jd__thanks therve09:46
thervejd__, Do you have an easy way to create an alarm on stuff that doesn't require a VM to be booted09:55
jd__therve: I'd guess so09:55
jd__therve: use aodhclient and gnocchiclient?09:55
jd__you could do it with pifpaf I guess (though there'd be no Keystone)09:56
thervejd__, But what do I need to send? fake meter data?09:56
jd__therve: yes09:56
*** thorst has quit IRC09:56
jd__aodh alarm create ...09:56
jd__gnocchi measures add ...09:57
*** thorst has joined #openstack-telemetry09:57
therveYeah I just need to figure out what '...' is :)09:58
jd__I can build you a small example I guess09:58
jd__give me a few minutes :)09:58
*** thorst has quit IRC10:01
jd__pip is slow…10:03
jd__therve: https://gist.github.com/jd/6c53a9877cad50352fff31aecbd29410 something like that10:06
jd__I realize I need to add aodh-evaluator in pifpaf10:06
thervejd__, Cool thanks10:06
jd__i'm not sure about the details but that's the big picture10:07
jd__I'll look into it more deeply after my shower10:07
jd__I'm interested :D10:08
therve:)10:09
therveYeah I don't seem to manage to trigger the alarm this way10:10
thervebbl10:18
jd__therve: yeah I'll dig into that10:20
jd__that's a good opportunity to find bugs and improve clients in general10:20
*** itsme_ has quit IRC10:21
thervejd__, It'd be cool if an alarm update --state alarm triggered notifications10:21
therveThat would simplify things :)10:21
jd__there's a "blueprint" for that10:22
jd__to have an entire type of alarm manipulated only by http10:22
*** jwcroppe has joined #openstack-telemetry10:26
jd__therve: it's ok10:27
jd__I found the way10:27
jd__therve: https://gist.github.com/jd/6c53a9877cad50352fff31aecbd29410 updated -> be careful that the timestamps of your measure are around NOW() in UTC!10:28
jd__and that works10:28
jd__| state                     | alarm                                               |10:29

thervejd__, OK that sounds good. I still use ceilometer alarms though :)11:55
thervejd__, is meter and metrics the same thing?11:55
*** cdent has joined #openstack-telemetry12:01
jd__therve: meter is Ceilometer, metric is Gnocchi in general12:06
*** pcaruana has joined #openstack-telemetry12:07
thervejd__, is a meter_name in an alarm a metric name?12:07
jd__therve: for Gnocchi resources alarm?12:10
thervejd__, Yeah12:10
jd__yep12:10
jd__like 'cpu' or whatever12:10
jd__not sure of the field name but might be meter_name12:11
jd__metric_name should be more correct but well12:11

EmilienMgordc, jd__: I suggest you to pin tempest in your stable/* jobs15:36
EmilienMwe do it in Puppet CI and reduced errors15:37
EmilienMtempest has tags, and I think our Puppet stable/mitaka CI is pin on latest tag15:37
*** belmoreira has quit IRC15:41
gordcjohn5223: i can't remember why? i feel like i've been told once but i forgot. i imagine something related to upgrade15:45
gordcEmilienM: i have no idea how to do that.15:46
gordcsomething in opnestack-infra?15:46
EmilienMlet me loo15:46
EmilienMlook15:46
gordcjd__: i added chart to track no ops. it starts peaking near when the number of metrics drops (that's probably when the current workload division logic fails too)15:48
EmilienMgordc: something like https://review.openstack.org/328359 not sure this is the right thing to do though, maybe tempest folks can confirm15:52
gordcoh. so we need to update that every cycle?15:53
john5223sqlalchemy for ceilometer is stable right?15:53
EmilienMgordc: yeahaybe15:53
EmilienMmaybe15:53
EmilienMgordc, jd__: also see https://review.openstack.org/#/c/328359/15:54
gordcjohn5223: for storing ceilometer data? it's an option. it's not that performant if you're compute statistics because it has to do it on the fly.15:54

gordcEmilienM: ... it's not 12pm yet.15:54

gordci'll endorse you for clickbaiting15:56
gordc"false hope"15:57
EmilienMgordc: really not sure about the tempest thing, we should ask them15:57
gordcjohn5223: you should look at gnocchi (gnocchi.xyz) if your use case is to run stats/alarms against data. if you want to just dump ceilometer data somewhere you can try the existing built in drivers.15:58
gordcEmilienM: i'll add ken'ichi i guess?15:58

EmilienMgordc: see http://docs.openstack.org/releasenotes/tempest/v12.0.0.html15:59

stevelletak18:20
gordcstevelle: i'm not really load testing it, just trying out a scenario with the 3 nodes i have.18:20
gordcbut might help you decide where to start from.18:21
stevellegordc: just out of curiosity do you use supervisord with uwsgi?18:23
gordcstevelle: nope. not sure what that is to be honest.18:24
gordcfeel free to send me ideas on what i should be monitoring.18:24
gordci'm just taking random metrics from the logs (and profile code i added)18:25
stevellewhat's the init proces for uwsgi for you, systemd?18:25
gordcnot using systemd. one sec. let me grab the command and init file.18:26
gordcstevelle: i'm pretty sure i pip installed uwsgi: http://paste.openstack.org/show/510660/18:31
gordcthat's all i'm doing to start it18:31
*** vint_bra has joined #openstack-telemetry18:31
stevelleand you > uwsgi start gnocchi manually then?18:31
gordcyep18:31
stevellenice on the .ini that's helpful for comparing against my testing env18:31
gordcit doesn't start like other stuff. i basically installed everything with packstack and manually installed gnocchi from source18:31
gordcstevelle: cool cool. there are a ton of options in uwsgi, i just took whatever sileht had set in gate.18:32
stevellegordc:  Per metric injection max looks high, would be helpful to try to identify that outlier18:33
gordcstevelle: yeah, i'm not exactly sure yet. it's more than likely that i just don't know how to set up ceph (i basically used the helloworld guide)18:35
stevelleI would guess the ceph outliers are still from write locks18:35
stevelle(slide 16)18:36
stevelleerr that would be 1518:36
gordcyeah, that's sorta what i'm thinking. i've added more profile code to see whether it's gnocchi or ceph issue18:36
gordci should mention i don't have a dedicate journal disk so not sure if that's the reason for oscillations you see in my charts.18:37
stevelleyou were generating load on the test hosts?18:37
gordceverything up to slide 28 was done independently. so i tested API posting alone (with no metricd)18:37
gordcand then i posted stuff to backlog and tested metricd alone (with no more api posts)18:38
gordcthe ceph nodes should be relatively unused. they're compute nodes but i only have 1 vm on it.18:38
stevellethe asymetry stands out strong in 2218:38
stevellealso 2318:39
gordcyeah, i'm trying to figure that out. the last test i did spread out tasks relatively the same.18:39
gordcthe low host (host1) is actually my controller node.18:40
stevellehost1 was ceph mon, 2 and 3 were store iirc18:40
gordcright.18:41
stevellethis is all great, we are designing for a different environment model which will be interesting to compare with, if we ever get data18:41
gordchost 1 is also my openstack controller node which has everything except the compute service i guess.18:41
gordcstevelle: that sounds great!18:42
