Any way to monitor whether or not nagios is up on another co

Anyone happen to have a command to do this?

Thanks

what about an snmp script? or a check_http looking for the “whooops! nagios is not running” webpage…

Use check_procs on the remote computer and have it send the check results via nsca to the central nagios server as a passive check.

define service{
use generic-service
host_name test
service_description Nagios-Is-Running
check_command check_procs2!1:6!"/export/home/nagios/bin/nagios -d /export/home/nagios/etc/nagios.cfg"

‘check_procs2’ command definition

define command{
command_name check_procs2
command_line $USER1$/check_procs -c $ARG1$ -a $ARG2$
}

I aplogize for my ignorance first and foremost.

Suppose computer A wants to check if computer B is running nagios.
Should this change of the config file happen to A, B or both?

I added this to computer A, and get this warning on the site:
System call sent warnings to stderr

define service{ use generic-service host_name ComputerB service_description Nagios-Is-Running check_command check_procs2!1:6!"/usr/local/nagios/bin/nagios -d /usr/local/nagios/nagios.cfg"

‘check_procs2’ command definition

define command{
command_name check_procs2
command_line $USER1$/check_procs -c $ARG1$ -a $ARG2$
}

First, type
/usr/local/nagios/libexec/check_procs --help
You will notice, that there is NO PLACE to make an entry for a remote host, so it would be impossible to use this, and many other plugins like this one, to make checks on remote hosts.

If you are running nagios on computer A and B, then please do as instructed in my first reply. Perform the check on computer B’s nagios setup, and pass the information to Computer A as a passive check.
