The Order of the Blue Polo - Member 000031
My name is Paul Cole. I am a contractor working currently for Environment Canada (under Shared services Canada).
It was a beautiful thing to be given the OpenNMS project in order to map out and bring together teams to monitor and work on the very large LAN. A multitude of tools and scripts were used custom to each area, and we are now moving towards unification.
The visibility and baseline abilities of OpenNMS are fantastic, and the new topo-mapping/ geo-mapping features are looking fantastic come version 1.14 !
Our network size is larger than the current scope of nodes we are testing with , but OpenNMS is managing pretty smoothly and seamlessly.
I have released some of the scripts I wrote to contribute back to the community that are based on version 1.10-1.12 and hope they help more people realise the power and scalability of the product.
Currently our OpenNMS build is monitoring over 15k nodes and 20k interfaces and 25k or more services (exact numbers can be extracted but it grows every quarter), on an 8 core server with 16GB RAM using the discovery method.
It is keyed to discover every IP and node it can and monitor switches/UPS’s and routers and select key devices for management, to send email alerts to the appropriate regional teams when a device is down or a specific threshold or alert is received.
I can’t of course send out network diagrams , but I can send a screenshot of the Geo-map to give an idea of how it goes.
