System Profile XI on EL7 fails on nagios.log

[[email protected]]

The System Profile part responsible for collecting nagios.log on EL7 fails. These are the contents of the file:

tail: cannot open '/usr/local/nagios/var/nagios.log\r' for reading: No such file or directory

Tested with XI 5.5.5
EL6 looks fine
EL7 fails

Check the /usr/local/nagios/etc/nagios.cfg file for thelog_file= option. There may be an extra character at the end. The code that pulls the nagios.log looks like:

Code: Select all

nagios_log_file=$(cat /usr/local/nagios/etc/nagios.cfg | sed -n -e 's/^log_file=//p')
tail -n500 "$nagios_log_file" &> "/usr/local/nagiosxi/var/components/profile/$folder/nagios-logs/nagios.txt"

Use Configure > Core Config Manager > CCM Admin > Core Configs to modify view the nagios.cfg, and retype this line. Save and apply changes then test the profile generator again.

Craig,

Retyping in CCM and saving does not solve the problem, but you set me on the right track by saying there might be extra characters! Here's what I found:

[root@nagiosxi ~]# nagios_log_file=$(cat /usr/local/nagios/etc/nagios.cfg | sed -n -e 's/^log_file=//p')
[root@nagiosxi ~]# echo $nagios_log_file
/usr/local/nagios/var/nagios.log

Adding 'cat -A' shows all characters:

[root@nagiosxi ~]# echo $nagios_log_file |cat -A
/usr/local/nagios/var/nagios.log^M$

[root@nagiosxi ~]# tail -n500 "$nagios_log_file"
tail: cannot open â/usr/local/nagios/var/nagios.log\râ for reading: No such file or directory

Looking at all Nagios configuration files.. It's not just nagios.cfg that is affected:

[root@nagiosxi ~]# file /usr/local/nagios/etc/*.cfg |grep -v "ASCII text$"
/usr/local/nagios/etc/cgi.cfg: ASCII text, with CRLF line terminators
/usr/local/nagios/etc/commands.cfg: UTF-8 Unicode text, with very long lines
/usr/local/nagios/etc/contacts.cfg: UTF-8 Unicode text
/usr/local/nagios/etc/nagios.cfg: ASCII text, with very long lines, with CRLF line terminators

Command dos2unix helped me getting rid of $ and ^M chars. You may lock this one, thanks!
