Nagios Support Forum

Look at the nagios logrotate config in /etc/logrotate.d
Look at files in /usr/local/nagios/var and/or /usr/local/nagiosxi/var for logs that aren't rotated or kept too long.
Create another logrotate file and add rules from what you found above.

To show the join a cluster page, remove the installed file and restart the host.
# rm /var/www/html/nagioslogserver/application/cache/installed

./upgrade: line 39: 613624 Illegal instruction (core dumped) wget "$assets$pkgname"

Maybe edit the script and add
echo "\n\n$assets$pkgname\n\n"
On line 38

I make a backup of the nagios 01 system via the backup script, scp the file to the 02 system and restore it.
You can scp or rsync the perfdats if you want that on 02.
You'll want to remove the service and host files on 02 before restoring, restore, then run th reconfigure script.

Log in as nagiosadmin and check users.
If the nagiosadmin password is lost, reset it.

/usr/local/nagiosxi/scripts/reset_nagiosadmin_password.php --password=<newpassword>

Why not scp the .gz file from the working NLS to the other and run the upgrade script?

I guess you're new to computers and the internet...
yum install patch
