alcabreragood morning, all. o/13:32
sriramaye aye13:32
maliniHere comes the first bencmark results
mpanettaThat was fast13:36
sriramget claims are super fast13:39
*** amitgandhi has quit IRC13:41
*** amitgandhi has joined #openstack-marconi13:41
* alcabrera reads the thing13:42
alcabrerathese are looking pretty speedy13:42
alcabrera'cept maybe post message13:42
maliniI think it gets slowed down with messages in the DB13:42
alcabreramakes sense13:43
maliniWe should try with empty DB/ vs DB with messsages in it13:43
sriramthis was on fresh DB right?13:43
alcabrerasriram: I have no idea. :P13:43
sriramalcabrera: thats ok :)13:43
malinipost_message takes longer towards the end of the test13:44
malinitht means , as DB starts getting populated13:44
*** ayoung has joined #openstack-marconi13:44
openstackgerritOpenStack Proposal Bot proposed a change to openstack/marconi: Updated from global requirements
mpanettaYeah, but you also have more concurrent connections at that time13:45
sriramhmm, interesting.13:45
mpanettaOuch, 5 seconds13:45
malinimpanetta: but why is it just slow for post_messages in tht case?13:45
mpanettaGood question13:45
mpanettaI am trying to find a mongodb thing to run while testing13:45
srirampost_claim should also slow down then.. if its slowing down for posts. but that isnt the case.13:46
malinimpanetta: We used to have a mongo DB monitoring thing, rt?13:46
maliniwhere we wud login to their website?13:46
*** balajiiyer has joined #openstack-marconi13:46
mpanettaOh, no we don't pay for that13:47
malinihmm..I thought it was a free one...13:47
mpanettaOh, not that I know of.  I only know of MMS13:48
maliniyeah,..tht is the one13:48
maliniis it a paid service?13:48
mpanettaI thought it was13:48
malinilet me try to find my old login13:49
mpanettaYou may want to run mongotop on all 3 RS members when doing the test13:49
*** Obulpathi has quit IRC13:49
mpanettaAlso you could port forward the http console back to yourself13:50
*** Obulpathi has joined #openstack-marconi13:50
openstackgerritOpenStack Proposal Bot proposed a change to openstack/python-marconiclient: Updated from global requirements
maliniis mongotop similar to top?13:50
mpanettaIt displays all the reads and writes13:51
mpanettaI think it may show lock times as well13:51
mpanettaThe link above talks about it13:51
malinisriram: can you configure mongotop on our RS?13:52
sriramworking on it13:52
*** cpallares has joined #openstack-marconi13:53
mpanettasriram: Did you see the link I posted above with the different monitoring tools?13:54
maliniI can still see our servers & basic profiling data in the mms site13:54
malinilooks like some of it might be free13:54
maliniI'll add mpanetta & sriram to the group we have13:54
mpanettaHow do I access it?13:55
maliniI'll add you & I think you'll get an email13:55
mpanettayep got an email lol13:56
malinisriram, mpanetta: added you both to the group13:56
maliniWe will need to add our mongo servers to mms13:56
maliniinstall mms client in mongo servers?13:56
*** shakamunyi has joined #openstack-marconi13:59
mpanettasriram: Can you do that?13:59
sriramlet me check on that, mongotop works on the individual boxes. I'm looking at connecting directly to the replica set13:59
srirammpanetta: ok13:59

