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. The format is an integer.
Active Connections The number of current connections. The format is an integer.
Active Connection High Water Mark The high-water mark, which is the highest value recorded in the active connections field, for this listener. The format is an integer.
Application Name The job name associated with the application address space that opened and bound the socket. The format is a string up to 8 characters in length.
ASID The z/OS address space ID of the address space that opened the socket. This value is displayed as an four-digit hexadecimal value.
Backlog Connections Rejected The number of connections rejected during the most recent time interval because the backlog limit was exceeded before the listener was able to accept the waiting connections. z/OS Communications Server rejects a new connection when the number of connections waiting to be accepted exceeds the backlog limit for a listener. The format is an integer.
Backlog Connections Rejected Time Stamp The date and time that a connection was most recently rejected because the backlog limit was exceeded. The format of date and time is determined by the date and time formats specified in User Preferences. The time stamp reflects the time zone specified in User Preferences.
This value is stored as a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:
When no connections have been rejected, this value is stored as a character string of zeros and displayed as blank.
Backlog Limit The maximum number of connections allowed in backlog at one time. The format is an integer.
Collection Time The time and date of the data sampling. This time is displayed in the following format:
mm/dd/yy hh:mm:ss
Where:
The stored format is a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:
Connection Rate The average number of accepted connections, per minute, during the most recent time interval. The format is an integer.
Connections in Backlog The current number of connections in backlog. The format is an integer.
Hex Connection Number The hexadecimal representation of the connection number. The format is an 8-digit hexadecimal string.
Idle Time Since Last Accept The amount of time, in hours, that the server has been idle since the most recent connection was accepted. This value is displayed as a real number.
Local IP Address The local IP address for this connection. This IP address is 0 (zero) when the application accepts connections to any local IP address. The format is a string up to 45 characters in length.
Local Port The local port for this connection. The format is an integer.
Origin Node The unique identifier for the TCP/IP stack being displayed. The format is a string up to 32 characters in length.
Percent Active Connections The number of active connections in this collection interval as a percentage of the active connections high-water mark. The format is an integer.
Server Up Time The amount of time, in hours, that the listener has been active. The format is a real number.
Sysplex Name The name of the sysplex that the monitored system is part of. The format is a string of up to 8 characters.
System ID The SMF system ID. The format is a string up to 4 characters in length.
TCPIP STC Name The TCP/IP job name. The format is a string up to 8 characters in length.
Time Stamp for Active Connections High Water Mark The date and time when the highest value was recorded for the active connections. This time is displayed on the interface in the following format:
mm/dd/yy hh:mm:ss
Where:
The stored format is a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:
