System Health Counters Display "Unavailable" in WebMonitor
 

Product: ModusMail & ModusGate

Version & Build: 4.3

 

 

The System Activity gauges in the System Health screens acquire their information from the Performance Monitor counters. If any of the gauges display an "unavailable" warning message, it is possible that the counter has been disabled.

 

Troubleshooting the problem:

 

  • Check the WebMonitor error logs to find the specific counter name being used
    • Go to ...Vircom\Web\WebMonitor\Log, open the yyyymmdd_Error.log file and search for an entry similar to the following:

Source: /WebMonitor/SystemHealth/getUpdate.aspx
Code: 0xC0000BB8
Facility: 0x1B
Details:
Error while reading performance counter data.
Error while reading performance counter data.
param 0='\POP3S\Active Connections'
param 1=
param 2=

 

  • In this example, the error points to a problem reading the Performance Monitor counter POP3S > Active Connections
    • Open Performance Monitor and enable the POP3S > Active Connections counter to see if there is any activity
  • If the counter does not appear in the Performance Monitor list, it may be disabled in the registry
    • Open the Registry Editor and go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\<specific service name>\Performance
    • Locate the DisablePerformanceCounters key with a value of 1 (i.e.  On)
    • Set the value to 0 (Off)
    • Stop and start the Monitor service
