Hey guys, as a service provider the 95th percentile number is huge in our world. How have you guys been able to show that number. This is usually looking at interface traffic.

Hi asmithzim,

Where and what do you mean exactly?

You can adjust all limits.

The 95% line is only available if your graph is generated with PNP4Nagios.

If you use the enterprise edition, then it is not possible to draw such a line.

The function used inside the PNP4Nagios is the following - taken from rrdtool manual

https://oss.oetiker.ch/rrdtool/doc/rrdgraph_rpn.en.html

PERCENT, PERCENTNAN

This should follow a **DEF** or **CDEF** *vname* . The *vname* is popped, another number is popped which is a certain percentage (0…100). The data set is then sorted and the value returned is chosen such that *percentage* percent of the values is lower or equal than the result. For PERCENTNAN *Unknown* values are ignored, but for PERCENT *Unknown* values are considered lower than any finite number for this purpose so if this operator returns an *unknown* you have quite a lot of them in your data. **Inf** inite numbers are lesser, or more, than the finite numbers and are always more than the *Unknown* numbers. (NaN < -INF < finite values < INF)

Example: `VDEF:perc95=mydata,95,PERCENT`

`VDEF:percnan95=mydata,95,PERCENTNAN`

The Percentile line is back in CEE graphs. But only in custom graphs as a transformation of a metric, it is currently now built into the standard graphs of e.g. Interface checks.
