This monitor is part of the VMware integration provided in Provisiond. The monitor is specialized to test the health status provided from all Host System (host) sensor data.

This monitor is only executed if the host is in power state on.
This monitor requires to import hosts with Provisiond and the VMware import. OpenNMS HORIZON requires network access to VMware vCenter and the hosts. To get the sensor data the credentials from vmware-config.xml for the responsible vCenter is used. The following asset fields are filled from Provisiond and is provided by VMware import feature: VMware Management Server, VMware Managed Entity Type and the foreignId which contains an internal VMware vCenter Identifier.

The global health status is evaluated by testing all available host sensors and evaluating the state of each sensor. A sensor state could be represented as the following:

  • Unknown(0)

  • OK(5)

  • Degraded/Warning(10)

  • Minor failure(15)

  • Major failure(20)

  • Critical failure(25)

  • Non-recoverable error(30)

The service is up if all sensors have the status OK(5). If any sensor gives another status then OK(5) the service is marked as down. The monitor error reason contains a list of all sensors which not returned status OK(5).

In case of using Distributed Power Management the standBy state forces a service down. The health status is gathrered with a direct connection to the host and in stand by this connection is unavailable and the service is down. To deal with stand by states, the configuration ignoreStandBy can be used. In case of a stand by state, the service is considered as up.

state can be changed see the ignoreStandBy configuration parameter.

Some example configuration how to configure the monitor in the poller-configuration.xml.

<service name="VMwareCim-HostSystem" interval="300000" user-defined="false" status="on">
  <parameter key="retry" value="2"/>
  <parameter key="timeout" value="3000"/>

<monitor service="VMwareCim-HostSystem" class-name="org.opennms.netmgt.poller.monitors.VmwareCimMonitor"/>
