Doctor objective is to design a NB I/F. | + | |
| - | * Does HA already have flows available? | + | |
| - | * HA is focusing on application level. Reaction should be as fast as possible. Including the VNFM may slow down the progress. | + | |
| - | * In Doctor we will follow the path through VNFM. | + | |
| - | * In ETSI we have lifecycle mgmt, where VNFM is responsible for the lifecylce | + | |
| - | * There are certain information the VNFM doesn't know about. In Doctor we call it "consumer". | + | |
| - | * Proposal to do use case analysis for HA. Which use cases may require the VNFM to be involved? "Doctors" will have a look at HA use cases. | + | |
| - | * How is the entity to resolve race conditions? Some entity in the "north". | + | |
| - | * What about a shared fault collection/detection entity instead of collecting the same information 3 times? | + | |
| - | * Predictor could also notify immediate failures to Doctor. | + | |
| - | * Security issues are not addressed in Doctor. Currently assuming a single operator, where policies ensure who can talk to who. | + | |
| - | * In Doctor we do not look at application faults, only NFVI faults. | + | |
| - | * Huawei: we use Heat to do HA. if one VM died and Heat will find Scaling Group less than 2, it will start a new VM. This may take more than 60s, we need to find something faster for HA. Heat doesn't find error in the applications. | + | |
| - | * Failure detection time is an issue across all projects. | + | |
| - | * Which metrics of fastpath would Doctor be interested in? need to check in detail. Action Item to send metrics to Doctor. | + | |
| - | * Hypervisor may detect failure of VM and take action. | + | |
| - | * Other failures: VM is using heartbeat. it will e.g. reboot after not receiving a heartbeat for 7s. | + | |
| - | * Doctor: if VIM takes action on its own it may conflict the ACT-SBY configuration at the consumer side. this is why the consumer should be involved. | + | |
| - | * Which project would address ping-pong issue that may arise? | + | |
| - | * We need subscription mechanism including filter (which alarms to be notified about). Mapping VM-PM-VNFM can be recorded during the instantiation. | + | |
| - | * Relationship between Doctor and Copper: | + | |
| - | * policy defines e.g. when VIM can expose its interface | + | |
| - | * When to inform a fault, whom to inform etc is all a kind of policy. | + | |
| - | * Copper has both pro-active and reactive deployment of policies. In reactive case, there may be conflict when both Copper and Doctor receive the policies. | + | |
| - | * Wrapup: | + | |
| - | * Overlap in fault management | + | |
| - | * FastPath: monitor traffic metrics; Doctor will need some of the metrics in the VIM. plan to do regular meetings. | + | |
| - | * HA: large project with wider scope than Doctor, different use cases. direct flow (to be faster). task to check each others NB I/F in order not to block each other. | + | |

| - | + | ||
| - | Agenda: | + | |
| - | + | ||
| - | * Timeline - Ryota | + | |
| - | * This proposal has close relation: data collection of failure prediction | + | |
| - | * https://wiki.opnfv.org/requirements_projects/data_collection_of_failure_prediction | + | |
| - | * Both collect host data? | + | |
| - | * Doctor to receive faults from predictor. | + | |
| - | * Is this feasible. Doctor can be configured to gather also similar data and make graphs. | + | |
| - | * Praque meetup time. | + | |
| - | * Implementation plan: review comments by Tomi in last week's minutes | + | |
| - | * Wiki Updates to follow BGS format - Ryota | + | |
| - | * Doctor team participation in the OpenStack Summit Vancouver - Carlos | + | |
| - | * Should we aim at proposing a talk session? | + | |
| - | * Deadline is February 9 | + | |
| - | * http://www.openstack.org/summit/vancouver-2015/call-for-speakers/ | + | |
| - | * Weekly meeting time - Ryota ? | + | |
| - | * There is conflict with ETSI IFA meeting. | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * Participants: Carlos Goncalves, Don Clarke, Ryota Minu, Tomi Juvonen, Yifei Xue, Al Morton, Bertrand Souville, Gerald Kunzmann, Manuel Rebellon, Ojus K. Parikh, Ashiq Khan, Pasi, Paul French, Charlie Hale, | + | |
| - | * Ryota presents a refreshed Timeline | + | |
| - | * https://etherpad.opnfv.org/p/doctor | + | |
| - | * Initial draft of requirement document should be ready before the Hackfest 23-24 Feb in Prague | + | |
| - | * Ashiq asks about task allocation. See: https://etherpad.opnfv.org/p/doctor | + | |
| - | * Target architecture is OpenStack; Implementation plan is on how this will be realized in upstream projects, e.g. interfaces. | + | |
