Sounds like a use case for the alerts-feature coming with pacemaker-1.1.15.
You can configure alert-agents to be called in the cases mentioned.
Meanwhile there should be high-level-tooling support from crmsh & pcs.
Legacy features for a similar purpose are ClusterMon-RA & cluster-properties
notification-agent/recipient.
