Hi:
I´d like know if Orion NPM record all events ocurred in the network, or if it´s
could lost any events.
It record all events in the network that being polled by it. Devices that are not being polled by NPM can see any event on that devices.
Or you can be more specific of what events you wanted to have. APM can gather event logs from servers, Syslog can gather logs from cisco devices, uptime/downtime, cpu load, memory utilization, etc
what type of event are you referring?
