Rate per variable unit of time

[digrich]

@johann8384 This feature is good to have. We have many metrics where data is not changing that frequent and we are interested to see the rate of change per /min/hour/day.

In openTSDB, do we have support to do the downsampling after rate of change calculation?

Any work done on this feature request. I also want similar functionality. What kind of effort would be required for this feature in case i take up the implementation.

[abhichandel]

I just completed teh implementation of this. This seems to be more of downsampling on the difference between two datapoints. I am not sure if it should be addressed as rate. In the current implementation on next branch I changed rate options to be as [counter,max,reset,interval] but the implemenation is exactly as of downsampling.
If the interval is not specified then the default interval is 1 ms but if granularity of data is to a minute then the rate (downsampling of diff) would be per minute.
Please let me know your inputs.

@abhichandel is this feature implemented?

[johann8384]

It doesn't appear to be, just based on a quick scan of the PR comments.
