I would like to see the 95th Percentile statistic for a time period.
The only metric I've found is that for some prebuilt trending graphs. And that's for each resolution rather than the overall period.
Either in as a column/attribute in the custom tables, as a option for a horizontal line in trending graphs, or a threshold line what Capcity Planning in NFA does.
In any case, I would like some way to identify sites that have high/large spikes which cause network degration, but low overall averages. And does not have the fault of deviations where we may see huge numbers for very low volume increases (ie 1%->5%).
