[rrd-users] About 95 percentile

[Firdous Saleheen]

Dear Concern,

Is there any function defined in RRDTOOL for calculating and displaying 95
percentile line?

If not what does the following highlighted line actually gives:

 

DEF:ds0=/home/rrdtool/data/router1.rrd:ds0:AVERAGE

    DEF:ds1=/home/rrdtool/data/router1.rrd:ds1:AVERAGE

    VDEF:ds0max=ds0,MAXIMUM

    VDEF:ds0avg=ds0,AVERAGE

    VDEF:ds0min=ds0,MINIMUM

    VDEF:ds0pct=ds0,95,PERCENT

    VDEF:ds1max=ds1,MAXIMUM

    VDEF:ds1avg=ds1,AVERAGE

    VDEF:ds1min=ds1,MINIMUM

    VDEF:ds1pct=ds1,95,PERCENT

 

the above lines are found from 

 

http://oss.oetiker.ch/rrdtool/doc/rrdgraph_examples.en.html

 

 

anyone who know the answer, can you let me know please?
