HP Insight Cluster Management Utility Stopping HP Insight CMU monitoring, Action and alert files

5.3.8.2Limitations

To display an archived user group, the following conditions must be satisfied:

•Time must not exceed 24 hours.

•The number of nodes must not exceed 4096.

•The number of metrics must not exceed 100.

•The product of the three parameters above must not exceed 409600.

Table 2 (page 77) displays examples of valid combinations of these three parameters.

Table 2 Valid archived user group parameters

Nodes	Metrics	Hours	Nodes*Metrics*Hours
4096	10	10	409600
4096	5	20	409600
4096	100	1	409600
256	100	12	307200
2048	8	24	393216
1024	16	24	393216

IMPORTANT: If the above criteria is not met, display fails with a warning message.

5.5 Tuning HP Insight CMU monitoring

5.5.1 Action and alert files

Sensors, alerts, and alert reactions are described in the /opt/cmu/etc/

ActionAndAlertsFile.txt file.

Following is an example of the contents of the file:
