*** aojea has joined #openstack-performance15:37
tovin07besides15:37
tovin07there’a a patch from me15:37
tovin07#link Filter for OSprofiler output https://review.openstack.org/#/c/496543/15:37
tovin07msimonin, you should take a look at it15:38
msimoninthanks, I just added myself :)15:38
tovin07496543 is a very first PoC for your case15:38
tovin07that’s all from me for reviewing15:39
DinaBelovatovin07 thanks for the update15:39
DinaBelova#topic Current status15:40
DinaBelovatovin07 let's proceed with current status15:40
DinaBelovatovin07 please start :)15:40
tovin07hmm, not much from last week15:40
tovin07I publish a patch for filtration15:40
tovin07working on monasca log API as an OSprofiler driver (forgot to publish it, will publish soon)15:41
*** aojea has quit IRC15:41
tovin07rajulk, do you have any news from your side?15:41
DinaBelovatovin07 ack15:41
tovin07for your blueprints?15:42
rajulknothing much. still working to merge the changes to osprofiler for sync15:42
rajulkasync call*15:42
DinaBelovarajulk thanks15:42
DinaBelovailyashakhat anything to share?15:43
ilyashakhatposted some patches on code removal :)15:43
ilyashakhatnow osprofiler is independent from oslo.messaging and doesn't require os-auth vars15:43
DinaBelovailyashakhat yeah, sorry :( this week was a bit crazy after returning from sick leave - will review for sure15:44
ilyashakhatthey are merged already15:44
ilyashakhatthanks to tovin07 and Vipin15:44
DinaBelovailyashakhat well, you have more on review :D15:44
ilyashakhatthat's all I have for now :)15:45
DinaBelovamsimonin rcherrueau okay, so today we have you folks :) anu update from your side? Any news on distributed messaging routing you're working on?15:46
msimoninyes15:46
msimoninThere are two directions actually15:46
msimonindistributed messaging and distributed databases15:47
msimoninregarding distributed messaging we started a test plan for this15:47
msimonin#link https://review.openstack.org/#/c/491818/15:48
msimoninit's still WiP15:48
msimoninbut feel free to check it (especially if you have some ideas regarding the resilience test cases)15:48
msimonin:)15:48
DinaBelovamsimonin gotcha15:49
msimoninIn parallel, we need to code some specifix tool to experiment with qpid dispatch15:49
msimoninthe same it's progressing15:49
msimoninrcherrueau:  want to speak about distributing the database?15:50
rcherrueauyep15:50
rcherrueauOn my side, I am working (with an intern) on making OpenStack supports CockroachDB15:50
rcherrueauCockroachDB is a *New*SQL Database15:51
rcherrueaui.e., A database that scales and still offers ACID transactions.15:51
rcherrueauWe have a POC that deploys Keystone over CockroachDB15:52
rcherrueau#link https://github.com/BeyondTheClouds/openstack-cockroachdb-dev15:52
rcherrueauYou can try it. You only need vagrant15:52
rcherrueauthen it deploys cockroacdb and keystone using devstack15:52
rcherrueauI will make an announcement on the ml soon15:53
rcherrueauNext step is doing performance analysis on CockroachDB vs Galera15:53
ilyashakhatas a spoiler - did you face any issues on making Keystone work with it?15:54
rcherrueauilyashakhat: not that much. We have to patch one file in oslo.db15:54
ilyashakhatsounds cool :)15:54
rcherrueauEspecially because that contains code that is backend specific15:54
DinaBelovathanks rcherrueau msimonin15:55
ilyashakhatthere a lots of error-handling specific things15:55
rcherrueauand we also have to add some python decorators into keystone, but only few15:55
msimoninThis will be fun to deploy at scale ;)15:55
DinaBelovatrue :D15:56
*** klindgren has quit IRC15:56
DinaBelovaokay, it looks like we can proceed to the open discussion15:56
DinaBelova#topic Open Discussion15:57
DinaBelovailyashakhat msimonin rcherrueau tovin07 rajulk - anything to share, that was not yet mentioned?15:57
tovin07yep15:58
ilyashakhatI have a question - do we plan to have sort of plan for the next release?15:58
msimoninilyashakhat: +115:58
tovin07i’m thinking of separating error traces (traces that contain a span with error/exception information) from normal trace.15:59
tovin07in OSprofiler15:59
DinaBelovailyashakhat msimonin I suspect we do not have specific items so far - talking about osprofiler or test plans. Let's probably gather them to one place till next meeting?15:59
ilyashakhatDinaBelova, could you make an etherpad to list our ideas16:00
ilyashakhatyep16:00
DinaBelovayep, one sec16:00
tovin07that is a small change in idea, however, need to modify drivers16:00
tovin07ilyashakhat: +1 too16:00
rajulktovin07 can you share the idea behind doing that16:00
DinaBelova#action ilyashakhat msimonin rcherrueau tovin07 rajulk DinaBelova add ideas to https://etherpad.openstack.org/p/performance-team-q-release-ideas16:01
tovin07rajulk: the idea is quite simple, we can use OSprofiler to trouble-shoot errors in our OpenStack services. I just want to separate error traces out of normal trace and store it in other place —> easy for query. i.e normal traces in redis db 0, error trace in redis db 116:02
tovin07DinaBelova: thanks16:02
rajulktovin07 got it. thanks16:03
DinaBelovatovin07 I'm ok with this idea, but only if it's going to be an optional - not all people are ready to have multiple DBs for profiling and not everybody needs it16:03
tovin07yes16:04
tovin07it should be an option only16:04
DinaBelovacool, thanks16:04
DinaBelovaokay, anything else?16:05
tovin07none :d16:05
DinaBelovait looks like we're done for todays16:05
DinaBelovathank you folks for participating16:06
ilyashakhatthanks!16:06
DinaBelovahave a nice day/evening16:06
