| 8 | # This is a sample configuration file for the NRPE daemon. It needs to be |
|---|
| 9 | # located on the remote host that is running the NRPE daemon, not the host |
|---|
| 10 | # from which the check_nrpe client is being executed. |

|---|
| 181 | # command[<command_name>]=<command_line> |
|---|
| 182 | # |
|---|
| 183 | # When the daemon receives a request to return the results of <command_name> |
|---|
| 184 | # it will execute the command specified by the <command_line> argument. |
|---|
| 185 | # |
|---|
| 186 | # Unlike Nagios, the command line cannot contain macros - it must be |
|---|
| 187 | # typed exactly as it should be executed. |

| 189 | # Note: Any plugins that are used in the command lines must reside |

| 191 | # assume that you have plugins installed in a /usr/local/nagios/libexec |
