# <a id="snmp-manubulon-plugin-check-commands"></a> SNMP Manubulon Plugin Check Commands

The `SNMP Manubulon Plugin Check Commands` provide example configuration for plugin check
commands provided by the [SNMP Manubulon project](http://nagios.manubulon.com/index_snmp.html).

The SNMP manubulon plugin check commands assume that the global constant named `ManubulonPluginDir`
is set to the path where the Manubublon SNMP plugins are installed.

You can enable these plugin check commands by adding the following the include directive in your
configuration [icinga2.conf](5-configuring-icinga-2.md#icinga2-conf) file:

    include <manubulon>

## Checks by Host Type
