[rrd-users] rrd for application monitoring

[Tobias Oetiker]

Hi Liehann,

if you don't mind the individual updates not going into the
database, then you can easily use rrdtool. you just may have to add
a pre-processing step that gobbles up the data from the webserver
for an rrd-step and then feeds it to rrdtool

cheers
