As per my understanding , one SNMP session can hold at max 31767 (PDU_MAX_RID - PDU_MIN_RID). so if i want to monitor more devices say 500 with around 30 scalar oids for every 60 sec.
I see SNMP++ takes more time on getting the request id for snmp request(asynchronous).
if i want to monitor then around 2000 devices , i feel one SNMP session can not handle so many requests.
Kindly let me know your thoughts of working around this limitation.
