The current system sessions number: 1.3.6.1.4.1.2011.6.122.15.1.2.1.4
Current TCP session: 1.3.6.1.4.1.2011.6.122.15.1.2.1.6
Current the UDP number of sessions: 1.3.6.1.4.1.2011.6.122.15.1.2.1.7
Current ICMP number of sessions: 1.3.6.1.4.1.2011.6.122.15.1.2.1.8
This does not distinguish between the product model, USG firewall OID is the same, of course, possible that some models may not implement OID on the OID.
