| DinaBelova | klindgren_ - I'm going crazy with my little VM where I'm trying to reproduce your issue via lots of metadata calls :) for some reason my metadata service is not working as expected :D debugging :D | 13:26 |

| klindgren_ | DinaBelova, cool - I htink you are going to need a relative large number of vm's. As many calls to metadata to the same source, will hit the default cache of 15 seconds. So while it will cause some load - its not going to cause (or should not cause) a ton of load on conductor. | 16:09 |

| DinaBelova | klindgren_ - nope, the issue is that I do not see excepted logs at all... it looks like my nova is behaving not very well - I even cannot ssh to the Vms and check the metadata service inside them - nova guys are helping me right now :( | 17:55 |
| DinaBelova | expected* logs | 17:56 |

| SpamapS | DinaBelova: have you considered doing this with the fake driver? | 18:41 |

| SpamapS | DinaBelova: I'm not sure how to fake out the mac<->port<->instance mapping, but then at least you can have thousands of vms on a laptop. :) | 18:43 |
| *** boris-42 has quit IRC | 18:48 | |
| harlowja | right, thats the question i have, fake driver should be fine, but networking might not be (and if vm <-> metadata calls are needed then might need a real vm/something) | 18:57 |
| DinaBelova | SpamapS - I just wanted to take a look on real metadata load :( | 19:13 |
| DinaBelova | and then emulate it with some scripts for instance | 19:13 |
| DinaBelova | or whatever | 19:14 |
| DinaBelova | but real load is far from me :D | 19:14 |
| harlowja | someday u will get real load | 19:14 |
| harlowja | when u are worthy | 19:14 |
| harlowja | lol | 19:14 |
| harlowja | :) | 19:14 |
| SpamapS | DinaBelova: indeed, that first step is a big one. :-/ | 19:14 |
| DinaBelova | :D | 19:14 |
| SpamapS | I'm reading the bit of the metadata code that interacts with lbaas... | 19:16 |
| SpamapS | lots of port and subnet listing | 19:17 |
| SpamapS | :-/ | 19:17 |
| SpamapS | klindgren_: help me out.. this question started when you had to turn off conductor.use_local right? | 19:22 |
| klindgren_ | no - we have been 100% remote conductor since havana | 19:23 |
| klindgren_ | it started two fold, one during hte performance meeting in tokyo where I brought up that our conductor stuff was eating 3 servers worth of cpu. The re-hashed again when nova merged a change that deprecated local-conductor | 19:25 |
| klindgren_ | and a number of large installs that were doing local-conductor was like... um reports of performance issues using remote-conductor - why are we doing this? | 19:25 |
| harlowja | :) | 19:28 |
| harlowja | some of those large installs may be from me, ha | 19:29 |
| harlowja | *cause we haven't turned on remote-conductor yet | 19:29 |
| harlowja | and with stuff like this i'm not sure we still want to :-/ | 19:29 |
