pradkgordc, jd__, should a user be allowed to muck with api-paste.ini ? reason i ask is we're debating if we should keep it in /etc or move to /usr/share in packaging17:52
gordcpradk: allowed? i think so. i turn off keystoneauth in gnocchi that way.17:54
pradkgordc, as in any reason someone should touch this file post install .. ok so one reason to turn it off :)17:55
gordcwell i don't know how often people would be changing it... swift i imagine has a bunch of middleware that might want to be configured.17:57
pradkgordc, so issue is rpm will not replace existing config files and saves them as .rpmsave , causing service upgrade to not configure correctly. if we change it to replace by default, it will override whatever user has configured. If its not a file that user would usually update we can safely assume and replce17:57
gordcwhat's the issue with not replacing them?17:59
pradkthe paste.ini will be outdated18:01
gordcbut it should still work though.18:02
pradkit would but.. like new proxy config etc are missing in old one i think18:04
pradkfor example  pipeline = http_proxy_to_wsgi gnocchiv118:05
*** RafaelMarques has joined #openstack-telemetry18:08
gordcpradk: but that's optional i imagine? i dont know. i feel like users (are expected to|may) modify api-paste.ini initially... i don't know about after that.18:10
gordcbut i would assume it's not necessarily untouched.18:10

flwanggordc: ping22:34
flwanggordc: i have some questions about the swift driver of gnocchi22:34
flwanggordc: based on my understand, when using swift as the storage backend, the metrics data will be saved in swift as a tiny file, is it?22:34
flwangso in this case, how about the performance comparing with a DB backend? thanks22:35
flwangjd__: ^22:35
jd__flwang: I don't even know how to reply to this question lol22:37
flwangjd__: sorry if it's too silly22:37
jd__no it's just that it's orange and apple :)22:37
jd__but if you want to compare the system of storage with Swift in Gnocchi and MongoDB in Ceilometer it's not really the same thing22:38
flwangjd__: the reason why i asked is because Zaqar is thinking to use swift as  a backend as well22:38
flwangto leverage the built-in replication22:38
jd__Gnocch is O(1) with most operations where Ceilometer was at best O(log(n)) with n = number of samples22:38
flwangbut we're not sure if its performance is OK22:38
jd__flwang: if you can use an object storage it will always be more scalable than a RDBMS22:39
jd__but are you sure you don't need a RDBMS ?22:39
flwangcurrently, we support MongoDB and Redis22:39
flwangbut you know, that means user have to deploy them as the pre-step and make sure the replication works22:39
flwangso we're thinking if swift as a backend is another good option22:40
openstackgerritMerged openstack/ceilometer: Convert file publisher to be equivalent to file dispatcher  https://review.openstack.org/39768522:40
jd__it's hard to answer as I don't really know how Zaqar works22:41
jd__but if you think you can do it, it might be a good option22:41
jd__I may help if you have a good description somewhere of how it works and how you would use it22:41
jd__let me know22:41

gordcflwang: i don't have anything to add :) i haven't been testing with swift22:55
gordci don't know about performance. i imagine most databases, you're interacting a lot with in-memory stuff rather than disk22:59
*** chlong has quit IRC22:59
gordci think a few summits/years ago someone had a swift topic about using it as a backend for chat protocol. i think it was a thesis idea though.23:00
stevelleisn't that basically snapchat?23:01
gordcwhat's a snapshot?23:04
