HP Insight Cluster Management Utility manual Alerts, Alert reactions

•MeanOverTime returns the difference between the current value and the previous value divided by the time interval.

For example, if the sensors return 1, 100, 50, 100 at 4 continuous time steps of 5 seconds:

•HP Insight CMU Monitoring with the Instantaneous option returns 1, 100, 50, 100.

•HP Insight CMU Monitoring with the MeanOverTime option returns N/A, 19.8, -10, 10.

Max value

Used by the interface to create the pies at the beginning. If a greater value is return by a sensor, the maximum value is automatically updated in the interface.

Unit

The unit of the sensor. The GUI uses this measurement.

Command
