Troubleshooting Server Monitoring

• When server monitoring is done from remote machine, both the machines should have WMI (Windows Management Instrumentation Service) and RPC (Remote Procedure Call) running. Generally in most of the windows machines both of these services will be running by default. In some machines, if any of the services (WMI service or RPC server is not running) or if the administrator has enabled the firewall then WMI API will not be able to contact the remote machine and collect data from the same. To check whether WMI and RPC server are running, type the following commands:

• net start - This will list all the services currently running in your machine. Check whether Windows Management Instrumentation and Remote Procedure Call is listed.

• If not, type: net start winmgmt from the command prompt. This will start the WMI service. To start RPC server, type: net start rpcss from the command prompt. This will start the RPC server.

• To check whether firewall is enabled or not (applicable only for remote machine):

• Open Control Panel and choose Windows Firewall. In the Windows Firewall screen, select the General tab. Check which radio button is checked On or Off. If On is selected this means that the firewall is enabled. If Off is selected this means that the firewall is disabled (then there is no issue).

• If firewall is enabled i.e., if On radio button is selected then you need to open out the ports specific to WMI to collect data from the remote or local machine. To do this, type: netsh firewall set service RemoteAdmin in your command prompt.

• Now run the load test case that includes the server monitoring to view the test results.
