The WMI Plugin provides data collection services for devices that support the WMI protocol. It operates asyncrhonously to the Cacti data collection and stores the resulting information into cache tables. These cache tables can then be used to generate graphs, thresholds and alerts. It relies on the 'wmic' command in Linux, and WMI services via Microsofts COM protocol from Windows Cacti servers.
This plugin is NOT fully functional. It should not be used on production systems. Use at your own risk!
To install the plugin, simply copy the plugin_wmi directory to Cacti's plugins directory and rename it to simply 'wmi'. Once this is complete, goto Cacti's Plugin Management section, and Install and Enable the plugin. Once this is complete, you can start to define WMI queries for your Windows and other Device Templates that support WMI.
Make certain that you install the wmic binary if you are planning on running on Linux.
The WMI plugin allows you to define multiple Queries, and then associate those queries with Cacti Device Templates. Therefore, if you have a generic Windows Device Template, you can add those queries that are significant for a general Windows device. If you have a Microsoft SQL Server Device Template, you can add WMI Queries that are specific to Windows SQL Server there.
There is presently only one setting support in the WMI plugin, and that is to Autocreate the actual WMI polling at device creation or update based upon the WMI Queries defined as a part of the Device Template. This setting can be found under Settings -> Device Defaults.
The wmi plugin has been was developed several years ago but never actually finished. This release formalizes it's behavior and provides a new level of scalability to Cacti when gathering data from WMI compatible device's.
