For a start, you can replace the snmp data acquisition with any program or script that you want, which means that you can monitor absolutely anything at all - I've monitored exchange rates, wind direction and strength, you name it. It also has the ability to run scripts when thresholds are crossed - that is *REALLY USEFUL* when setting up a site the way I like it - ie it tells you if something has changed, and you then go and check up. On one site, I was monitoring the number of incoming emails, and a major increase heralded the arrival of another virus propagating itself... that allowed us to disconnect from the net within seconds, research, and put a fix in place well before any major damage has beem done. If you use the alternate RRD backend, then you can also display more thn one pair of data per graph. I recommend anyone who is looking after machines, comms equipment, or anything similar to spend the time necessary to get your hear around this tool. Only problem is that it's all in perl (: Even so, Tobi has made a huge contribution to the quality of life of SysAdmins. Steve
