| Qiming | yanyanhu, there? | 09:22 |
| yanyanhu | yes | 09:22 |
| Qiming | so ... some questions about lbaas | 09:23 |
| yanyanhu | ok | 09:23 |
| Qiming | health monitor perspective | 09:23 |
| Qiming | doese lbaasv2 provide an interface to check member status? | 09:23 |
| yanyanhu | yes, I think so. The member status can be observed by listing lbaas member | 09:24 |
| Qiming | em ... | 09:24 |
| Qiming | if i'm basing node health detection on lbaas | 09:25 |
| yanyanhu | but didn't find specific interface for health checking of a given member | 09:25 |
| Qiming | so what's the role of health_mon in it? | 09:25 |
| yanyanhu | hmm, I think hm is kind of backend monitoring service which periodically check the status of node | 09:27 |
| Qiming | yes? | 09:27 |
| Qiming | does hm provide an interface for checking? | 09:27 |
| yanyanhu | and mark the status of physical resource into failed when necessary | 09:28 |
| yanyanhu | no, I think, if you mean initiative health check | 09:28 |
| yanyanhu | e.g. ask for hm to check the current health status of a member | 09:28 |
| yanyanhu | at least didn't see related interface been exposed by neutron | 09:29 |
| yanyanhu | through api | 09:29 |
| yanyanhu | let me recheck the api ref | 09:29 |
| Qiming | so, no proactive interface for hm | 09:29 |
| Qiming | health check is treated largely as an internal mechanism by LB? | 09:30 |
| yanyanhu | no, I think | 09:30 |
| yanyanhu | yes | 09:30 |
| yanyanhu | it is based on the API provided by neutron-lbaas-v2 | 09:31 |
| Qiming | need some affirmative answer here | 09:31 |
| yanyanhu | will try to check api code of neutron lbaas v2 | 09:31 |
| yanyanhu | but no this kind of API interface is exposed based on it API reference... | 09:31 |
| Qiming | its api is documented somewhere? | 09:32 |
| yanyanhu | yes, here, http://developer.openstack.org/api-ref-networking-v2-ext.html | 09:32 |
| yanyanhu | http://developer.openstack.org/api-ref-networking-v2-ext.html#lbaas-v2.0 | 09:33 |
| yanyanhu | this one | 09:33 |
| Qiming | so ... checking this /v2.0/lbaas/pools/{pool_id}/members would be our best bet? | 09:35 |
| yanyanhu | guess so... | 09:35 |
| yanyanhu | we can set the check duration | 09:35 |
| yanyanhu | but still need to wait | 09:36 |
| yanyanhu | for hm to refresh the health status of members | 09:36 |
| Qiming | this one /v2.0/lbaas/loadbalancers/{loadbalancer_id}/statuses | 09:37 |
| Qiming | is it modeled in openstacksdk? | 09:37 |
| Qiming | looks like it is providing a lot of useful information | 09:38 |
| Qiming | oh, I see, it is per-lb | 09:38 |
| Qiming | not per pool | 09:38 |
| yanyanhu | yes | 09:38 |
| yanyanhu | n:1 map I guess between pool/listener and lb | 09:39 |
| Qiming | but this one: /v2.0/lbaas/pools/{pool_id}/members is not providing the operating_status field | 09:40 |
| Qiming | or provisioning_status | 09:40 |
| yanyanhu | let me check | 09:40 |
| yanyanhu | just a status property | 09:41 |
| yanyanhu | which means whether the member is operational now | 09:41 |
| Qiming | are you sure it IS about operational status? | 09:43 |
| yanyanhu | ah, it's based on API ref as well... | 09:43 |
| yanyanhu | I guess it means whether the member is available on specific protocol & port | 09:44 |
| Qiming | API ref? | 09:46 |
| yanyanhu | yes | 09:46 |
| yanyanhu | http://developer.openstack.org/api-ref-networking-v2-ext.html#showMemberv2 | 09:46 |
| Qiming | what is api ref? | 09:46 |
| yanyanhu | status plain xsd:string | 09:46 |
| yanyanhu | The status of the member. Indicates whether the member is operational. | 09:46 |
| yanyanhu | oh, you mean list | 09:47 |
| yanyanhu | not show member details | 09:47 |
| yanyanhu | oh, also has this property | 09:47 |
| yanyanhu | http://developer.openstack.org/api-ref-networking-v2-ext.html#createMemberv2 | 09:48 |
| yanyanhu | ft | 09:48 |
| Qiming | yes, doesn't want to interate thru the list by ourselves | 09:48 |
| yanyanhu | this is create | 09:48 |
| *** shu-mutou is now known as shu-mutou-AFK | 09:48 | |
| yanyanhu | yes | 09:48 |
| yanyanhu | that's low efficient | 09:48 |
| Qiming | http://developer.openstack.org/api-ref-networking-v2-ext.html#showLoadBalancerStatusTree I like this one | 09:49 |
| Qiming | though not accurately documented | 09:49 |
| yanyanhu | http://developer.openstack.org/api-ref-networking-v2-ext.html#listMembersv2 | 09:49 |
| yanyanhu | yes | 09:49 |
| Qiming | the listMembersv2 sample didn't indicate what the 'status' field is | 09:49 |
| yanyanhu | the document said status will be included in list result, but it is not in rest example | 09:50 |
| yanyanhu | s/rest/resp | 09:50 |
| yanyanhu | I think it is there since I can see the status of each member when I list pool member using cmd :) | 09:50 |
| *** elynn_ has quit IRC | 09:50 | |
| Qiming | lbaas api doc is based on WADL, that is why you see xsd:string kind of data types | 09:51 |
| Qiming | need help from you and xinhui on this | 09:51 |
| Qiming | we need to decide how to get health based on load-balancer | 09:51 |
| yanyanhu | sure | 09:51 |
| Qiming | xinhui is not yet checking in any patch in this space | 09:52 |
| yanyanhu | we can make a discussion on this tonight | 09:52 |
| Qiming | have a discussion, not 'make' | 09:52 |
| yanyanhu | yes :P | 09:52 |
| Qiming | :) | 09:52 |
