Um Windows Systeme zu überwachen, kann man sich der check_mk_agent.exe von Matthias Kettner bedienen. Das Windows Binary befindet sich in der OMD Instanz unter /omd/versions/{version}/share/check_mk/agents/windows.

Installing the Agent manually

The check_mk agent for Linux consists of only two files: a shell skript called check_mk_agent.linux and a configuration file for xinetd.conf, both of which can be found in the subdirectory agents. xinetd is an improved version of the classical inetd and a is available or even standard on most current linux distributions.
Alternatively you can use the classical inetd, but this documentation focusses on xinetd.
Please install the file check_mk_agent.linux on your target host as /usr/bin/check_mk_agent (drop the .linux). You should be able to execute the agent simply by calling it from the command line. It can be run as non-root user, but some diagnostic information can only be retrieved if it is run as root. The output of check_mk_agentlooks like this (abbreviated):

In Verzeichnis mit agents wechseln
cd /opt/omd/versions/1.20/share/check_mk/agents

cd ..

scp -r agents root@192.168.1.81:/tmp/

cp check_mk_agent.linux /usr/bin/check_mk_agent 

Test:

[root@localhost agents]#  check_mk_agent

Version: 1.2.4p5

AgentOS: linux

PluginsDirectory: /usr/lib/check_mk_agent/plugins

LocalDirectory: /usr/lib/check_mk_agent/local

SpoolDirectory: /etc/check_mk/spool

AgentDirectory: /etc/check_mk

You should also install the file waitmax on your target host as e.g. /usr/bin/waitmax. This file is not mandatory, but really needed by the agent code of some checks like the nfsmounts, ipmi_sensors, ntpq, nvidia and cups_queues.

cp waitmax /usr/bin/waitmax

The configuration of Xinetd is simple: Copy the file xinetd.conf into /etc/xinetd.d and rename it do check_mk:

cp xinetd.conf /etc/xinetd.d/check_mk
