Kid Control seems to be way to go.
After some testing and making a new dashboard in Splunk, I do get the same data and same graphs as I do get from IP accounting.
If I do not find any other big bug or other problem, this will be released in the next version of MikroTik for Splunk.
Then we do have a working version for Router OS 7.x
One negative thing is that script needs to be updated to collect these data, so If you have many routers, all needs to be update.
Here is a sample graph. (See the missing bottom graph compare to the IP Accounting)
