I want to work with opennms for making a very basic monitoring devices through ICMP Polling and traps reception only. We will have a lot of devices (between 300.000 and 3 millions). As I said, we want only a monitoring based on ICMP polling (for example every 15min) and basic trap reception (critical error).
Do you know how we can achieve this monitoring with opennms. I mean, hardware requirment? can we include a distributed architecture or do we have to install several independent servers with opennms?
