CPU Ready value is cumulative between the number of vCPUs the VM is assigned. For example, a one vCPU VM has the measurement of 1000ms. For a VM with two vCPUs, the same performance drop would rise to 2000ms, or 1000ms per vCPU. For a VM with four vCPUs, it would be 4000ms.
CPU Ready / (interval * 1000) * 100 = Performance Penalty
Statistics Rollup Intervals
vCenter defines the following default intervals for rollups:
- Real-Time: 20s interval (20 seconds)
- CPU Ready / (20 * 1000) * 100
- Daily: 5m interval (300 seconds)
- CPU Ready / (300 * 1000) * 100
- Past Week: 30m interval (1800 seconds)
- CPU Ready / (1800 * 1000) * 100
- Past Month: 2h interval
- CPU Ready / (7200 * 1000) * 100
- Past Year: 1d interval
- CPU Ready / (86400 * 1000) * 100
Real World Examples
Here is a Database server real-time graph. The average CPU Ready is 609.
609 / 22000 * 100 = 2.76% CPU Ready
On this particular DB server, it was configured with 8vCPU.
After reducing the vCPU from 8 to 4, I used the next available day to review performance improvement (or not).
I can see now that my average is 7420ms, or 2.76% performance degredation. Performance improvement of almost 45%!
When generating reports in OpManager v11 and exporting as PDF, the footer contains ManageEngine OpManager Page : as the footer.
To change this, on your OpManager install, navigate to the installation path of OpManager and modify confrandProps.properties file. Add the following line, and customize accordingly.

You do not need quotes surrounding the pdfFooterText variable.
Save the file and go generate a report and export to PDF. Enjoy!
When browsing my Downloads folder, or any folder in general, on Windows 10 I have experienced the Working on it… message and it takes a few seconds to load. This doesn’t matter if I have a lot of files/folders or just a few, it still hangs.
Open Folder Options > Set Open File Explorer to This PC. Try WinKey + E now.
If it opens fine, then problem is with Quick access cache, which can be cleared by deleting
*.automaticDestinations-ms from the following directory, using Command Prompt.
