Tnx for the interesting info.
I tried cacti some years ago, but it wasn't quite what I expected.
But maybe I didn't give myself the time to explore it enough.
I want to monitor over the WAN.
PS Do I have to add a nat/firewall rule to enable this or is enabling snmp
Uptime, sysload, memory usage, bytes transfered, etc are the most important
creteria for me.
I will sure take a look at ez-cacti and opennms. The monitor host runs
debian etch. (now using smokeping, but I want more)
I also bumped into jffnms (http://www.jffnms.org) which also seemed to have
the things I want.
The sms alerts are very interesting. Is it really full included or did you
also write a script to use a service as voipcheap or something like it?
