Hi,

We do server monitoring with NCPA, but after adding CPU's to our server, the graph data stopped after that.
The test is running fine, but at the time adding CPU's the graph is empty.

The avg CPU is fine, it's only the following test:

check_ncpa.py -M cpu/percent -w '80' -c '90' (left out some parameters for security reasons)

I believe it's because the amount of CPU's has changed, but would be nice to fill the graph again without losing historical data.

Thank you.

graph is still empty from the day we added more CPU's, please provide me a solution.

Thank you.

Your analysis is correct. Check out https://support.nagios.com/kb/article/n ... g-149.html which has a script to search out rrd files(responsible for holding the information for each CPU to be graphed) and correct them.
