The user will turn the monitoring OFF for your module using the config
settings in domain.xml. Set to HIGH or LOW to turn it on. To see the
current list of modules to monitor:
asadmin get configs.config.server-config.monitoring-service.*
The monitoring framework will take care of turning on/off the probe so
data collection will be stopped.
