Nagios System Problem

[kenntun]

After I restart nagios services, XI System Component Status got Monitoring Engine Status Error

I click on error, it prompt "nagios.lock" not find.

I ssh the server and find nagios.lock are existing

How to fix it?

Hello and welcome to the forum!

What version of Nagios XI are you running?

Can you also show the output of the following commands:

Code: Select all

ps -ef|grep nagios.cfg
ll /var/run/nagios.lock
grep nag /etc/group
chage -l nagios

The problem seems hit by the following httpd configuration

ServerTokens Prod
ServerSignature On
FileETag None
TraceEnable off
Header always append X-Frame-Options SAMEORIGIN
Header set X-XSS-Protection "1; mode=block"
RewriteEngine On
RewriteCond %{THE_REQUEST} !HTTP/1.1$
RewriteRule .* - [F]

After I comment out the following configuration
problem resolved

##RewriteEngine On
##RewriteCond %{THE_REQUEST} !HTTP/1.1$
##RewriteRule .* - [F]


Any idea??

What was this configuration attempting to do?

To disable un-used HTTP Protocol after our security teams perform security scanning on nagios

It appears you were likely rewriting the JS calls to the backend to get the status.
