| AK_ | Hi Guys | 04:26 |
|---|---|---|
| AK_ | I want to know what is the latest stable mistral version | 04:26 |
| AK_ | could someone please guide me | 04:26 |
| kong | AK_: 2.0.0.0rc2 is the latest mistral release | 04:27 |
| kong | and it will be the final release of mitaka | 04:27 |
| AK_ | where can i find the deb package for it | 04:27 |
| AK_ | @kong https://github.com/openstack/mistral/tree/stable/mitaka are u taking about this ? | 04:28 |
| kong | deb package is not in the scope of many projects | 04:28 |
| AK_ | ohk | 04:28 |
| AK_ | So I have to install from source code is it ? | 04:28 |
| kong | AK_: you can install mistral from source code, and you can also build your own deb package | 04:29 |
| kong | AK_: and puppet module for mistral may be also available | 04:29 |
| AK_ | sure will first do from source code ... | 04:30 |
| AK_ | and then will try debian package | 04:30 |
| kong | AK_: if you just want to try mistral, install from source code is a good choice | 04:30 |
| kong | forther more, actually, we provide docker image for mistral | 04:30 |
| kong | if you are familiar with docker | 04:31 |
| AK_ | nope i am not .. but one of my team mate might be will check with him | 04:31 |
| kong | AK_: FYI, ,http://docs.openstack.org/developer/mistral/guides/installation_guide.html#mistral-and-docker | 04:32 |
| AK_ | thx | 04:35 |
| kong | np | 04:35 |
| AK_ | btw i was before using mistral-server --server api,engine --config-file <path-to-mistral.conf> to run mistral | 04:35 |
| AK_ | but performance is very bad | 04:35 |
| AK_ | can i run this in many worker threads ? | 04:35 |
| kong | AK_: yes, api service is recommended to be run after haproxy or something like that when deployed in production | 04:36 |
| kong | anyway, you can run mistral-server command more than once if you want to do it in multi-worker mode | 04:37 |
| AK_ | so only api server if we run in different that should be fine right ? | 04:37 |
| kong | AK_: I'm not sure I understand you totally by 'only api server if we run in different' | 04:38 |
| AK_ | because i really doubt i good is zero mq between engine and executor | 04:39 |
| AK_ | there are three internal services API , Engine and Executor | 04:39 |
| AK_ | if i run api server separately and run (Engine and Executor together) should it be fine ? | 04:40 |
| kong | AK_: it will be totally fine :-) | 04:40 |
| AK_ | ohk . So performance wise if i run Engine and executor also separately (with Zero MQ) will it be faster ? | 04:41 |
| kong | AK_: first, you need to figure out what exactly the performance problem is, do you have any data to describe that? | 04:42 |
| AK_ | yeah mistral is becoming very slow if i run like 1000 workflows | 04:43 |
| kong | AK_: which command or API is slow? | 04:44 |
| AK_ | that is when i run select count(*) from executions_v2; | 04:44 |
| AK_ | the result if the query goes more that 10k or 20k mistral is becoming slow. | 04:44 |
| AK_ | 5 workflows at a time even then it goes crazly slow | 04:45 |
| AK_ | Presently i am running mistral-server --server api,engine this with one thread ... | 04:45 |
| AK_ | thats why i want to explore more with some other options | 04:46 |
| *** achanda has joined #openstack-mistral | 04:46 | |
| kong | AK_: if what you do is something like performance testing, then you need to put mistral service behind haproxy, and deploy api/engine/executor in different process or even different hosts | 04:47 |
| kong | AK_: then, i think it makes sense for the performance testing | 04:47 |

| AK_ | kong | 04:52 |
| AK_ | sorry i missed out ur replies if u have given any | 04:52 |
| AK_ | i laptop got restarted :( | 04:52 |
| kong | AK_: don't worry, I'll copy msg for you | 04:53 |
| kong | 16:47 <kong> AK_: if what you do is something like performance testing, then you need to put mistral service behind haproxy, and deploy api/engine/executor in different process or even different hosts | 04:53 |
| kong | 16:47 <kong> AK_: then, i think it makes sense for the performance testing | 04:53 |
| kong | AK_: sorry, man, I have to head off for dinner, you can leave your message here, and I believe someone else will help you out there | 04:54 |
| AK_ | ohk | 04:55 |
| AK_ | thx a lot | 04:55 |

| rakhmerov | will know it soon | 06:23 |
| rakhmerov | AK_: can you please file a ticket for this performance issue? | 06:24 |
| rakhmerov | it'd be very helpful for us | 06:24 |
| rakhmerov | and try to put as many details as possible | 06:24 |
| rakhmerov | how your workflows look like, what is your installation etc etc | 06:25 |
| rakhmerov | and what behavior you see | 06:25 |
| AK_ | this is not a performance issues | 06:26 |
| AK_ | I am trying to figure out what are the issues | 06:27 |
| AK_ | presently all the service api engine executor run on one thread which i bad ( which i figured out ) | 06:28 |
| AK_ | now trying to figure out what is the best way to deploy mistral | 06:28 |
| AK_ | BTW where is mistral conference happening this time ? | 06:28 |
