wllabsthis is my health policy02:31
wllabsi am delete cluster's node or shuddown node, but It seems there is no react02:32
Qimingonly compute fencing is supported02:33
Qimingonly one action can be specified02:33
Qimingthe definition of action list has been changed02:33
Qimingeven if the list of actions is supported, your list doesn't make sense02:34
*** Jeffrey4l has quit IRC02:34
Qimingrecreate should be the last resort when you cannot do any other recovery actions02:34
Qimingback to the problem you described02:35
Qimingyou'd better check if you can still do 'nova show <server-uuid>' after your operation02:35
Qimingif that still works, it means your delete was a soft delete02:35
Qimingalso you will need to check senlin logs and/or events02:37
Qimingthose are the tools provided you for debugging02:37
wllabsonly one action can be specified  ?02:38
wllabsdon't list ?02:38
wllabslist have only one action?02:39
wllabsi try it, ==02:39

wllabsi use newton verion of senlin03:02
wllabswhether support health policy  ?03:03
Qimingit was experimental03:03
Qimingand it is still experimental03:03
Qimingwe are explicitly stating that after the support status for profile types and policy types are added03:04
wllabsnewton load balance whether stable ?03:04
QimingLB was tested03:04
Qimingbut I cannot speak for the load balancing service itself03:04
wllabsi want use senlin,  What features can be used?03:06
wllabsWhat policy can be used?03:06
*** guoshan has quit IRC03:07

wllabsLoad-balancing policy is the role of the node in the cluster changes, the lb member will update?05:44
wllabsWhat to do the lb policy ?05:45
wllabsLb policy is used to do what?05:46
Qimingload balancing05:46
wllabsif delete node the lb will change member ?05:47
wllabsIf delete node, lb will change the member ?05:47
wllabsLoad-balancing policy to do this ?05:48
wllabsauto ?05:48
Qimingsenlin does this for you05:51
wllabsthank a lot for you05:51
wllabsif one node shutdown, lb will change the member ?05:54
wllabslb will aoto change the member ?05:54
Qimingnot yet05:58
Qimingyou have to remove the node from the cluster manually05:58
wllabsonly support scale in and scale out ?05:58
Qiminglb policy is triggered by senlin actions05:58
Qimingnot by events in other services05:59
wllabsok, understand05:59
Qimingthough it can be improved05:59

yanyanhuhi, ruijie, are you there?06:37
yanyanhuI'm back :)06:37
wllabsheat seem like can automate lb06:46
wllabsThe first resource you will provision is the health monitor configuration that will check the VMs under the load balancer. If the VM is down, the load balancer will not send traffic to it06:46
Qimingthat is not heat's capability06:47
Qimingit is the load balancers06:47
Qimingif a load balancer is capable of doing health monitoring, senlin LB policy automatically gets that capability06:48
wllabsheat can create monitor07:03
wllabscan senlin create monitor ?07:03
Qimingwhat do you mean by monitor?07:04
*** zhurong has joined #senlin07:05
wllabsOS::Neutron:: LBaaS ::HealthMonitor07:05
wllabs定义健康监视器,根据自定的协议,比如 TCP 来监控资源的状态,并提供给 OS::Neutron::Pool 来调整请求分发07:05
wllabslb是会根据 monitor来调整流量分发07:07
wllabssenlin现在不能创建 monitor吧07:07
*** fabian4 has quit IRC07:12
yanyanhuhi, wllabs, senlin will create healthmonitor when a lb policy is attached to a cluster07:12

ruijiewas writing slides ..07:14
ruijiehi yanyanhu, still there?  :)07:15

ruijieem, let me see07:18
yanyanhuand if you need adjustment on the time slot allocation, we can make a change07:18
yanyanhuruijie, thanks :)07:18
ruijieI think I can finish it in 40 min, since I can put some questions to open discussion07:19
*** yuanying has joined #senlin07:19
