Setup and Use
A new settings tab labelled 'WMI Tracking' is available (Console -> Configuration -> Settings -> WMI Tracking).
3 Fields require populating:
- Username - Account that will be used for the WMI Queries
- Password - Password for the above account
- Target Host Names - A comma separated list of the devices you want to track.
A new tab is available at the top of Cacti labelled 'WMITrack'.
Clicking this will show you an interactive table with details on your tracked devices.
The table columns can be sorted and filtered by various criterias.
Clicking on a row will display the message of the last System Error as reported in Event Viewer.
Data in the table is updated every 60 seconds - just keep in mind your poller is probably running every 5 minutes.
Some inner working notes that aren't important to know:
When a target is added to the list it is allocated a random number from 0 - 11.
Every Cacti poll initiates the WMITrack tool to query all devices that match the current cycle number.
The cycle number increments by 1 every time it runs, resetting itself to 0 once it is greater than 11.
If your Cacti polling service runs every 5 minutes it should have executed 12 times within an hour.
Having WMITack cycle from 0 - 11 balances it so devices are scanned once an hour.
It could take up to an hour before any results are collected and displayed.
Removed devices are also purged during the polling process.
