*** sergio_ is now known as Guest9063914:24
catintheroofjd_: i will deploy gnocchi to collect metrics14:24
catintheroofjd_: but i need to make a decision and i was hopingyou can help me14:24
catintheroofjd_: i need to choose between deploying CEPH as gnocchi backend OR i have a big filer to use as NFS shared between gnocchis and use FILE as gnocchi backend14:26
catintheroofjd_: can you help me make a decision ?14:26
jd_if you deploy Gnocchi to collect metrics, that will not work… but if you deploy it to _store_ metrics, it might ;)14:26
jd_catintheroof: go with Ceph, definitely14:26
catintheroofjd_: jajajjajajaj14:27
catintheroofjd_: can i know your reasons ? please ?14:27
jd_sure14:27
jd_first it's more scalable, as you can easily node to spread the I/O where your NAS will be a SPOF with a lot of contention potentially14:28
jd_second, gnocchi write will be faster since it can append data as it receive them rather than rewrite them14:28
jd_third, you'll be able to shrink/grow more easily14:28
jd_and that's all I'd say14:28
catintheroofjd_: and if instead of gnocchi being on-premises with NFS, gnocchi stands on AWS with EFS shared among gnocchis, "file" backend considerations against CEPH are the same ?14:30
jd_catintheroof: yes14:32
jd_catintheroof: if you go with AWS it's likely better to try S314:32
jd_might be better than EBS14:32
catintheroofjd_: or maybe my question would be ... is CEPH the best gnocchi backend ?14:32
jd_catintheroof: yes and it's written right there http://gnocchi.xyz/master/architecture.html#available-storage-back-ends ;)14:35

silehtgordc, why we have volume.backup.size in gnocchi_resources.yaml ?15:45
silehtgordc, in meters.yaml we have just backup.size15:46
silehtgordc, or what the difference between the backup.size (notification) and volume.backup.size (polling) ?15:47
gordcsileht: ... uh... i don't know. :)15:49
silehtgordc, you added them :)15:49
gordci'll take a quick look15:49
gordcoh.lol15:49
silehtwe have the same kind of thing for snapshot.size and volume.snapshot.size15:50
gordcsileht: yeah, i think i just copied that format15:51
gordcthe snapshot.* meters seem to be historical.15:53
gordcthe polling one with 'volume.*' is new. tbh, i think volume.* is better but we'd need to develop process to rename notification ones.15:53
silehtoki15:54
gordcor we can build both names and disable one in pipeline?15:56
*** nicodemus_ has joined #openstack-telemetry16:01
silehtI don't know the best way, but we need a path to deprecated/rename metrics16:02
*** thorst has quit IRC16:04
gordcsileht: we should probably change the polling names though. since the original notification names are without volume prefix16:05
silehtgordc, we release them already :(16:07
*** thorst has joined #openstack-telemetry16:07
silehtgordc, I have to go, let's think about that with a fresh mind after the weekend :)16:07

*** thorst has quit IRC16:12
gordcyou can try to backport that if you want.16:12
gordccatintheroof: i don't know if it's normal. as long as you have a consumer on all the pipeline queues, you are good.16:12
*** Jack_Iv has joined #openstack-telemetry16:13
catintheroofgordc: well, notification agents consume all messages and put the processed messages on metering.sample16:13
catintheroofgordc: so i think its working16:13
gordccatintheroof: you should be checking ceilometer-pipe* queues16:15

catintheroofgordc: if i dont want to use partitioned notifications but i do want to use them coordinated, is that supported ?16:46
catintheroofgordc: or if i dont use partitioning, goordination is no use ?16:46
gordcthey are the same thing essentially. it won't work if they don't know about each other in some regard.16:48
catintheroofgordc: ok, one more ... could it be that in this partitioned and coordinated mode, i see a greater amount of messages on metering.sample that not using partitioned mode ?16:54
catintheroofgordc: are messages posted differently in this mode to be processed by the collector ?16:55
gordccatintheroof: nope. if it's working properly, it should be exactly same amount of messages to metering.sample16:56

gordcso you see no ceilometer in screen?18:34
Pneumatic_Nope... and I can't find stack.sh.log in /opt/stack/logs,18:35
Pneumatic_I'm developing under stable/ocata, and at least one place I see ominous warnings that the ceilometer API is deprecated, but I think ceilometer is still around , right?18:38
gordcPneumatic_: weird. you should have a log from running stack.sh18:41
Pneumatic_I'm saving one of my own right now.18:42
gordcPneumatic_: ceiloemter api is deprecated yes. but there are other services such as polling agent and notificiation agent which send the data to gnocchi rather than ceilometer-api18:42
Pneumatic_Yep... I'm trying to write a dispatcher/notification module to send data to our in-house time-series DB.18:43
gordcPneumatic_: you'll need to create a publisher since collector is deprecated and we push from notification agent straight to whereever18:45
gordchttps://github.com/openstack/ceilometer/tree/master/ceilometer/publisher18:46
gordci'm not really sure how to help you get ceilometer started... that paste i sent should've insatlled/launched ceilometer18:46
