Number of TCP Connections per State

Supported Agents Linux
This check monitors the number of TCP connections in the various possible states, which are: ESTABLISHED, SYN_SENT, SYN_RECV, LAST_ACK, CLOSE_WAIT, TIME_WAIT, CLOSED, CLOSING, FIN_WAIT1, FIN_WAIT2.


One service is created if there is at least one TCP connection. On agents supporting {tcp_conn_stats} this should always be the case since at least the connection to the agent should be shown.
