Hi,

The trick to do this is to use avgif function that allow you to include in the average calculation only values in the right range. The crux is that you have to calculate the range beforehand.

Here is an example using the Perf table:

let CounterP95=toscalar(
    Perf
    | where CounterName == "% Free Space"
    | summarize percentile( CounterValue, 95)
    );
Perf
| where CounterName == "% Free Space"
| summarize avgif(CounterValue,CounterValue<CounterP95)

Hope it helps,

Meir :->
