How to know when a cluster member was actived?

[fernandobvds]

Good Morning!

I have a cluster HA environment like this;

{

[Expert@ckp02:0]# cphaprob stat

Cluster Mode: VSX High Availability (Active Up) with IGMP Membership

Number Unique Address Assigned Load State

1              192.168.5.30 0% Standby
2 (local)  192.168.5.40 100% Active          }

I need to know when a clusters member switched standby to active, i need this information with day and hour..

Do We have any commando to see this?

Thank you !
