Hi, (re-sent via correct email address) I'm currently looking into if it would be possible to use OpenNMS as a base for a network wide element monitoring system. I've been playing with it for a few days and the basic monitoring and SNMP stats gathering works fine. However to truly monitor a network of our elements will require a little deeper configuration. Our network consists of basestations which serve a number of clients. These clients do not appear directly on the management network although they all have SNMP functionality in them. The basestation provides a proxy service for each client on a spare port (which you discover by enumerating the basestations MIB) as well as listing the interface in it's standard ietf interfaces list. Looking around the documentation I think I could modify snmp-config.xml with appropriate port and proxy-host tweaking although it would be nice to see some example configs that did it. Would I be right thinking I would need a stanza like: <definition port=1234 proxy-host=123.123.123.123> <specific>111.111.111.111</specific> </definition> for each of the proxied connections I want to monitor? Which leads me to the next question about approach. We already have tools that enumerate the topology of our networks and understand the relationship between basesations and their clients. However OpenNMS does a good job of detecting basesations, including any new ones that appear on the network, but obviously not the clients as it doesn't know how to reach them. How easy would it be to teach OpenNMS how to discover the clients (and use the proxy)? Or would it be easier to generate a static configuration for OpenNMS from our tools and regenerate it if we see another basestation? Or is there a middle approach where OpenNMS detects a device of type X it can call an external program to generate further node configuration data for it's clients?
