Network monitoring Ideas wanted

Network monitoring
Goals: actively monitor and track inventory
Detect unauthorized hardware and software
Monitor critical systems for; temp, HD space, Ram, CPU usage, Services...

1. Passively discover devices
2. Actively discover devices
3. Track devices based on MAC and device name
4. Quickly find IP address currently associated with the device
5. Use SNMP or Agent for critical devices
6. Inventory all hardware and software assets
7. Alert on changes made to devices or software installed
8. Email and SMS Alerts

We currently are using servers alive which does a ping sweep and can use snmp or an agent. It does not perform discovery.

Haven't found something that does everything I would like and am hoping for some suggestions.

I'm thinking about using OCS-inventory and GLPI for asset and inventory

Autoscan v0.99 on the backtrack cd does a great job of finding everything but the newer versions choke when they see our OCE printers and it won't send an alert.

I have Zenoss running on CentOS and it runs well but doesn't do a passive discovery and it seems to only discover SNMP enabled devices. Map is pretty though and Management likes pretty.

I'll be trying out Zabbix and Groundwork soon.

netdiscover did a great job of finding everything but I haven't found a way to save the results. Anyone know how? I tried sending it to a txt file but I just end up with the first few results listed over and over again.

Well in terms of slightly fluffier advice, i'd suggest not necessarily writing off any one product becuase of a lack of a documented feature if you're able to manually replace it yourself. Discovery is a good one. if it doesn't do discovery then you can, as you've found, use another tool to do that discovery. most MNS products have some SQL back end, so maybe you can insert the data yourself and let it run from there? I long ago admitted defeat in finding the perfect product and use a number of different ones and manually pull and push data between them to get everythign covered as i want it to.

Getting sharper

Well this would be a great chance to learn more and I would love nothing more than to tinker and figure it out but between school and work I don't think it's likely to happen soon. Most of the OSS stuff I've been looking at is much better than what we currently use but my goal is to actually have my boss sign off on it. Zenoss, Zabbix, Groundwork, Nagios, OpenNMS are the 5 that I am looking at and will attempt to winnow it down to two before I send the to the boss. Then I'll work on the other stuff.
