hi all, I have a question, I am looking for open source software to monitor snmp, well from what I have seen most of them are expensive, I found one opennms which look ok, but do you know anyone that could built a graphic of the network similar to hp openview?
I've been in a similar situation and after looking around for a long time, I found nagios which is an excellent tool to monitor any IP device that supports snmp. You can set alarms, alerts and notifications via email, sms e.t.c and much more.
As I have been finding, MRTG is a pretty awesome tool for monitoring all my SNMP enabled devices. I had used the ported windows distro but it is very limited in scheduling. The Linux/Unix distro is rock solid and is easy to tweak.
