HP Insight Control for Linux 6.0 Release Notes

Corrective action: Follow this procedure on your CMS to move the RRD directory aside and
rerun the Configure Management Services task, which re-creates the /hptc_cluster/rrd
directory and reconfigures the Insight Control for Linux management services:
1. Move the /hptc_cluster/rrd directory to another file name:
# mv -Rf /hptc_cluster/rrd /hptc_cluster/rrd-save
You may choose to delete this directory instead.
2. Rerun the Configure Management Services task:

2.6.10 Might see CRITICAL or WARNING Nagios alerts for the NodeInfo service
The Nagios default threshold values for total processes, user processes, and zombie
processes might be too small for certain HP ProLiant servers. If so, you will encounter
CRITICAL or WARNING alerts for the NodeInfo service.
Corrective action: Use the following procedure to update the default thresholds in the /opt/
hptc/nagios/etc/nagios_vars.ini file. HP recommends saving a copy of the original file
before making any updates.
1. Save a copy of the original file:
# cp /opt/hptc/nagios/etc/nagios_vars.ini /opt/hptc/nagios/etc/nagios_vars.ini.orig
2. Edit the nagios_vars.ini file to update the values for the *_procs_warning and
*_procs_critical parameters to values that apply to your environment. For example:
[default]
total_procs_warning = 400
total_procs_critical = 500
user_procs_warning = 200
user_procs_critical = 300
zombie_procs_warning = 1
zombie_procs_critical = 5
[service_nodes]
total_procs_warning = 500
total_procs_critical = 600
user_procs_warning = 300
user_procs_critical = 400
zombie_procs_warning = 1
zombie_procs_critical = 5
3. Rebuild the /opt/hptc/etc/sysconfig/vars.ini file and push out the new vars.ini
file to all the managed systems:
# /opt/hptc/nagios/libexec/check_nagios_vars --rebuild
# /opt/hptc/nagios/libexec/check_nagios_vars --update
Vars Warning - icelx[2-6] vars.ini have been resynchronized
NOTE: The vars.ini file is dynamically created from the nagios_vars.ini file, so any
changes to the default Nagios thresholds must be made to nagios_vars.ini, not to vars.ini.
2.6.11 mcelog and mdadm monitoring commands are missing from /etc/sudoers
on the CMS
The monitoring scripts run as the nagios user, and several commands (such as mdadm and
mcleog) that are called by these scripts must be executed with the sudo command. However,
