cufwPolConnNumHalfOpen
Module: CISCO-UNIFIED-FIREWALL-MIB
OID (symbolic): CISCO-UNIFIED-FIREWALL-MIB::cufwPolConnNumHalfOpen
OID (numeric): 1.3.6.1.4.1.9.9.491.1.1.4.3.1.9
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The number of connections that are currently in the process of being established, corresponding to the protocol denoted by 'cufwPolConnProtocol', in the policy 'cufwPolConnPolicy' applied to the entity identified by 'cufwPolConnPolicyTarget'.
What is cufwPolConnNumHalfOpen?
This Gauge32 reports how many connections are currently mid-establishment for the protocol/policy/target combination identified by cufwPolConnProtocol, cufwPolConnPolicy, and cufwPolConnPolicyTarget. It gives an admin a live view of in-progress connection setup specifically under one policy applied to one target, useful for isolating congestion to a particular rule rather than the firewall as a whole. A persistently elevated value for a policy governing a particular server target could indicate that target is slow to complete handshakes under that policy's current constraints.