| - | * one proposal is using Zabbix. all is already there. | + | |
| - | * Predictor project: | + | |
| - | * still in proposal phase. we should keep eye on it. it has relation to Doctor | + | |
| - | * Implementation plan: | + | |
| - | * for evacuation we should stay implementation independent, not OpenDayLight or Neutron (they may use it in the actual testbed, but we should restrict Doctor to the interfaces definition) | + | |
| - | * it is not intended to use Ceilometer, but a similar service. | + | |
| - | * Agreement to use Zabbix for the GapAnalysis. | + | |
| - | * Doctor will have its own RestAPI as wrapper abstracting the in use monitoring solution underneath (e.g. Zabbix) | + | |
| - | * it is necessary to be able to isolate a faulty machine, such that new VMs are not started on this machine. | + | |
| - | * different ways/workflows for recovery; we should start by implementing a few sample workflows | + | |
| - | * e.g. switch to active hot standby VM, then instantiate a new hot standby instance (this is a Doctor requirement) | + | |
| - | * evacuation (if time allows) vs active hot standby (immediate action) | + | |
| - | *VNFM is deciding about the best action (this is out of scope of Doctor; Doctor only specifies NB I/F) | + | |
| - | * we need to get into more details for this plan. discussion should go via email to make progress before next meeting | + | |
| - | * Hackfest | + | |
| - | * Take to the hackfest what we have, i.e. if we "only" have one implementation plan so far let's use this. | + | |
| - | * https://etherpad.opnfv.org/p/HackfestFeb23 | + | |
| - | * Doctor is planned for Tuesday. Also other requirement projects will be discussed on Tuesday. | + | |
| - | * Ryota did cleanup of Doctor Wiki page | + | |
| - | * Doctor team participation in the OpenStack Summit Vancouver? | + | |
| - | * related topics. | + | |
| - | * most important blueprints should be ready by May and could be presented there | + | |
| - | * Proposal: Talk on a more general topic including Doctor requirements | + | |
| - | * Carlos will look into it | + | |
| - | * Meeting time -> via email | + | |
| - | + | ||
| - | ==== Jan 26, 2015 ==== | + | |
| - | + | ||
| - | Agenda: | + | |
| - | + | ||
| - | * Discuss maintenance use case - Tommy | + | |
| - | * Implementation outside Nova - Tomi | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * Timeline milestone planning | + | |
| - | * Soft schedule for Fault Table, set 1 milestone end of Jan | + | |
| - | * Requirement Document should be finished by Mar 15 ? - No | + | |
| - | * Ashiq suggested doc should be finished by end of February | + | |
| - | * Set some milestone on Hackfest at Prague | + | |
| - | * First draft | + | |
| - | * TODO(Ryota): create wiki page | + | |
| - | * Discuss maintenance use case - Tommy | + | |
| - | * https://etherpad.opnfv.org/p/doctor_requirement | + | |
| - | * Cloud User (NFVO/VNFM) can express allowed operations to VIM by labeling VM some tag e.g. allow-live-migration | + | |
| - | * We don't need realtime notification for maintenance | + | |
| - | * Implementation outside Nova - Tomi | + | |
| - | * https://wiki.opnfv.org/_media/doctor-opnfv-proposal.pptx | + | |
| - | * FYI: http://blog.russellbryant.net/2014/10/15/openstack-instance-ha-proposal/ | + | |
| - | * Network resources? | + | |
| - | * Evacuation will move the network also regardless it being OpenDaylight or Neutron. | + | |
| - | * We are trying to tackle step-by-step, first focusing on Nova. | + | |
| - | * Ceilometer approch seems to be good rather than using metadata on Nova | + | |
| - | * What is the relation to Nova metadata? Ceilometer is therrible for FM. It uses polling, and suits for PM. It would be extra step causing delay. It makes a lot of network traffic. Database consumes a lot of memory. | + | |
| - | * Should we kick poweroff the host by Doctor? | + | |
| - | * One needs to fence host by powering off by shutdown trough OS (or Nova) or if reachable only with IPMI, then trough that. In some case host can be rebooted as recovery, but in most cases it is faulty and needs to be moved to disabled aggrigate or mark for maintenance. If one do not reach host at all, the evacuation trough Nova will anyhow isolate host as everything will be moved to other host (network, disk). | + | |

| - | + | ||
| - | Agenda: | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * Fault table: https://wiki.opnfv.org/doctor/faults | + | |
| - | * Action: check and revise / update / extend | + | |
| - | * Some faults are specific to a certain HW other are more general | + | |
| - | * We should try to come up with a high level description of common faults | + | |
| - | * Proposal not to go to such level of detail. | + | |
