HP Insight Cluster Management Utility v7.2 User Guide

IMPORTANT: For HP Insight CMU diskless configurations, only use the DaemonCommands
options provided in the example above. Do not use any option which causes disk I/O.
4. Start collectl:
# /etc/init.d/collectl start
Starting collectl: [ OK ]
5. Configure collectl to start automatically:
# chkconfig --add collectl
collectl 0:off 1:off 2:on 3:on 4:on 5:on 6:off
6.5.6.2 Modifying the ActionAndAlerts.txt file
The ActionAndAlerts.txt file contains definitions for using collectl monitoring. These lines
are commented out so HP Insight CMU works in native mode by default, without collectl. If
you want to switch to collectl, you must comment native and uncomment collectl in
/opt/cmu/etc/ActionAndAlertsFile.txt. For example:
#-------------CPU--------------------------------------------#
#
#- Native
#cpuload "% cpu load (raw)"1 numerical MeanOverTime 100 % awk '/cpu / {printf"%d\n",$2+$3+$4}' /proc/stat
#- Collectl
cpuload "% cpu load (normalized)" 1 numerical Instantaneous 100 % COLLECTL (cputotals.user) + (cputotals.nice)
+ (cputotals.sys)
The command field must start with the string “COLLECTL” in capital letters. The line continues with
a series of collectl variables included in parenthesis and connected with arithmetical operators.
For this example, the cpuload metric reports the sum of cputotals.user, cputotals.nice, and
cputotals.sys.
For a full list of available collectl variables, run the collectl command interactively, as
follows:
# collectl –c 1 -s+C --export lexpr
The -c 1 option runs one shot only. The command output is the list of collectl variables and
the current value:
