Custom Poller, Counters and Transforms

sero2k

Hi There,

I have a custom counter poller that monitors the number of bytes. This is a value that steadily increases over time.

The poller runs once every minute and the graphs correctly show the difference in the bytes since the previous poll. This creates a graph in Bytes per Minute. What im trying to do is use a transform to change this so the graph shows in kbps per second. However, when I apply a transform to the poller it seems to apply it to the raw value and not the delta between the previous and current poller value.

Rather than a kpbs per second graph I get a graph total bits transferred that steadily increase over time.

For example

Raw value at poll #1 is 200

Raw value at poll #2 is 500

The custom poller graph will show 300 (delta) but the transform will show 500 (and just steadily increases)

Here is the transform formula to convert the bytes per minute to bps.

({CUSTOM_POLLER}*8)/60

 Any ideas how i can get the transform to apply to the delta value?

 

Hope this makes sense!

Thanks

OK - Reading another post I know understand that when using a counter it automatically calculates the delta to per second. So I dont need to have this in the transform. However, I still need the graph to display in bits per second and not bytes per second. Does anyone know how I could do this?

Many Thanks
