It's mid August and everyone in the northern hemisphere is away on holidays. Well, almost everyone. As there's never a pause for the IT infrastructure of a company, also admins have to keep on working. To make your stay at work worthwhile, or to at least provide some travel literature if you're actually away, here's our newest "Sensor of the Week"—the WMI Service sensor.

PRTG uses Windows Management Instrumentation (WMI), Microsoft's base technology for monitoring and managing Windows based systems, to access data from various Windows configuration parameters and status values. The WMI Service sensor uses this approach to:

  • Check if a service is running,
  • Start/restart services automatically, if the monitored service is not running when scanning the device, and
  • Monitor extended values, for example, CPU and pagefile usage, the number of handles and threads, and the working set of the monitored service.


If you're responsible for Windows servers, be it web servers, SQL servers, or Exchange servers, you should definitely give the WMI Service sensor a try! It can help you streamline your workflow and gain a better overview of all services that should be up and running.

Do you want to know more? Please have a look at the PRTG manual and find a comprehensive description of the WMI Service sensor.
