The reason you were not notified is because you copied the localhost checks, which run on the Nagios server itself. You need to run remote checks through something like NRPE: https://assets.nagios.com/downloads/nag ... g_NRPE.pdf

I believe I already have nrpe installed on the remote host. Did that durning the install the linux agent ./fullinstall
Do I edit the service for the hosts and then click on Managed Templetes? Which templete would I select. I know it had localhost .

Since this is already installed I believe I need to change the service for duey "Service Status - httpd" manage templete to something else.
Should I change it to this to "xiwizard_nrpe_service" If not what do I change it to? Please advise.

That did not work. When I run the "Run Check Command" the output is the nagios server not the remote see below. I need it on the duey server which is a remote hosts

Code: Select all

Re: Check DB instance

Post by donnyforbes »

Here is what I did... I change the check command to ->

check_nrpe
$USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
$ARG1$ httpd

Then ran the "Run check command" put the ip_address in of the remote server see below.

Run Check Command
Host Address: 192.168.1.43
Run Check Command

[nagios@nag ~]$ /usr/local/nagios/libexec/check_nrpe -H 192.168.1.43 -t 30 -c httpd
NRPE: Command 'httpd' not defined

Is this how I get this to work?
