This option only alternatively computes Y axis. This option is relatively new and was not in older RRDTool versions.

[rrd-users] How to make CDEF compute a bunch of moving averages ?
Hi, I've a rrd file that has only 1 data source where its CF is defined as average. I'm trying to go back to a particular week in last month and compute a bunch of moving averages for that week. Each moving ave should be computed on samples from the last 15 days. Is this even possible in using CDEF ? Or I need to do this programmatically using 'rrdtool fetch' ? Thx. Thanks. ;-e). -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdminhttp://www.ee.ethz.ch/~slist/lsg2.cgi
[rrd-users] help with graph issue
Hi I have manages to succesfully graph some captured data and got RRDTool to do exactly what I want. But would like the graphs it produces to be filled in below , like MRTG graphs are. I thought the setting '--alt-y-mrtg' did that but I seem to get an error when thats placed in the 'rrdtool graph' command line. Any help would be much appreciated.

Should be as simple as: DEF:a=a.rrd:ds0:AVERAGE DEF:b=b.rrd:ds0:AVERAGE CDEF:avg=a,b,+,2,/ AREA:avg#FF:average of a and b Serge. - Op de inhoud van dit e-mailbericht en de daaraan gehechte bijlagen is de inhoud van de volgende disclaimer van toepassing: http://www.zeelandnet.nl/disclaimer.php -- Unsubscribe mailto:[EMAIL PROTECTED] Helpmailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdminhttp://www.ee.ethz.ch/~slist/lsg2.cgi

You can't access RRD files using "CDEF". Accessing original data is done using "DEF". When you have access to the data, so when it is in a "vname" (DEF:vname=) you can process it using "CDEF".

You probably don't want that. 2. Why do you use absolute? You probably want to use gauge. 3. 24 samples of 300 seconds does not make 24 hours. 4. --lower-limit, --upper-limit and --rigid will help you to fix your y-axis. 5. your numbers will get interpolated unless $date div 300 == 0. May not be a problem, as long as you know.

[rrd-users] Can CDEF be made to compute averages from 2 different data sources ?
Hi, I've 2 different data sources from 2 separate RRD files. Both heartbeats are the same, and the 'step' for both RRD files are the same. Is it possible to write a CDEF to compute the average of some of the samples from these 2 data sources and then graph this average value ? By 'some samples', I mean samples from a certain period of time in the past. By looking at the manpages of 'rrdtool graph', I can't see how this can be done via CDEF... or am I misusing CDEF or missing the point of CDEF ?

[rrd-users] Re: My firs rrd - please help :)
I had this problem in the week.
I was told to use
--lower-limit 1 --upper-limit 500 for the y-axis.
To measure over a 25 hour period I would sugesst taking 288 samplesI
think that works out as 1 sample every 300 seconds (i.e.5 minutes).
something along the lines off :
/usr/bin/rrdtool create file.rrd --start 'epoch time'
BDS:numbers:GAUGE:600:U:U RRA:A
VERAGE:0.5:1:288
Hope this helps.
