Hi @manikanta,

Welcome to the Nagios Community Forum.

Let's see, are you using an agent? If you're using NRPE, take a look at our KB article for help troubleshooting.

Also, make sure you can run the plugin locally as the nagios user. It could be permissions on the plugin or the command is not defined in npre.cfg.

Let us know what you find out.
