| 11:55:19 | lyarwood | sean-k-mooney: yeah back to pike would be useful, feel free to post them now if you have time or I can look later today | |
| 11:55:54 | sean-k-mooney | just reading a spec so ill post them shortly. | |
| 14:15:14 | openstackgerrit | Martin Midolesov proposed openstack/nova master: [vmware] Cross vCenter live migration https://review.openstack.org/616590 | |
| 14:29:23 | ThomasWhite | Hey all, a quick question I couldn't find a reliable answer to. How often or what would qualify running the "nova-manage db archive_deleted_rows" command? Is this something I should view as a routine operation, or only a as-needed step? | |
| 14:29:49 | ThomasWhite | Our galera cluster is stable and quick, no pressing need for it nor are we short on space, but just looking to implement any best practices | |
| 14:33:40 | sean-k-mooney | ThomasWhite: that is really up to you. if you want to be proactive and keep the current level of perfromace you could proactivly run that command on a fixed cadance | |
| 14:34:39 | sean-k-mooney | ThomasWhite: but if you have monitoring in place to determin you perfromance is within your accpeatable critia then you could decide to only run it when that critia is not met | |
| 14:35:46 | sean-k-mooney | ThomasWhite: if you upgrade every release then running it as part of your upgrade may be suffient if your cloud is relitivly stable with longer lived instnaces | |
| 14:36:27 | sean-k-mooney | ThomasWhite: if you are running a ci environment where you are constantly spawning and deleteing instance then you might want to run it on a cron job every X weeks | |
| 14:37:46 | sean-k-mooney | i personally would only run it on upgrade or when needed as i dont like fixing things that are not broken but perhaps some operators can share there experiance? | |
| 14:38:25 | ThomasWhite | Awesome - thanks sean-k-mooney. Would removal of individual entries from instance_actions do anything bad either - primarily as we need to take a look at a server (booting through rescue) but not leave the regular user of it with knowledge we've taken a look for compliance. | |
| 14:39:11 | ThomasWhite | Putting into single user could impact data reliability so booting into rescue is the preferred mechanism | |
| 14:40:14 | sean-k-mooney | ThomasWhite: that i dont know the anwser too. it if your billing system cannot elimitate teh run time of the insance using o | |
| 14:40:32 | sean-k-mooney | openstack to start the instance in that case my be ill advised | |
| 14:40:57 | ThomasWhite | Oh we'd only be looking to hide the fact it booted into rescue if that makes sense, the instance needs to continue existing and will be put back to normal post-rescue | |
| 14:41:48 | sean-k-mooney | yes i understand but you would need to remove two things first the fact ti was booted in rescue mode and second the fact it was running at all | |
| 14:42:08 | sean-k-mooney | i dont know of a clean way to do that today | |
| 14:44:21 | ThomasWhite | sean-k-mooney thanks, I'll give it a go and let you know | |
| 14:46:48 | sean-k-mooney | i generally stay away from such topics as i dont really agree with them ethiclaly but there may be a case to be made for having a inspect action that worked like rescue and was admin only that did not recored itself in the db. | |
| 14:47:54 | ThomasWhite | I agree, it isn't a public cloud situation, it's all data owned and operated internally though not to worry | |
| 14:48:03 | sean-k-mooney | that said such an operator capablity could expose the operator to liablity or prevent certen workloads form being used on an openstack cloud as the teanat may nolonger beable to fulfil there compliance requirements as a result | |
| 14:49:12 | sean-k-mooney | ThomasWhite: right it the tanant and the operator is the same company it makes sense in some cases hence why it think there could be an argument made for support this more cleanly | |
| 14:49:46 | sean-k-mooney | for public cloud i would be less keen on this but private could perhaps. | |
| 14:50:47 | sean-k-mooney | i would certenly feel much more comfortable supporting a db manage command to do the clean up of the event or an api then recommending db surgery to do the same. | |
| 14:54:51 | ThomasWhite | I think as a project, nova should probably remain neutral on the politics of it, as it's much more a niche concern. My own is only a one-off regulatory issue rather than regular procedure, so happy to experiment and report back as an FYI for others | |
| 15:39:37 | ThomasWhite | Ok, I removed the entries from instance_actions_events first and then the instance_actions entry for it, and worked like a charm. Done the usual stretch of actions ie rebuild, restart, console etc and works a treat. | |

| 16:17:20 | spatel | sean-k-mooney: morning | |
| 16:17:28 | spatel | are you in summit? | |
