95th Percentile AVERAGE and MAX

[div8cn]

I found that template Interface - Traffic (bits/sec, 95th Percentile) uses the value of AVERAGE to calculate 95th Percentile. This data is different from the ISP data.


Can it use the value of MAX to calculate the 95th Percentile?

There are 4 data in the data source AVERAGE, MIN, MAX, LAST

Template:
Interface - Traffic (bits/sec, 95th Percentile)

What Cacti version?

[div8cn]

Cacti Version 1.2.2

[TheWitness]

I'm pretty sure if you read the documentation on this, the answer is yes. But it may hove not worked so well on an older Cacti like that. A good review of the ChangeLog should be in order. Right now 1.2.23 is very stable, but don't import the packages. We'll fix that on 1.2.24 to be released next month.
