gordc | jd__: i'm testing the ceph driver right now. depending on how much padding there (eg. split creates 1 point and 3599 padding spaces), the new format is quite a bit larger in terms of disk space. | 14:31 |
*** liuhanxi has joined #openstack-telemetry | 14:32 | |
dhague | Fun & games with ceilometermiddleware today - when Ceilometer's rabbitmq goes down, the new queue/thread means that Swift no longer blocks. However, when I restart rabbitmq the messagingv2 driver doesn't spot that and the queue just fills up & overflows. Looks like a debug session is on the cards... | 14:34 |
gordc | dhague: sileht is probably the person to ask but he's away for next little while. | 14:37 |
jd__ | gordc: should we be scared? | 14:37 |
gordc | you mean the notifications.info queue fills up? or internal threading queue? | 14:37 |
*** diogogmt has joined #openstack-telemetry | 14:37 | |
gordc | jd__: depends. i have 10TB (30TB with replicas) to get enough IOPs. | 14:38 |
*** links has quit IRC | 14:39 | |
dhague | gordc: the call to notifier.info() never returns from when rabbitmq went down, so the buffer queue that I added just fills up | 14:39 |
gordc | new format is ~400% larger based on the split i have. but it's 2GB vs 9GB | 14:39 |
gordc | so i'm not even near the ceph cluster size... but it is quite a bit bigger. | 14:39 |
dhague | gordc: I'm on it, just venting here in case anyone knows better than I do what's going wrong :) | 14:39 |
dhague | gordc: BTW, would you mind once again giving a +2 to https://review.openstack.org/#/c/295339/ ? No major change since the previous patchset, just minor changes to keep the pep8 and releasenotes checks happy. | 14:40 |

*** yprokule_ has quit IRC | 14:49 | |
jd__ | gordc: compression process… hm | 14:49 |
jd__ | gordc: we could compress once a split is before the back_window | 14:50 |
jd__ | that'd be awesome | 14:50 |
jd__ | gordc: implement me that plz | 14:50 |
nicodemus_ | one question, using current master every metric created has its unit as null. If I wanted to have the unit on each metric, how could I accomplish that? Is it something I need to add to gnocchi_resources.yaml on ceilometer-collector? | 14:50 |
jd__ | gordc: http://2.bp.blogspot.com/-ZZZz5dYg92M/UzkD9ysCalI/AAAAAAAAFJk/8y9bfSDqhHY/s1600/cats-wallpapers-shrek-cats-eyes-desktop-background-pics.jpg | 14:50 |
gordc | jd__: sure. backlog'd (until i figure out how easy it is) | 14:51 |
jd__ | nicodemus_: I think we implemented that in Ceilometer but it might be in Newton only, I don't recall | 14:51 |
gordc | jd__: the only issue i think is for smaller series, the split will probably never be before the back_window | 14:52 |
jd__ | right, it's a problem if you have a lot of very small series | 14:52 |
jd__ | is it supposed to happen? especially with the small split size we set | 14:52 |
gordc | jd__: i think so. most (if not all our default) policies will never be split still | 14:53 |
gordc | jd__: when i asked what policies people were using, they usually had 3 different aggregate policies, and only one of them was greater than our split size | 14:54 |
jd__ | gordc: if you have a chance, you should build out some big numbers I can use for a future blog post on Gnocchi v3 (like 1921939 billions of metric/s or I don't know) | 14:55 |

openstack | Launchpad bug 1367444 in Ceilometer "Need a pollster for cinder volumes and snapshots" [Undecided,Won't fix] - Assigned to Lena Novokshonova (enovokshonova) | 15:01 |
zhangguoqing | https://ask.openstack.org/en/question/92860/ceilometer-volumesize-and-ipfloating-working-issue/ | 15:01 |
nicodemus_ | jd__, I'm looking at kilo code and on compute/pollsters there are several references to the unit, plus the pipeline.yaml has unit on the transformers. Perhaps I need to enable something on the collector to include the unit in the metric creation?? | 15:03 |
zhangguoqing | The above question remain reside, because the volume.size only obtain when create by notification. | 15:03 |
gordc | nicodemus_: it wasn't added to ceiloemter+gnocchi integratino until recently: https://github.com/openstack/ceilometer/commit/104dfe1fc26c6a1aeec7e39b79253e22d70f7901 | 15:04 |
jd__ | nicodemus_: kilo? brml… well look at the git history of the gnocchi dispatcher you'll find what we changed to have unit pushed :) | 15:05 |
gordc | zhangguoqing: why can't you just increase the frequency which cinder sends notification? | 15:05 |
nicodemus_ | gordc, I see. Guess I'll have to upgrade ceilometer( or try to backport that the liberty dispatcher) | 15:06 |

*** rbak has joined #openstack-telemetry | 18:25 | |
gordc | marcin12345: which ceilometer gnocchi dispatcher are you using? | 18:27 |
gordc | in mitaka there is a cache which minimises some calls. in master, there is batching support which minimises calls even more. the batching will probably have best results since gnocchi performs better with batching. | 18:28 |
gordc | you need to also make sure you have enough gnocchi api workers to be able to process your data effectively. | 18:29 |
marcin12345 | gordc: file dispatcher | 18:30 |
gordc | by default, each ceilometer collector has 64 threads, so if you don't have enough gnocchi api workers, it may start backing up | 18:30 |
marcin12345 | mitaka | 18:30 |
gordc | marcin12345: i don't understand. why do you mean file dispatcher but gnocchi? | 18:30 |
gordc | you mean, you are using file backend for gnocchi? | 18:31 |
marcin12345 | I mean backend | 18:31 |
marcin12345 | yes | 18:31 |
marcin12345 | sorry | 18:31 |
gordc | i would check how many API workers you have first. | 18:31 |
gordc | and also if you have anything actually listing to metering.sample queue as nicodemus_ suggested | 18:32 |
nicodemus_ | in kilo for example, when there were a lot of queued messages sometimes you would see collector workers connected as consumers to the queue, but they were non-responsive | 18:33 |
nicodemus_ | a lot = 50.000 queued messages (give or take) | 18:34 |
gordc | yeah, rabbitmq sucks the larger your queue grows. i don't know when it fails, but optimal queue length is 0. | 18:36 |

marcin12345 | Gnocchi api is behind Apache, has 1 process, 32 threads, and yes metering.sample queue is getting messages from publisher, and 32 collectors are consuming it | 18:50 |

nicodemus_ | marcin12345, I found that a 5-process, 32-thread gnocchi API behind apache was still not enough, had to deploy a second gnocchi api | 18:53 |
nicodemus_ | maybe trying with more processes? | 18:53 |
gordc | just for reference, i use uwsgi and i don't even use threads. i have 32 processes, 1 thread. | 18:54 |
gordc | also if you have 32 collectors that means you have potentially have 2048 collector threads sending to 32 api threads. | 18:55 |

marcin12345 | gordc: I will scale up my Gnocchi api then, but if that was a problem I would think I would be getting errors or timeouts, not just unacked messages | 20:41 |
