CDEFs in 8.x

[yid]

Since upgrading to 8.x, I haven't figured out anyway to do a lot of the CDEF funtions I used to.

For instance, I need to display the average user utilization, kernel utilization, and wait percentage across 4 cpus (I poll them seperately). With 6.x I just made a CDEF for each graph with the specific datasources that I needed.

There doesn't appear to be anyway to accomplish this in 8.x, tho. Will I have to set up a 6.x cacti instance for just these graphs?

TIA

The best way to reference data sources in a CDEF is to specify their location on the graph. For instance, if you have a graph with four items that you want to average together, a CDEF like the following would work:

Code: Select all

cdef=a,b,c,d,+,+,+,4,/

The data source name 'a' will always be the first data source on a graph, 'b' the second, and so on.
