95th percentile counted wrong

[twindh]

Hi!

My 95th percentile graph is not counting it right. It's about half of the real value.
Example graphs:

Here you see the trend before the bad calculation showed up:

Compare to Cacti which shows the right 95th value:

Let me know if any more information is needed.

Hi @laf

They are from:

I can't duplicate this, both my home and work installs seem to show the correct values.

This is still causing a lot of billing troubles for us. Is there any update on this?
Let me know if you need any debug data and I'll provide it.

Another issue we have seen is zero bytes 95th:

Not sure if this is related to #3524 ?

Issue was due to wrong snmp ifspeed reporting. The billing-poll limits the data to the ifspeed. His ports were reporting 1G and the bills all flatline at 1G. Once changed to 10G the bills got the correct data accounted.
