cpqOsTcpConnectionFailures
Module: CPQOS-MIB
OID (symbolic): CPQOS-MIB::cpqOsTcpConnectionFailures
OID (numeric): 1.3.6.1.4.1.232.19.2.11.2.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Connection Failures is the number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
What is cpqOsTcpConnectionFailures?
This read-only integer counts TCP connections that transitioned directly to CLOSED from SYN-SENT or SYN-RCVD, or from SYN-RCVD to LISTEN, representing failed connection setup attempts. An admin watches this for signs that clients or peers are failing to establish TCP sessions with this server. For example, a rising cpqOsTcpConnectionFailures count could indicate a firewall blocking connections mid-handshake or a service refusing connections.
