Environment Monitoring
Environment Monitoring allows you to configure the thresholds for monitoring. If a threshold value is
exceeded, an alarm is generated. You can also elect to monitor your system for unobserved devices and
generate alarms for missing devices.
To apply Environment Monitoring to your system, you must first select the Enable configuration
checkbox.
You should always monitor your system at the appliance level. When you do, all the other levels are also
monitored. Then, if you have a level that needs to be monitored using dierent settings, you can
monitor that level by overriding the inherited Environment Monitoring and defining dierent settings for
Environment Monitoring.
The following set of thresholds are monitored to see if any of value is exceeded. If a threshold value is
exceeded, an alarm is generated.
