A good SNMP implementation with a set of supporting MIBS makes network management and alerting a breeze.
You must be trolling! That is less likely than finding a good implementation of communism!
The "adjective rule" - which is that whenever there is an adjective used in the name of something, it means the exact opposite - applies very strongly to SNMP:
"Simple" - Not at all, SNMP is and ancient Complex and Twitchy beast,
"Network" - Nope, SNMP "manages" some parts of some Devices that happens to be on a network,
"Management" - Nah, we can maybe, because UDP, Get/Set some bits in whatever order we or the network like, no Rules, no ACID and no Rollback. This is for Debugging, not Management.
"Protocol" - Yes, there is a Protocol (it sucks, but, it is there).
SNMPv1 is a steaming pile of dinosaur crap, SNMPv2 kinda works, but, anyone using SNMPv2 for more than Graphing is a Retard, and SNMPv3 ... oh, boy ... anyone using that special combination of stupidity, sadism and forced restraint is a Gimp!
Telecoms, who need 'management' that can manage things without blowing up, they use NETCONF with Conf-d or similar: https://www.tail-f.com/confd-basic/
I.O.W.: I don't like SNMP very much.