| - | * Keep one fault table and use the current fault table for study of the scope of Doctor | + | |
| - | * Are there other faults that cannot be detected by SNMP and Zabbix_agent? | + | |
| - | * We need a tool in Doctor that can retrieve such alarms. Should this tool be integrated with OpenStack or be independent? Should be kept open; | + | |
| - | * different tools may be used given clear interfaces are specified | + | |
| - | * Monasca: https://wiki.openstack.org/wiki/Monasca OpenStack project for monitoring of faults; still in its early days | + | |
| - | * ETSI meeting in Prague: proposal to meet there | + | |
| - | * https://etherpad.opnfv.org/p/HackfestFeb23 | + | |
| - | * Action: update your participation on that EtherPad page | + | |
| - | * Doctor "working page": https://etherpad.opnfv.org/p/doctor_gap_analysis | + | |
| - | * Action: edit this page for ongoing work on the gap analysis | + | |
| - | * Doctor wiki page updated | + | |
| - | * Use cases moved to extra page: https://wiki.opnfv.org/doctor/use_cases | + | |
| - | * Timeplan: | + | |
| - | * Action: Ryota to prepare a timeplan/timeline | + | |
| - | * Timeplan can be checked in each week's meeting | + | |
| - | * seems we are behind initial time plan (see https://wiki.opnfv.org/_media/doctor_141208.pdf slide 11) | + | |

| - | ==== Dec 22, 2014 ==== | + | |
| - | + | ||
| - | Agenda: | + | |
| - | + | ||
| - | * work item updates | + | |
| - | * Fault table | + | |
| - | * GAP analysis template | + | |
| - | * Wiki pages | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * Work item updates | + | |
| - | * Fault table | + | |
| - | * Status: waiting Palani's initial commit | + | |
| - | * Tomi also made initial list of faults. | + | |
| - | * TODO(Tomi): Open new wiki page to share the fault list | + | |
| - | * GAP analysis template | + | |
| - | * Ryota explained GAP analysis template drafted on https://etherpad.opnfv.org/p/doctor_requirement | + | |
| - | * TODO(Ryota): Open new etherpad page for Gap Analysis with the template | + | |
| - | * Wiki pages | + | |
| - | * Our plan for wiki/doc structure seems to be OK, cause there was no question and objection in the past week. | + | |
| - | * TODO(Ryota): Update wiki pages | + | |
| - | * Fault notification at the Northbound I/F | + | |
| - | * Critical faults | + | |
| - | * It was agreed that we should characterize faults as critical ornon-critical when reporting to VNFs. | + | |
| - | * We must report all critical faults northbound. We may report some of the non-critical faults, need further study. | + | |
| - | * Fault aggregation | + | |
| - | * Discussed whether toaggregate different alarms and faults before notifying via northbound interfaceto VNFs. | + | |
| - | * General agreement that there should be some level of aggregation, butneed to figure out what events need to be aggregated. | + | |
| - | * Some suggested that VNFs should be notified only if the faults are urgent. | + | |
| - | * Notifying data center operations folks about hardware faults is something that seems to be out of scope for this project. Tomi: I think they need the information and there should not be a duplicate mechanism to detect faults to be able to make HW maintenance operations. Surely they will not need the notification that we would send to VNFM, but the actual alarm information we are gathering to make those notifications. Anyhow I agree that this is not in our scope and tools like Zabbix that we could use here can easily be configured then for this also in case HW owner is interested. | + | |
| - | * Why should warnings be sent to VNFs (such as cpu temp rising but notcritical yet)? VNFs might want to take action such as setup/sync hot standbyand this could take some time. | + | |
| - | * Are there open souce projects already to detect hypervisor or host OS faults? | + | |
| - | * OpenStackNova devs said it should be kept simple, providers need to monitor processes ontheir own. | + | |
| - | * But there appears to be some open source tools(SNMP polling or SNMP agents on host). Need to pull things together. | + | |
| - | * Next call will be on January 12th. | + | |
| - | + | ||
| - | ==== Dec 15, 2014 ==== | + | |
| - | + | ||
| - | Agenda: | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * wiki/doc structure | + | |
| - | * Agreed to have three sections | + | |
| - | * UseCase (High-level description) | + | |
| - | * Requirement (Detail description, GAP Analysis) | + | |
| - | * Implementation(includes monitor tools and alternatives) | + | |
| - | * Faults table | + | |
| - | * will create table that explain stories for each fault | + | |
| - | * columns would be physical fault, how to detect, effected virtual resource and actions to recover | + | |
