Nagios Support Forum

Hi all,

Hoping for some help.

I'm migrating my install of nagios from a virtual machine onto a physical machine.

The old server is Centos Based and is working correctly. I've had no issues with this.

The new machine is rasbian based (debian on a raspberry pi)

I've copied the configs over and made sure they were correct but on the new machine i get the following output

"No output returned from plugin"

this error comes back on the following:

cpu load
current users
uptime
various disk checks. - check_sda1 - sde1

all apart from the disk checks are common commands. the disk checks are referenced within the nrpe.cfg file on the remote server.

From the new server, if i call the following from the command line i get a response.

./check_nrpe -H 192.168.1.85 -c check_sda1

I have other checks that are working without any issues but i believe all but one are external checks. The other internal one i believe is the check_apt one.

Does anyone have any ideas why this might be failing to communicate?

Thanks

Can you show us your server and command definition for the Nagios server's side? That way we can verify Nagios is querying the NRPE agent properly. Are you using SSL?
