Performance Counters
Performance Counters
The MindLink Server exposes a custom suite of Windows performance counters that can be used to monitor the usage and health of the system. The performance counter suite can be used to indicate general usage statistics as well as to detect outages or other problems, via the number and rate of errors thrown.
Saving the management tool automatically adds the service account to the local Performance Logs Users group.
In addition, the MindLink server is a .NET service and hence exposes the standard suite of .NET performance counters. It is recommended to monitor at least the standard Windows memory usage and CPU performance counters, as well as the MindLink performance counters that report error rates, as a general indication of service health.
The category in which the MindLink performance counters are found is called 'CollaborationFoundation'.
Tools such as Microsoft's Performance Monitor (perfmon.exe) can be used to view the value of the counter and generate reports. A performance counter can be added by clicking the green plus icon in the performance monitor.
The collaboration foundation entry has a dropdown which contains the performance counters.
Select the performance counter needed and then select the instance of the object, click 'Add' and then confirm by clicking 'OK'.
Below is an example of how the performance counter appears in the performance monitor when selected.
Please note, to view Performance Counters from a remote computer the Performance Logs and Alerts firewall exception must be enabled on the remote computer.
