.NET Framework monitoring and management plugin

Verax NMS Microsoft .NET Framework management plugin enables easy monitoring, alerting, health check, management and performance reporting for any .NET applications. The plugin supports versions 2.0 and higher of the Microsoft .NET Framework. The communication between the NMS server and managed framework instance takes place using WMI (Windows Management Instrumentation) protocol. For more information on monitoring of the .NET framework please refer to: http://msdn.microsoft.com/en-us/library/w8f5kw2e.aspx.

General information view

The view presents general .NET Framework information such as:

• Installed software version
• Number of exceptions thrown by all applications since the .NET Framework instance has been started
• Number of JIT (just-in-time) compiler failures
• Number of running applications
• Number of physical and logical threads
• Number of classes loaded and failed classes
• Number of security checks performed
• Memory usage: total (all applications) heap data usage, amount of committed and reserved data
• Network usage: amount of data sent, amount of data received and number of network connections used by all applications

Memory view

The view displays a detailed memory usage for each running .NET application, including:

• Allocated bytes per second
• Finalization survivors
