I don’t even know what PRTG stands for, but yes, all the info that cnMaestro graphs is available in SNMP.
Yes, iReasoning works for verification. And we provide the MIBs for download every release. Are you aware there are 3 MIBs? AP, SM and Box (that applies to AP and SM).
Sorry so many questions… but I recommend loading all those MIBs and walking them and you’ll find lots and lots of information. Enjoy!
