Hey Loose - thanks for the reply. I agree any up to snuff IT group had better have an accurate inventory of their assets. We absolutely do have that.
My problem, or I guess more accurately management's problem, is that the OpenNMS system did auto-discovery. It uses SNMP traps to discover when a new host has been added and sends alerts and creates a host entry. They see it as a fundamental feature.
I have been selling Nagios as a significant upgrade, but they keep coming back with "but it doesn't do auto -discovery". Thankfully they are sold on Nagios despite this, and we will enjoy many of the system's advantages over OpenNMS, but this is one feature that I would have expected to be there and IMO sorely miss. Not to look a gift horse in the mouth, this is a fantastic piece of software at any price, particularly free, and I am very appreciative to all who worked on it and continue to support it. I just would have expected such a widely implemented app to have solved what has to be a problem every installation has encountered.
Just imagine if it did discover and create host entires for every machine plugged into your network, how valuable would that be? I am not a coder or I would seriously consider attacking this issue. I have been looking for an excuse to learn Perl, maybe this is it:?:
Thanks for your feedback regardless!
