Nagios Issue

[glennbtn]

Hi All

I have Nagios installed on a server with a number of ubuntu servers running NRPE. I have a few different scripts running with no issues except for 1 that needs to check mysql replication on the slave machine.

If I run the file directly on the host machine
/usr/local/nagios/libexec/check-mysql-slave.pl

I get the correct responce
OK - Waiting for master to send event, replicating host xx.xx.xx.xx:3306

When I run this using the NRPE check
/usr/local/nagios/libexec/check_nrpe -H localhost -c check-mysql-replication

I get NRPE: Unable to read output

I have the users on the file set as nagios as I should and I have the file set with the correct permissions

Can anyone shed anylight here on what I am doing wrong

Thanks

Hi Glennbtn,
Check if the port 5666 is open in your localhost. You can check this way netstat -at |grep nrpe.

Thanks for a reply Sumit

Yes I have configured port 5666. I have other scripts checking memory etc which are all working fine, it's just this 1 script that when run with nrpe does not work.

Thanks

Hi Glennbtn,
If you are not running the command from root then please try to run it as
sudo /usr/local/nagios/libexec/check_nrpe -H localhost -c check-mysql-replication

Hi Glenn,
Please let me know how did you ran the command. I mean are you running it from root or you are running it as sudo user. Also try to run the command a the root user.

I ran the command as both root and the nagios users. Both give the same NRPE result

Both will run the manual .pl script file with the correct results

Thanks
