Modifying Cluster Event Logging

It is possible to modify the severity level of the events that are logged by the clupowerd, cluquorumd, cluhbd, and clusvcmgrd daemons. This is done so that the daemons on the cluster systems will log messages at the same level.

To change a cluster daemon's logging level on all the cluster systems, invoke the cluadmin utility, and specify the cluster loglevel command, the name of the daemon, and the severity level. Specify the severity level by using the name or the number that corresponds to the severity level. The values 0 to 7 refer to the following severity levels:

0 — emerg 
1 — alert 
2 — crit 
3 — err 
4 — warning 
5 — notice 
6 — info 
7 — debug

Note that the cluster logs messages with the designated severity level and also messages of a higher severity. For example, if the severity level for quorum daemon messages is 2 (crit), then the cluster logs messages for crit, alert, and emerg severity levels. Note that setting the logging level to a low severity level, such as 7 (debug), will result in large log files over time.

The following example enables the cluquorumd daemon to log messages of all severity levels:

  cluadmin
cluadmin> cluster loglevel cluquorumd 7
cluadmin>
