# You can either supply a username or a UID.
nagios_user=new_nagios_user
# NAGIOS GROUP
# This determines the effective group that Nagios should run as.
# You can either supply a group name or a GID.

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 all files previously owned by the default
nagios user are now owned by either root or by the new_nagios_user.
If any directories or files are owned by the default nagios user, 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 all the management hubs:
# /etc/init.d/nagios restart
# pdsh -w `shownode clients nagios_monitor` /etc/init.d/nagios restart
