No definitely not. Most of the data is disk/buffer activity. If left they will wrap at 2GB, but they can be reset manually back to zero. By history data, I mean the rrdtool graphs don't show the old spikey line. I.e Nice spiky line, reset the data at 12:00, spikey from before 12:00 is no longer displayed and a new line starting at 12:00 is displayed. Hope that makes sense. I'm trying to leave things running for longer to make sure that I'm not causing the problem by unrealistically resetting the data too often > > > Am I using the correct DS? > > >From what I read here, it is.

This is why setting min > and max (during rrdtool create) is a good idea. -- Paul Watson # Oninit Ltd # Growing old is mandatory Tel: +44 1436 672201 # Growing up is optional Fax: +44 1436 678693 # Mob: +44 7818 003457 # www.oninit.com # -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
