NRDP - Passive Host And Service Definitions

Overview

Once your Nagios service is receiving Passive NRDP checks, they will not appear anywhere in Nagios until you define host and service definitions.

The following definitions compliment the guides for using NCPA to send passive check results to Nagios via NRDP.

The following Nagios Definitions will result in:

• A Passive Host object for the server S1601

• Passive Service objects for the server S1601 for the services:

  • CPU Usage

  • Disk Usage

  • Swap Usage

  • Memory Usage

  • Process Count

Which will result in something like this in Nagios:

Command

define command {
    command_name            check_dummy
    command_line            $USER1$/check_dummy $ARG1$
}
