Tuning the reporting rate

The internal VM Monitor daemon sends “heartbeat” messages to vSphere to indicate that the VM is alive. Use the following property, to modify the rate at which these heartbeats are sent.

<property>  
<name>service.monitor.report.interval</name>
<value>7000</value>
<description>  
Interval in milliseconds for sending heartbeats to vSphere.
</description> 
</property>

It is essential that the live VM sends a heartbeats to vSphere at least every thirty seconds.

A smaller reporting interval reduces the risk of missed heartbeats in case an Operating System or Java related process hangs. However, a smaller reporting interval can also have adverse effects - especially if the VM is overloaded.

It is therefore strongly recommended to address the root cause of the VM overload. If your VM is overloaded and becomes unresponsive, we recommend that you either add more CPUs and RAM or rebalance VMs across the cluster.
