[Omaha.pm] rrdtool rulez, I second that thought

[Mat Caughron]

Jay et al:

Yes, rrdtool rrulez.  There's a sweet little php front-end to it too:

I installed this in like 2002 and it still works like a charm.
Amazing how compact the time data storage and that they built it to not
have to change in 3+ years.

Looks like now they've got scripts for monitoring pretty much every solid
daemon; bind, sendmail, qmail, pluls snmp traps, mysql table rows,
iptables bandwidth usage, yada yada

Full of delicious and chewy *nix goodness and so, so right for the price.
