benoithello15:25
benoiti have a large number of measures to proceed with gnocchi (300k env), how can i delete all pending measures to proceed ?15:26
gordcbenoit: what version of gnocchi you have?15:28
gordcand what backend storage driver?15:29
benoitgordc: 3.0.11 / swift15:29
gordcbenoit: 300K env means you have 300K measures to be processed?15:30
benoitgordc: yep (gnocchi status output)15:30
gordcbenoit: there isn't really a way to clear pending (becasue that's essentially throwing away data)15:30
benoitgordc: gnocchi-metricd process were freezed for a while15:31
gordci would probably suggest you make your processing_delay shorter... and/or hack the code https://github.com/gnocchixyz/gnocchi/blob/stable/3.0/gnocchi/cli.py#L142 to use a higher TASKS_PER_WORKER15:32
*** jmlowe has quit IRC15:32
gordcwhat do you mean freeze?15:32
benoitgordc: is that a issue throwing them away ? (if do not care of this metrics for now ?)15:32
*** jmlowe has joined #openstack-telemetry15:32
gordcbenoit: i guess not.. you'll need to delete some containers in swift15:33
gordcprobably easier to just disable gnocchi-api and let metricd clean it for you.15:33
benoitgordc: i have 3x16 workers, and processing delay to 20, tweaking them, is just to much IO intensive15:34
benoitgordc: are measures to proceed already in swift ? i thought metrics to process was to store them in swift (metricd job) ? did i missunderstood the process ?15:35
gordcbenoit: how many metrics does it say you have? (not measures)?15:35
benoit800 metrics / 261 000 measures15:36
gordcbenoit: in v3, pending measures are stored in same place as processed measures.15:36
benoit(sorry for using metrics instead of measures)15:36
gordcbenoit: there's a 'measure' container in your swift that you'll need to delete15:36
gordcbenoit: i think if you change your TASKS_PER_WORKER to something larger, it might help (the scheduling isn't good in v3.x)15:38
gordcbut yeah, swift driver has a lot of IO... only ceph/redis drivers have solution that minimises IO15:39
benoitgordc: ok for TASKS_PER_WORKER, it's actually set to 16 - how much can I raise it ?15:40
benoitchecking also how to find "measure" container to delete15:40
gordcbenoit: depends how many active metrics you're capturing and how many workers you have. see: scheduling in v3.x is subpar :(15:41
gordcbenoit: if it's 800 metrics, i would raise it 2x (if you keep 3x16 metricd)15:42
benoitgordc: ok, i will check that. i have disable some metrics i do not care (principally only capturing instance ones)15:43
benoitbtw i find the measure container :p - there is also a lot of "gnocchi.XXX" containers15:44
gordckk, yeah, play around with that. (or upgrade to v4 to avoid the hacking)15:44
gordcthe gnocchi.XXX is the containers which store the actual values you get when you GET measures15:45
benoitdo i just need to do "swift -U service:gnocchi delete measure" ?15:45
gordcmeasure container is an intermediate step15:45
benoitok15:45
gordc... i don't actually use swift driver so i don't know swift command15:46
benoitok lets try it :p15:46
gordcis your measure container full of measures with the same metric_id?15:46
benoiti just launch the delete command15:47
gordcin that case, i think increasing TASKS_PER_WORKER will clear up the 300K measrues really fast (since it processes them in bulk)15:47
gordclol nm15:47
gordcgnocchi should recreate that container if you restart.15:48
benoitok, delete is still ongoing15:52
*** p01nt3r75 has quit IRC16:06
*** yassine has quit IRC16:10
benoitgordc: still deleting - i dont know how long it will take - thanks for your help16:14
gordcwow, it takes that long to delete?lol16:16
gordcshould try bulk delete next time :P16:16
benoitlol, yes i m surprise it take so long ...16:17

gordcNostawRm: if you didn't figure it out, you should search on instance_id http://gnocchi.xyz/rest.html#searching-for-resources20:10
NostawRmwow, really not a lot of activity here :P I'm still doing what I was because I don't believe that instance_network_interfaces doesn't have just the direct instance_id anywhere, trying to double check now but i recall looking for it20:12
NostawRmgordc, i mean, I guess it is there, suppose I could do a 'like' to do just the instance id in the original_resource_id but I've already got it to get the entire original_resource_id20:14
gordccanadian holiday... and yeah. there are very few devs... and not in north america.20:14
NostawRmlol I was just surprised that my question wasn't pushed out of my scroll back20:14
NostawRma lot of the other channels would've done it on joins/parts alone20:15
gordcNostawRm: i was looking at logs. :)20:15
gordci vaguely recall it should map to original_resource_id but i'm not 100%. i could just be making that up20:16
NostawRmits a shame there's not more activity, the idea behind it all is great, addressing a problem I didn't even consider. I wish my plans were to use it to its fullest but right now we're only using it to track monthly bandwidth usage :/20:17
NostawRmoriginal_resource_id for an interface ends up a real mess, like instance-000000d2-12831df5-442e-45da-a42c-9aabfffe1490-tapc2631880-1d20:17
NostawRmwhich, iirc, is '<libvirt instance name>-<openstackuuid>-tap<first 11 characters of port uuid>20:18
gordcyeah, that's because of ceilometer... there is no unique id for network iirc20:18
gordcthere's https://bugs.launchpad.net/ceilometer/+bug/138312320:19
openstackLaunchpad bug 1383123 in Ceilometer "vnic's resource_id contains redundant information" [Medium,Triaged]20:19
gordcbut we never figured out how to handle it better without breaking old code... or what we have is our attempt20:19
NostawRmno complaints really, I'm using Rackspaces 'php-opencloud' library and I was trying to see if there was an option other than searching to get the resource by original_resource_id since it there should only ever be one that matches20:21
NostawRmbut that was a minor complaint and "fixing" it in gnochhi would just move where the same logic is done20:22
gordccool cool. if you have a workaround then that's good. i don't really see it being fixed on ceilometer pov. maybe gnocchi if you think it can be done there.20:23
NostawRmnah, no reason to, I get tunnel vision and make mountains out of mole hills20:23
