No data in Site24x7 web client

Troubleshooting steps when CPU, memory, or disk usage shows no data in the Site24x7 web client

If all you see is a dash under the CPU utilization, memory utilization, or disk utilization graphs in the Site24x7 web client, it could be an issue with the WMI query.* 

To troubleshoot:  
  1. Open the Run terminal and execute the command wbemtest.

  2. Click Connect.

  3. In the Namespace field, enter root\cimv2 and click Connect.

  4. Click  Query.

  5. Enter the query in the given text box and click Apply.

For CPU utilization, execute the following queries:
  1. select PercentProcessorTime from Win32_PerfFormattedData_Counters_ProcessorInformation - For Windows Server 2008 R2 and above
  2. select PercentProcessorTime from Win32_PerfFormattedData_PerfOS_Processor - For versions before Windows Server 2008 R2

For memory utilization, execute the following query:
  1. Select FreePhysicalMemory,FreeVirtualMemory,TotalVirtualMemorySize,TotalVisibleMemorySize from Win32_OperatingSystem

For disk utilization, execute the following query:
  1. Select Name, Size, FreeSpace, DriveType, FileSystem, MediaType from Win32_LogicalDisk where DriveType=3



   


  6. Check for the query result in the window that opens. If there is any discrepancy, check if the related WMI counters are working properly or if the WMI is corrupted.
