As I understand it, there are two ways to monitor the status of a resource.
1) Use the monitor action on the resource agent script - this is equivalent to polling the resource at every <monitor interval> 2) Write a value into the cib, and create a constraint rule and scoring to handle failover based on the value of that attribute. This is what the ocf:heartbeat:ethmonitor resource agent does. In the second case, what is the interval at which the cib value is monitored? Does the constraint rule just get checked on an event basis - ie, whenever the cib value changes, the rule is evaluated again)? Thanks, Sam