malinimpanetta: does mongotop give more info than MMS would?14:00
maliniwondering if it might be easier to set up MMS?14:00
mpanettaall you have to do to use mongotop is run it14:00
*** cpallares has joined #openstack-marconi14:00
*** chandan_kumar has joined #openstack-marconi14:01
sriramyeah, that works14:01
sriramneed to connect to entire replica set at once.14:01
malinisriram: "need to connect to entire replica set at once." Can you do that ?14:02
maliniI mean is it possible to do that?14:02
*** kgriffs|afk is now known as kgriffs14:02
sriramI'm looking at it now. it seems possible according to the docs14:02
malinihello kgriffs!!14:04
maliniwe have started doing the benchmarks today14:05
maliniThis is our first report
srirammpanetta: replica set seed name, does it refer to the primary?14:07
mpanettaI think it may be the name of the replica set14:08
mpanettatest-rs1 I believe is the name for the shard, the catalog will be catalog-rs114:08
sriramok cool! :)14:09
flwangkgriffs: alcabrera: malini: ping14:15
alcabreraflwang: o/14:15
malinisriram: can you run the tests again (after cleaning out the dbs), once you have mongo monitoring in place?14:16
flwangmy travel is cancelled :(14:16
maliniflwang: :(14:16
alcabreranoooo. :(14:16
malinisriram: I have a meeting with my boss in 10 minutes14:16
flwangI assume you guys understand the reason14:16
sriramflwang: :(14:17
flwangmalini: sorry for the absence14:17
srirammalini: ok will do14:17
alcabreraflwang: I think so. you'll be missed!14:17
mpanettaAww man, that sucks flwang :(14:17
mpanettaI wanted to get to meet you14:17
flwangsorry guys, it's bad i know14:18
flwangSurvey: anybody is using Mac OS as development environment?14:26
alcabreraxubuntu 13.10 here.14:26
sriramI tried, but shifted to linux.14:27
flwangthanks, guys, I'm wondering if i should shift to Mac, seems the answer is no14:28
alcabreraI think kgriffs is using mac os14:28
amitgandhiflwang: some ppl here use a mac but install linux on it14:29
amitgandhii run it with osx14:29
srirammac runs a different version of python, also having multiple installations of python can be a pain on mac.. macports,pythonbrew lots of customizations..14:29
amitgandhiyeh you need to install homebrew to get the initial configuration set up14:30
amitgandhibut then once you have virtualenv it tends to be ok14:31
flwangnow I'm using Thindpad x230 and installed devstack + eclipse + pydev as my dev env, now I'm thinking if Mac is good os for openstack development14:31
amitgandhibut sometimes updating osx to the next major version messes with the python14:31
flwangamitgandhi: thanks a lot14:31
flwangand ubuntu 12.04 to get devstack worked perfect14:32
sriramamitgandhi: how do you deal with multiple python versions on a mac? 2.7 and 3.314:33
sriramI couldnt get tox to work properly on a mac. :|14:33
amitgandhisriram: havent had to deal with that yet =P14:33
alcabrerasriram, amitgandhi: I hope it's like working with py2/py3 on linux. python3.3 gets symlinked as python3.3 and python3 on the path and python2.7 gets symlinked as python, python2, and python2.714:34
flwanganother question, can Mac work with Mac OS + Ubuntu perfectly?14:34
alcabrerasimilarly, I also have symlinks for python2.6 and python3.4, as well as pypy and pypy314:34
sriramflwang: yeah you can dual boot using rEFIt14:36
flwangsriram: got it, thx14:36
sriramI had some problems with wifi in my earlier macbook, had to modify broadcom driver and build it from source :|14:37
sriramso wifi issues might be there, maybe its fixed with recent macbooks :)14:37
flwangthanks for the tips14:40
sriramhttp:// , the results of mongotop on the replica set while running a tsung test14:41
kgriffssriram: do you use homebrew on your mac?14:47
mpanettaOh man, those results suck :(14:49
sriramkgriffs: yep14:49
*** flwang has left #openstack-marconi14:49
kgriffshmm, so do I. After brew install python and python3, tox should work14:51
sriramyeah, I must revisit it. This was some time ago14:51
sriramI ran into some weird errors and just switched to using linux.14:52
kgriffsoic. If you can share a gist with the errors or something I can help14:52
sriramsure, I'll try it out soon :)14:53
mpanettasriram: You know what is weird about that log, even the reads are taking an insane amount of time.14:53
mpanettaTo local oplog anyway14:54
sriramyeah.. something is going wrong somewhere14:54
mpanettaThis is insanity14:54

alcabreramalini, kgriffs, flwang, flaper87|afk:  -- I added a section detailing differences between Marconi and oslo.messaging15:07
alcabrerareview requested. :)15:07
alcabrerathe formatting is a little wonky15:07
flwangalcabrera: cool, thanks for working on this15:07
alcabreraI really want nested bullets in the wiki. :/15:07
kgriffsalcabrera: cool, I'll check it out15:08
kgriffsalcabrera: **15:08
alcabrerathanks, kgriffs!15:08
* kgriffs hates mediawiki syntax15:08
alcabreramuch better15:08
flwangalcabrera: should we add a simple statement like: oslo.messaging is a python library, Marconi is a messaging service(via REST API)?15:10
alcabreraflwang: I may have expressed that as "oslo.messsaging is a library -- Marconi is an HTTP API". Do you feel this is clear enough?15:11
flwangalcabrera: yep, i missed that line :)15:12
kgriffs<random>Etcd looks like a pretty sweet replacement for much of what you might use zookeeper for.</random>15:12
flwangalcabrera: but TBH, I would like to highlight we're service15:12
kgriffsalcabrera, balajiiyer, mpanetta:
kgriffs"connection and rate limiting"15:14
alcabreraflwang: "Marconi is a service over HTTP API" -- done. :)15:14
flwangalcabrera: awesome15:14
alcabrerakgriffs: more leaky buckets. :)15:16

alcabreraDiscworld day makes me want to Postal. :)15:46
alcabrera*go Postal15:46
mpanettaI'm not familiar with that one15:47
alcabreraDiscworld -- I believe that's a universe crafted by Terry Pratchet, mpanetta15:47
cpallaresalcabrera: I looove the discworld series :D15:47
alcabreraGoing Postal was one of the books in that universe15:47
alcabreraI've read just the one book, cpallares, but there's sooooo much to read. :D15:48
mpanettaI'm familiar with the books, just not what the day is for.15:48
alcabrerawhich is great15:48
mpanettaI only read one... I think it was discworld, so long ago...15:48
cpallaresalcabrera: they're so funny! I really like them15:48
cpallaresalcabrera: you should read more of them :P15:48
mpanettaI know it was pratchett...15:48

alcabrerahahaha, the babelfish15:54

cpallaresmpanetta: which discworld novel did you read?16:01

* mpanetta is running on like 3 hrs sleep16:02
mpanettaOk, someone has apparently written a compatible replacement for MongoDB called TokuMX...16:03
mpanettaHmm, or maybe it *IS* mongodb... but highly optimized..16:04
alcabrerait's some serious marketing. @_@16:05
alcabreraI'm so dubious16:05
mpanettaBleh *Patented*16:05

mpanettaAny time someone says *patented* in a flyer...16:05
mpanettaI go...  Ok NEXT16:05
mpanettaSo what if it is patented...16:06
mpanettaPatented means jack all... heh16:06
alcabreraif anything, patented tells me that I have every reason to mistrust them, because they stand in the way of progress16:06
mpanettaPretty much16:06
