CDEF-function for reverse percents

[alibek]

Text automatically translated, sorry for the clumsy text.

There is a data source that returns the parameter cpuIdle (from 99 to 1).
Want to display the graph utilization CPU (formula "100-cpuIdle").
Use next CDEF-function:

Code: Select all

cdef = CURRENT_DATA_SOURCE, UN, UNKN, 100, CURRENT_DATA_SOURCE, -, IF

However, the schedule is displayed incorrectly, displays 100%.
What is wrong with this formula?

[gandalf]

please remove the blanks. I'm not sure whether cacti does this. RRDTool does not accepts blanks in CDEFs
R.

Sorry.
The spaces were inserted in the copy-paste, in fact they are not.
Formula is:

Code: Select all

cdef=CURRENT_DATA_SOURCE,UN,UNKN,100,CURRENT_DATA_SOURCE,-,IF

Debug output is:

Code: Select all
