Monitored Parameters

Microsoft .NET is monitored based on the attributes such as Heap Size, Threads etc. Data collection happens through WMI. The monitoring details of Microsoft .Net are represented graphically and that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored by the .Net, based on these details.

  • Availability tab gives the Availability history for the past 24 hours or 30 days.
