7.6 Unable To Start ASM Performance Monitor Server Service
Issue:
ASM Performance Monitor uses Windows Performance Counter for its internal performance
measurement. If you cannot start the ASM Performance Monitor Server Service, this could be due
to the fact that ASM Performance Monitor cannot load the performance counter and therefore is not
able to collect or interpret the data from the Windows Performance Counter. This could happen if
the installation was not done properly or is done without the appropriate permissions.
► In this case, perform the steps below:
1. Select Control Panel, – Administrative Tools – Computer Management.
2. Expand the Computer Management – System Tools – Event Viewer – Windows Logs –
Application options.
The Windows Performance Counter can be identified as the source of the issue from the error
event log as displayed in the following dialog.
