EPAgent failed to start when using custom VMSTAT script and the EPAgent log shows the following exception:

EPAgent failed to start because: Stateless plugin 'VMSTAT' must have a schedule or delay configured.

introscope.epagent.stateless.VMSTAT.delayInSeconds=900
3.- Save the file and restart the EPAgent for the changes to take effect.
