Hi,

We are using custom plugin to monitor oracle db instance. Plugin is running as expected with out any errors.

How ever running under Nrpe it throws error:

Code: Select all

CHECK_NRPE: No output returned from daemon.

Not sure, what is causing the issue.

Kindly help in fixing this

Thanks
Anish

Take a look at the NRPE Troubleshooting guide at the link below for the error you are having when the check is run.
https://assets.nagios.com/downloads/nag ... utions.pdf

When the NRPE agent runs a check, it runs it as the nagios user and if that user cannot run the plugin, it will cause the error you are receiving.
Login to the remote system and run the command as the nagios user and adjust the permissions of the files / folders as needed.
