Windows NNTP Server (via NRPE)

Description

Monitors an NNTP Windows server using Nagios Remote Plugin Executor (NRPE). NRPE is used by the Nagios server to communicate with the Windows server. The nrpe.cfg file on the Windows server maps commands issued by the GroundWork server to scripts in the c:\nrpe_nt directory. Commands issued by this profile are installed with this package. If new NRPE commands are added, this file must be modified.

Profile Package

This package includes the following files:

  • Profile definition: service-profile-nrpe-nntp.xml

  • Plugin script: check_nrpe, check_nntp

  • NRPE script (installed on the monitored Windows server): nrpe_nt.zip

Installation

GroundWork Monitor includes many monitoring profiles for a variety of devices, systems and applications. Some profiles are pre-imported on a new GroundWork installation and others are distributed with the product. The configuration tool is used to import updated profiles and profiles that require additional setup, services can also be imported, see Importing Profiles.

Services Configuration

For plugin details you can run the service help command from within the nagios container. For example: Get to the nagios container from the gw8 directory: docker-compose exec -u 1000 nagios bash, then to the libexec directory: cd /usr/local/nagios/libexec, and enter a service help command e.g., ./check_snmp --help to receive help content.
