Hello All,

I have installed nagios in two of our RHEL 6.9 servers, one is working fine, but getting the error "Unable to get process status" in one of the server.

While checking the hosts and servers, its showing the bellow error message,

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.
-----------------------------------------------------------------------------------------
Please contact the server administrator, name@Domain and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Apache/2.2.15 (CentOS) Server at 10.127.184.7 Port 80
------------------------------------------------------------------------------------------------

I have followed the guid - "https://www.tecmint.com/install-nagios-in-linux/" to install in both the servers

Please find the bellow output from error log and service log

Can you share the suexec log from the problematic machine? And if it's complaining about a specific path, the output of ls -al against that path.

Also the outputs of these commands:

Code: Select all

groups nagios
groups apache
cut -d: -f1 /etc/group | grep 'nag\|apa\|htt'

Thanks @mcapra!

@Rajan_8, Let us know your suexec log and the output from @mcapras suggested commands.

I would follow this guide as it is regularly tested.