| 16:17:50 | spatel | if no then i need 2 min from you.. | |
| 16:18:03 | sean-k-mooney | spatel: no im not im afraid | |
| 16:18:12 | spatel | :) | |
| 16:18:32 | sean-k-mooney | how can i help | |
| 16:18:40 | spatel | i am testing influx + grafana for openstack dashboard... | |
| 16:19:16 | spatel | currently i am using telegraf and it looks amazing | |
| 16:19:27 | spatel | now i am confused what i should use collectd or telegraf ? | |
| 16:19:39 | spatel | need you honest opinion | |
| 16:19:43 | sean-k-mooney | ah ok thats a little out of my are of expertiese but i know its a solution many use. | |
| 16:20:15 | sean-k-mooney | well telegraf is much newer, collectd has more support but it is also a legacy solution | |
| 16:20:19 | spatel | This is first time i am going to use so want to make sure i won't hit the wall moving forward | |
| 16:20:29 | sean-k-mooney | it really depends on what you intend to use it for | |
| 16:21:06 | spatel | people saying telegraf has tags feature which will be very handy which collected doesn't support yet | |
| 16:21:47 | spatel | also telegraf doesn't have libvird support | |
| 16:22:10 | spatel | libvirtd* | |
| 16:22:30 | sean-k-mooney | spatel: well the 2 are not mutally exclcive | |
| 16:22:51 | sean-k-mooney | ralonsoh: you have worked on yardstick can you provide advice to spatel | |
| 16:22:52 | spatel | otherwise I think i will give it a try both and see... | |
| 16:23:12 | openstackgerrit | Dirk Mueller proposed openstack/nova master: Handle alternative UEFI boot loader locations on SLES https://review.openstack.org/348394 | |
| 16:23:20 | sean-k-mooney | i would proably default to collectd jsut becase im slightly more familure with it | |
| 16:23:34 | spatel | make sense! | |
| 16:23:55 | spatel | also telegraf use go lang which is new for me too :( | |
| 16:24:08 | spatel | i can handle python easily | |
| 16:24:15 | sean-k-mooney | mnaser: what solution does vexhost user for its monitoring? is it internal or do you use collectd, telegraf, nagios or zabex | |
| 16:24:32 | sean-k-mooney | spatel: collectd is all or mostly c | |
| 16:24:39 | spatel | mnaser: is in Openstack summit :) i was him on youtube.. | |
| 16:25:13 | spatel | but collected can use plugin written in pythn | |
| 16:25:20 | sean-k-mooney | spatel: yes he is. there will be a lot of people at teh summit that can provide input on this topic. | |
| 16:25:45 | sean-k-mooney | spatel: collectd can use plugins written in python java and several other languges | |
| 16:26:04 | spatel | lets me try both and see who is handy.. | |
| 16:26:16 | spatel | worth exploring them | |
| 16:26:25 | sean-k-mooney | spatel: one of the advantages of it being around and used for so long is there are lots of language bindings | |
| 16:26:48 | spatel | hmm | |
| 16:26:52 | spatel | Point | |
| 16:27:16 | spatel | collectd is little fast because its written in C | |
| 16:28:42 | spatel | I have 165 compute node in my cloud :) running 207 VMs | |
| 16:28:42 | sean-k-mooney | spatel: well i hope that helped a little. enjoy the summit and try not to let two many vendors sell you things you dont need. | |
| 16:28:56 | ralonsoh | spatel, in https://github.com/opnfv/yardstick/blob/master/yardstick/dispatcher/influxdb.py you have an example of how to store the information in influxdb | |
| 16:29:00 | sean-k-mooney | hehe nice | |
| 16:29:05 | spatel | sean-k-mooney: i am in office :( not lucky! | |
| 16:29:30 | ralonsoh | spatel, you also need to retrieve this information from collectd. You can use rabbitmq to retrieve collectd information | |
| 16:29:34 | openstackgerrit | Dirk Mueller proposed openstack/nova master: Handle alternative UEFI boot loader locations on SLES https://review.openstack.org/348394 | |
| 16:29:38 | spatel | thanks ralonsoh! reading... | |
| 16:30:33 | spatel | You can use rabbitmq to retrieve collectd information - this is interesting.. | |
| 16:30:41 | sean-k-mooney | ralonsoh: thanks i rely on you and emma when it comes to monitoring to fill it the gaps as its not someting i normally dable in. | |
| 16:31:06 | ralonsoh | spatel, here you have an example of how to handle the collectd info: https://github.com/opnfv/yardstick/blob/master/yardstick/network_services/nfvi/resource.py | |
| 16:31:29 | ralonsoh | sean-k-mooney, well, I'm not contributing any more to Yardstick (for now) | |
| 16:32:02 | sean-k-mooney | ralonsoh: true but you have much more uptoday knowladge of where things stood then i. | |
| 16:33:10 | ralonsoh | spatel: collectd dumps the information in rabbitmq. How to create a mq consumer: https://github.com/opnfv/yardstick/blob/master/yardstick/network_services/nfvi/resource.py#L111 | |
| 16:33:40 | sean-k-mooney | ralonsoh: collectd can also use the netwroking pluging to dump the data directly into infuxdb too | |
