Detecting with Capsd

First configure $OPENNMS_HOME/etc/capsd-configuration.xml to detect the services on your Windows machines. The setup use the integrated Win32ServicePlugin:

 
  <!-- Windows Standard -->
  <protocol-plugin protocol="Server"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">
      <property key="timeout" value="2000" />
      <property key="retry" value="1" />
      <property key="service-name" value="Server" />
  </protocol-plugin>
  <protocol-plugin protocol="Terminaldienste"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">
      <property key="timeout" value="2000" />
      <property key="retry" value="1" />
      <property key="service-name" value="Terminaldienste" />
  </protocol-plugin>
  <protocol-plugin protocol="Terminal-Services"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">

      <property key="retry" value="1" />
      <property key="service-name" value="Terminal Services" />
  </protocol-plugin>
  <protocol-plugin protocol="Print-Spooler"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">
      <property key="timeout" value="2000" />
      <property key="retry" value="1" />
      <property key="service-name" value="Print Spooler" />
  </protocol-plugin>
  <protocol-plugin protocol="Druckwarteschlange"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">

  </protocol-plugin>
  <protocol-plugin protocol="RDP"

      <property key="port" value="3389" />
      <property key="timeout" value="3000" />

  </protocol-plugin>

  <!-- Microsoft Active Directory Services -->
  <protocol-plugin protocol="WINS-Server"

    scan="on" user-defined="false">
      <property key="timeout" value="2000" />
      <property key="retry" value="1" />
      <property key="service-name" value="WINS" />
  </protocol-plugin>
  <protocol-plugin protocol="Dateireplikationsdienst"
    class-name="org.opennms.netmgt.capsd.plugins.Win32ServicePlugin"
    scan="on" user-defined="false">
      <property key="timeout" value="2000" />
      <property key="retry" value="1" />
      <property key="service-name" value="Dateireplikationsdienst" />
  </protocol-plugin>

  <!-- Microsoft IIS-Services -->
  <protocol-plugin protocol="WWW-Publishingdienst"

      <property key="retry" value="1" />
      <property key="service-name" value="HTTP-SSL" />
  </protocol-plugin>
  

Monitoring the services

To monitor the service state add the following lines to your $OPENNMS_HOME/etc/poller-configuration.xml:

Change your timeouts and retry settings to your needs, I have some heavy load machines and on with higher timeouts and more retries I have a lot less 30 second outages.
