| openstack | The meeting name has been set to 'vitrage' | 08:00 |
| ifat_afek | Hi :-) | 08:00 |
| eyalb | \o/ | 08:00 |
| e0ne | hi | 08:01 |
| ifat_afek | #topic Status and updates | 08:03 |
| *** openstack changes topic to "Status and updates (Meeting topic: vitrage)" | 08:03 | |
| ifat_afek | No special updates today | 08:03 |
| ifat_afek | I’m working on bugs and also progressing with the Nova versioned notifications. | 08:03 |
| ifat_afek | Besides that, Alon and I tried to help with e0ne’s efforts to use xstatic packages in vitrage-dashboard. | 08:03 |
| idan_hefetz | Hi :) | 08:03 |
| ifat_afek | That’s it for me | 08:03 |
| e0ne | ifat_afek: thanks for the help. I hope to get more time for this stuff this week | 08:04 |
| ifat_afek | e0ne: thanks for your help | 08:04 |
| e0ne | I'm working on the tempest plugin refactoring too | 08:04 |
| eyalb | ifat: any progress about that ? | 08:04 |
| ifat_afek | eyalb: about the xstatic? | 08:04 |
| eyalb | yes | 08:04 |
| e0ne | eyalb: I've got working PoC now | 08:04 |
| ifat_afek | Alon and I made it work, but there are some parts we don’t fully understand. So we asked for e0ne’s help | 08:04 |
| e0ne | eyalb: but it didn't work with compressed static :( | 08:05 |
| ifat_afek | I mean, Alon and I finished wht e0ne started :-) | 08:05 |
| eyalb | eOne: do you know why ? | 08:05 |
| e0ne | ifat_afek: :) | 08:05 |
| e0ne | eyalb: not yet | 08:05 |
| eyalb | eOne: whats the error ? | 08:05 |
| e0ne | TBH, I don't have enough time to dig into this | 08:06 |
| ifat_afek | Now compress works, but only if a flag is False, and with some import lines that we are not sure why they are needed | 08:06 |
| ifat_afek | And I’m speaking on behalf of Alon, I was mainly watching what he did ;-) | 08:06 |
| eyalb | if the flag is False it meanes not compress no ? | 08:06 |
| ifat_afek | Yes, but what matters is the value of the flag when you run compress. Compress works anyway, but if you run it with a flag True then later on nothing works | 08:07 |
| ifat_afek | If you run compress with False and then change it to True, it works well | 08:07 |
| e0ne | eyalb: I don't remember which errors I faced | 08:07 |
| e0ne | I can share a PoC to the openstack-dev@ if needed | 08:07 |
| ifat_afek | e0ne: we didn’t face any error. But we started by testing without compress, fixed some issues, and only then tried to compress | 08:07 |
| e0ne | ifat_afek: hm.. interesting. I'll taka a look o it asap | 08:08 |
| ifat_afek | e0ne: when you have the time, we can wait | 08:08 |
| e0ne | ifat_afek: what did you fix? | 08:08 |
| ifat_afek | You removed some scripts from the index.html. In alarms index.html we added the scripts back, but with {{STATIC_URL}} prefix | 08:09 |
| ifat_afek | It solved the missing dagre | 08:09 |
| ifat_afek | Which was needed for the RCA view | 08:10 |
| e0ne | ifat_afek: ok, thanks. I'll take a lookk on it | 08:10 |
| ifat_afek | Thanks! | 08:10 |
| e0ne | ifat_afek: I want to finish this task sooner to start a new one | 08:10 |
| ifat_afek | Sooner is always good :-) and thanks again for your help with that, because we don’t have enough knowledge in this area | 08:11 |
| ifat_afek | BTW we sent you an email with the exact changes we’ve made | 08:11 |
| e0ne | I was o PTO yesterday, didn't read the mail yet | 08:12 |
| ifat_afek | OK | 08:13 |
| idan_hefetz | Currently trying to improve the run time and memory usage of our APIs. | 08:13 |
| idan_hefetz | Mainly topology which is the most wasteful but also resource list. | 08:13 |
| idan_hefetz | Seems there is at least one unneeded graph.copy() that can be removed while changing the algorithm a bit. | 08:13 |
| idan_hefetz | Also, eyalb suggested to compress the data sent via RPC between the api handler and the api. | 08:14 |
| idan_hefetz | Fixing these two issues and testing on a 100,000 vertices graph, shows runtime is reduced to about a half. | 08:14 |
| ifat_afek | Wow | 08:14 |
| idan_hefetz | Hope to commit these changes soon | 08:14 |
| eyalb | we tryed using gzip for the http transport but there wasn't much improvment | 08:15 |
| eyalb | although we saw that the http content was reduced | 08:15 |
| ifat_afek | So most of the time is spent on the sub-graph queries? | 08:15 |
| eyalb | i guess that it is good only for gigs of info | 08:15 |
| ifat_afek | I mean graph queries | 08:15 |
| idan_hefetz | mabey if the network is slow it will be more noticable | 08:15 |
| eyalb | i saw that glance added this option for there images but it is not used by default | 08:16 |
| idan_hefetz | ifat_afek: no actually most of the time is spent copying the graph to provide a result that is different from the original graph | 08:16 |
| idan_hefetz | and also spent outpuing it to a json | 08:17 |
| ifat_afek | Ok, thanks | 08:17 |
| idan_hefetz | eyalb: this change can be added to the configuration, so we can document it | 08:17 |
| eyalb | we can add it is just a config | 08:18 |
| e0ne | idan_hefetz, eyalb: it would be great to see some profiling results | 08:18 |
| idan_hefetz | sure i'll try to create something documented, please send an example if you have something in mind | 08:20 |
| e0ne | sounds good | 08:22 |
| ifat_afek | Any other issue for today’s meeting? | 08:23 |
| ifat_afek | See you next week! | 08:24 |
| eyalb | bye | 08:24 |