| - | * in three categories Compute, Network and Storage, will start on Compute first | + | |
| - | * also try to keep separate table/categories for critical and warning | + | |
| - | * TODO(Palani): provide fault table example | + | |
| - | * TODO(Gerald): create first version of fault table after getting table example | + | |
| - | * framework | + | |
| - | * how we handle combination of faults and feature H/W faults that is still open question | + | |
| - | * suggestion to have fault management "framework" that should be configurable to define faults by developers or operators | + | |
| - | * Gap analysis | + | |
| - | * We should have list of items so that we can avoid duplicated work | + | |
| - | * TODO(Ryota): Post first item to show example how we describe that could be template for GAP analysis | + | |
| - | * Monitoring | + | |
| - | * We should check monitoring tools as well: Nagios, Ganglia, Zabbix | + | |
| - | * Check TODOs from the last meeting | + | |
| - | * seems almost all items have done or started (but we could not check 'fault management scenario based on ETSI NFV Architecture' although there is silde on wiki) | + | |

| - | * How we shape requirements | + | |
| - | * Day of the week and time of weekly meeting | + | |
| - | * Tools: etherpad, ML, IRC? | + | |
| - | * Project schedule, visualiztion of deliverables | + | |
| - | + | ||
| - | Minutes: | + | |
| - | + | ||
| - | * How we shape requirements | + | |
| - | * Use case study first | + | |
| - | * Gap Analysis should be included existing monitoring tools like Nagios etc. | + | |
| - | * How we format fault message and VNFD elements for alarms? | + | |
| - | * Fault detection should be designed within a common/standard manner | + | |
| - | * Those could be implement in existing monitoring tools separated from OpenStack | + | |
| - | * What is "common" monitoring tools, there are different tools and configurations | + | |
| - | * Focus on H/W faults | + | |
| - | * Do we really need that kind of notification mechanism? Can we use error from API polling, just get error detected by application or auto-healing by VIM? | + | |
| - | * Real vEPC needs to know fault that cannot be found by application like abnormal temperature. | + | |
| - | * VIM should not run auto-healing for some VNF. | + | |
| - | * There are two cases/sequences defined in ESTI NFV MANO that fault notification are send from VIM to VNFM and to Orchestrator. | + | |
| - | * Alarming mechanism is good to reduce the number of request from user who pooling virtual resource status. | + | |
| - | * We shall categorize requirements and create new table on wiki page. (layer?) | + | |
| - | * -> A general view of the participants is to have the 'HW monitoring module' outside of OpenStack | + | |
| - | * TODOs | + | |
| - | * Open etherpad page for collaborative working (Ryota) | + | |
| - | * Collect use cases for different fault management scenarios (Ryota) | + | |
| - | * Set IRC (Carlos) | + | |
| - | * Provide Gap Analysis (Dinesh, Everyone) | + | |
| - | * Provide fault management scenario based on ETSI NFV Architecture (Ashiq) | + | |
| - | * List fault items to be detected (Ashiq, Everyone) | + | |
| - | * Day of the week and time of weekly meeting | + | |
| - | * Monday, 6:00-7:00 PT (14:00-15:00 UTC) | + | |
| - | * TODO(Ryota): create weekly meeting entry in GoToMeeting | + | |
| - | * Tools: etherpad, ML, IRC? | + | |
| - | * We will use opnfv-tech-discuss ML with "[doctor]" tag in a subject. | + | |
| - | * We will use "opnfv-doctor" IRC channel on chat.freenode.net . | + | |
| - | * TODO(Carlos): update wiki | + | |
| - | * Project schedule, visualiztion of deliverables | + | |
| - | * All team members are asked to check project proposal page and slides that are approved by TSC and show our schedule and deliverables. | + | |

| - | * Project proposal | + | |
| - | * There were two comments at project review in TSC meeting (Nov 26) | + | |
| - | * Large scope: TSC asked to narrow project scope, creating as requirement projects seems reasonable | + | |
| - | * Overlap with HA project, so collaborate in project activity | + | |
| - | * https://wiki.opnfv.org/requirements_projects/high_availability_for_opnfv | + | |
| - | * Ashiq and Qiao had talked before this meeting, and agreed that we would not eliminate duplication at proposal phase | + | |
| - | * Project proposal was fixed by some members | + | |
| - | * https://wiki.opnfv.org/doctor/project_proposal | + | |
| - | * The project categories was changed to requirement only | + | |
| - | * In new revision of project proposal, we removed detailed descriptions which don't suit requirement project | + | |
