What is tcpEStatsListenerExceedBacklog?
Count of connections dropped from this listener's backlog for any reason, including ones allocated resources but never accepted; a rising counter is a strong sign the application isn't accepting connections fast enough or the backlog is undersized.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.6 snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerExceedBacklog
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.6.1 snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerExceedBacklog.1
