DinaBelovahello folks :)15:30
DinaBelovalet's see who is around15:30
tovin07hello o/15:31
DinaBelovamsimonin tovin07 rama_y o/15:31
rama_yhello15:31
rama_yo/15:31
DinaBelovamsimonin akrzos are you around folks?15:31
msimoninHi all15:32
ilyashakhato/15:32
DinaBelovailyashakhat o/15:32
DinaBelovaokay, so let's get started15:32
DinaBelovafirst of all sorry, for the closing last meeting15:33
DinaBelovaI had an unexpected issue to get solved15:33
DinaBelovalet's start with aciton items15:33
DinaBelova#topic Action Items15:33
DinaBelovatovin07 msimonin did you guys have an opportunity to think about osprofiler filtering ideas?15:34
tovin07currently, no15:34
tovin07:D15:34
tovin07msimonin: do you have any starting idea?15:34
msimoninOk so I can start we one use case15:35
msimoninwith*15:35
DinaBelovashoot15:35
msimoninFirst one is :15:35
msimoninI want to extract every event whose name match *RPC*15:36
msimonin(easy)15:36
msimoninSecond is :15:36
msimoninI want to extract every event whose name match *RPC* but also every parent events until the root15:37
msimoninin other words I want to keep everything that causes an RPC15:37
msimoninThese are the 2 first use cases that comes into my mind15:37
DinaBelovafrom what I remember this might be tricky due to the current calls tree structure within the osprofiler15:38
DinaBelovait needs to be checked separately15:38
ilyashakhatshouldn't this be done on database/consumer side?15:38
tovin07ok msimonin15:38
tovin07ilyashakhat: yes, filtering with a large trace should be done in server side15:38
DinaBelovailyashakhat yes, it should15:39
DinaBelovaso right now we are talking not about the client in fact15:39
ilyashakhatso idea is for osprofiler client?15:39
DinaBelovailyashakhat it may be a case, but right now we have none :)15:40
msimoninIs there any known langage to query such a trace ?15:40
DinaBelovatovin07 may I ask you to take a look on this problem?15:40
msimoninthat could be exposed to the client15:40
tovin07yep DinaBelova15:41
*** msimonin has quit IRC15:41
*** msimonin has joined #openstack-performance15:41
DinaBelova#action tovin07 take a look on the osprofiler filtering use cases #1 and #2 and share implementation ideas15:41
DinaBelovamsimonin I guess this is something to investigate15:42
tovin07got it :D15:42
msimoninfor the 2 examples above I have a code that go through the big json and give the result15:42
DinaBelovaplease link here just in case15:42
msimoninactually rcherrueau wrote it15:42
msimonin#link https://github.com/BeyondTheClouds/osp-utils15:43
DinaBelovamsimonin thanks15:43

msimoninthanks15:51
tovin07core reviewers of ceilometer said that I should not add osprofiler to it, because of deprecated things in ceilometer project15:52

jethro7_ Hi folks, so I am trying to figure out some performance issues that I saw while using rally to do the benchmark jobs. What i did is run the same rally workload 10 times in a packstack provisioned vm. Clearly there are performance variations and I was told it might be related to the stability of a openstack environment. Do you guys have any insights? Thx18:18
jethro7_I have plotted a graph too  https://raw.githubusercontent.com/shwsun/xavier-contrib/master/rally/figs/create_and_delete_volumes.png18:19
