Hi everyone!
I guess it's an FAQ, but since is no FAQ and I didn't
find a solution in the list archives, here we go:
I want to use RRDTOOL to log certain attributes about
my proxy-server. Connect Time, Request Time, Transfer Speed.
So I set up a rrd:
--
rrdtool create proxy.rrd DS:t_connect:GAUGE:900:0:U
RRA:AVERAGE:0.5:1:288 \
DS:t_request:GAUGE:900:0:U RRA:AVERAGE:0.5:1:288 \
DS:speed:GAUGE:900:0:U RRA:AVERAGE:0.5:1:28
--
My Data is being collected by a Perl-Script (every 5 minutes by cron)
and reliably
delivers the correct output-data, which is then feed to rrd by
RRDs::update.
--
RRDs::update ($rrd, "--template", "t_connect:t_request:speed",
"N:$t_con:$t_req:$speed");
--
So far, so good. But trying to retrieve the collected data from the rrd,
I only get NaN's. No matter what value I'm trying to store into the
rrd,
it won't accept them.
But when I run my Script about every 5 seconds, data gets stored into
the rrd.
How can get rrd (or my script) to reliably store the 5-minute averages
into my rrd?
Thanks advance,
Oliver Kuegow
