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.

# 95th percentile line

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.
