sripriyaKanagarajM: yes, scaling spec was discussed in today's meeting, you can catch up on meeting logs at http://eavesdrop.openstack.org/meetings/tacker/2016/tacker.2016-05-10-16.00.log.html06:23

tbhsripriya, Hey, I want to work on https://bugs.launchpad.net/tacker/+bug/1554280, do you have any thing in your mind on this?06:24
openstackLaunchpad bug 1554280 in tacker "[multi-site-vim] Enable health monitoring for VIM" [Low,New] - Assigned to bharaththiruveedula (bharath-ves)06:24
tbhsripriya, I think it is too late for you now :)06:24
sripriyatbh: well... blame the Time Zones :-)06:25
sripriyatbh: thanks for taking up the RFE, we can start off with some simple VIM monitoring for reachability06:26
sripriyatbh: the bug description pretty much captures what is intended for the feature06:27
tbhsripriya, I thought having a separate class in each VIM driver which runs as a thread, check for authentication06:27
sripriyatbh: there is no reserved scope for the enhancement, feel free to explore06:28
tbhsripriya, or is it just enough to check for reachability06:28
tbhsripriya, okay, I will try out different things, and push a WIP, then work on the comments06:29
jankisripriya: Is the patch for this bug committed?06:29
jankihttps://bugs.launchpad.net/tacker/+bug/157381506:29
openstackLaunchpad bug 1573815 in tacker "VNF row does not highlight color in Horizon on an empty VNF list page" [Low,New]06:29
sripriyatbh: authentication checks happens during vim registration and i believe we dont need to do it periodic intervals06:29
jankiI can see the row in yellow colour06:29
sripriyatbh: keystone reachability should be good enough as a starting point, we could then probably enhance this for quota management and update VIM's health based on that06:30
tbhsripriya, sounds good, thanks06:30
sripriyajanki: did you observe this on an empty list on Horizon06:30
sripriyatbh: cool. thank you.06:31
sripriyatbh: you may want to consider VNF monitoring status also while you implement this06:32
jankisrirpiya: I observed yellow row when a vnf is in PENDING_CREATE state06:33
tbhsripriya, why do we need VNF monitoring in this case?06:33
sripriyatbh: we dont want to be respawning VNFs unnecessarily the moment VIMs are unreachable06:33
sripriyatbh: VNFs on remote VIMs enabled with monitoring06:33
jankiI didnot get what you mean by empty list on Horizon06:33
tbhsripriya, got it06:34
tbhsripriya, you mean whenever VNF monitoring shows failure status, first we need to consider it's VIM health?06:34
sripriyajanki: emtpy list--> no VNFs in VNF Management page06:34
jankisripriya: Haven't observed that06:35
jankisripriya: vnf row chages to yellow colour when in PENDING_CREATE and back to white in other states06:36
sripriyatbh: it also depends what kinda deployment is that VIM, suppose the controller node running keystone goes down, but the actual VNFs are running on compute nodes and they are still reachable, what should we do in such cases06:38
sripriyajanki: can you try the behavior?06:38
jankisripriya: Yes, will do that06:39
sripriyajanki: delete all your VNFs on Horizon, deploy a new VNF and observe the behavior06:39
jankisripriya: ohh this already I have done06:40
jankisripriya: the first one that I created to reproduce this issue itself changed the colour06:40
jankisripriya: to be sure, I created another one and it too changed the colour06:41
tbhsripriya, ah exactly, I was going through the same scenario, but I thought of not taking actions, but show the health status to the client/horizon06:41
sripriyajanki: hmm i see, can you pl reconfirm, we tried on couple of setups and we observed the same behavior where the very 1st VNF created does not highlight color06:43
jankisripriya: sure, will reconfirm and take a snapshot if required06:43
sripriyatbh: what do you mean by not taking actions?06:43
sripriyajanki: yeah please try with a clean slate page where there are no VNFs running and try the scenario, you could update the bug comment06:44
tbhsripriya, like we do in VNF monitoring for example if the VNFs are not reachable we respawn06:45
tbhsripriya, actions: {failure: respawn}06:46
tbhsripriya, I think we can leverage this by taking failure actions input while registering VIM?06:47
sripriyatbh: what kinda failure actions you want to take if VIM is unreachable?06:49
tbhsripriya, I can't think of anything now, so I just want to store the status in db06:50
sripriyatbh: yeah lets get started with that06:50
tbhsripriya, yup06:52
sripriyatbh: cool, calling it a day! will catch up on logs if there are any more discussions.06:54
tbhsripriya, sure, thanks for your inputs06:54
jankiI am installing tacker using devstack and facing this error06:54
sripriyatbh: sure np06:54

jankisrirpiya: Could not satisfy constraints for 'python-tackerclient': installation from path or url cannot be constrained to a version06:56
jankisripriya: is this a known issue. If not, i can troubleshoot06:57

bobhsridhar_ram_: pong16:18
sridhar_ram_qq on the monitoring action policy .. https://github.com/openstack/tacker/blob/master/tacker/vm/monitor.py#L23816:19
sridhar_ram_bobh: we have two ActionPolicy callbacks.. one ^^16:19
sridhar_ram_bobh: .. and another at https://github.com/openstack/tacker/blob/master/tacker/vm/monitor.py#L20816:20
sridhar_ram_for the same respawn action16:20
bobhsridhar_ram_: that one can be deprecated - it was from the nova driver I believe16:20
sridhar_ram_my understanding is only the former is used .. is this correct ?16:20
bobhsridhar_ram_: yes16:20
sridhar_ram_can the other one safely removed ?16:21
bobhsridhar_ram_: I believe so - I don't think it is used anywhere since the heat driver is always used16:21
sridhar_ram_i trying to parse this decorator .. "@ActionPolicy.register('respawn', 'heat')"16:21
sridhar_ram_... how is 'heat' specified during the actual action invokation ?16:22
sridhar_ram_the template only specifies 'respawn'16:23
bobhI need to go back and dig through this - the infra_driver is included as a key to the table that gets built/referenced by the decorator16:23
bobhsridhar_ram_: it's not intuitively obvious but I think it does work16:23
