As discussed with @wido @pyr and @nuxro added an extra log line. Tested it and it logs fine (tested to local disk) when syncing first: Apr 3 15:31:23 mcctest2 heartbeat: kvmheartbeat.sh system because it was unable to write the heartbeat to the storage By the way, it did also log to the agent.log but this extra log has the benefit of ending up in the system log so you'll probably find it easier there. Existing logs: 2015-04-03 15:27:23,943 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout, retry: 0 2015-04-03 15:28:23,944 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout, retry: 1 2015-04-03 15:29:23,946 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout, retry: 2 2015-04-03 15:30:23,948 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout, retry: 3 2015-04-03 15:31:23,950 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout, retry: 4 2015-04-03 15:31:23,950 WARN [kvm.resource.KVMHAMonitor] (Thread-24:null) write heartbeat failed: timeout; reboot the host This closes #145 Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com>
