What I liked best compared to other cheaper tools is the processing of SNMP traps with the distributed agent on the monitored hosts themselves, so the traps didn't have to be sent across the network. And the interpretation of the traps with the Trap to policy function was also great. Review collected by and hosted on G2.com.
Expensive -> with the sale, the license prices rose extremely
