HP Insight Cluster Management Utility - Manual (Page 98)

Description
A quote-contained string to describe in a few words what the sensor is. This appears in the
GUI.
Time multiple
An integer value that determines when the sensors are monitored. If the monitoring has a default
timer of 5 seconds:
•
A time multiple of 1 means the value is monitored every 5 seconds.
•
A time multiple of 2 means the value is monitored every 10 seconds.
Data type
This can be numerical or a string. A string sensor cannot be displayed in the pies by the
interface.
Measurement method
This can be either Instantaneous or MeanOverTime.
•
Instantaneous returns the sensor value immediately.
•
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
The command to be executed by the script. This can be an executable or a shell command.
The executable and the shell command must be available on compute nodes.
6.5.3 Alerts
Each alert contains the following fields:
Name
The name of the sensor as it appears in the Java GUI. It must consist of letters only.
Description
A quote-contained string to describe in a few words what the sensor is. This appears in the
GUI.
Severity
An integer from 1 to 5. A fatal alert is 5 stands. A minor alert is 1. This appears by the interface.
Time multiple
An integer value that determines when the sensors are monitored. If the monitoring has a default
timer of 5 seconds:
•
A time multiple of 1 means the value is monitored every 5 seconds.
•
A time multiple of 2 means the value is monitored every 10 seconds.
Threshold
The threshold that must not be overcome by the sensor.
