Dear Alex .... First i have to thank you for your responce and for your time spending for my problem.

These values can be *very* high, such as terabytes per second. >> If you suffer from this, don't try to work around the problem but >> solve the problem. I am not using RRDTOOL for routers/switches/SNMP-enabled-devices monitoring.. I am using RRDTOOL to plot time values as GAUGE. e.g I request a DNS entry and then i plot the responce time. It could take from 3 millisecs to 4000 millisecs etc etc. That means there is no MAX for my values ;-( BTW ... Thank you for your script advice... > However: How do you know that the 95th percentile doesn't result > in another high value? Actualy I dont.. But my expirence said that.. i saw the plots and with this percentile i can drop all this high values from all of my plots Another algorithm i am thinkig is the folowing LIMIT=(AVERAGE+60) Is it possible ??? Is it correct the folowing command ?? CDEF:V=value,0,AVERAGE,150,+,LIMIT And a last question/wish to Tobi... I have read the mailing list and i saw there is a need for persentile support.. While it is imposible to do that with CDEF/RPN and i have to write a script to calculate this is it possible to add this function native in a next version of RRDTOOL??? Nikos Katsifos p.s.
