HP Insight Control for Linux 6.2 User Guide

# NAGIOS GROUP
# This determines the effective group that Nagios should run as.
# You can either supply a group name or a GID.
nagios_group=new_nagios_group
Save the file.
9. Run the Options→IC-Linux→Configure Management Services task.
NOTE: The Task Results window may report completion although the operation might
not yet be complete. Monitor the console to determine the result.
10. If your system has multiple management hubs, log into each management hub server and
repeat steps 2 through 8.
11. There may be instances in which a previous instance of the default nagios user and default
hpadm group exist. To correct this, verify that files the default nagios user previously
owned are now owned by either root or by the new_nagios_user.
If the default nagios user owns any directories or files, change the ownership of these files
and directories to the new_nagios_user.
You can use the following to change the ownership:
# find / -mount -user nagios –group hpadm -print |
xargs chown $new_nagios_user:$new_nagios_group
12. Restart Nagios on the CMS and on the management hubs:
# /etc/init.d/nagios restart
# pdsh -w `shownode clients nagios_monitor` /etc/init.d/nagios restart
