Use the TCP Listener attributes to display performance and identifying information for a specific listener connection.
Accepted Connections The number of connections accepted by this listener during the most recent time interval. A valid value is an integer.
Active Connections The number of current connections. A valid value is an integer.
Active Connections High Water Mark The high-water mark, which is the highest value recorded in the active connections field, for this listener. A valid value is an integer.
APPLDATA The result of an SIOCSAPPLDATA ioctl query. Use the APPLDATA attribute to enable applications to associate 40 bytes of application-specific information with TCP sockets that they own. This information can assist problem determination, capacity planning, and accounting applications. A valid value is a string of up to 40 characters.
