SMF Type 119 Record - Subtype 22

This table shows the record layout for type 119 SMF records
(TSO Telnet Client Connection Initiation Record).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: Transmission Control Protocol/Internet Protocol (TCP/IP) writes type 119 records to collect statistics about Telnet servers and clients, FTP servers and clients, and API activity and stack usage information.

The Subtype 22 TSO Telnet client connection Initiation record is collected at the establishment of a connection using the TSO Telnet client. This denotes the connection, rather than a particular session. This record contains pertinent information about the connection available at the time of its opening

It's easy to report on SMF 119 data! (Jump to sample reports)

SMF Spectrum Writer
We have a low-cost 4GL report writer especially for SMF files. It's called Spectrum SMF Writer.

Spectrum SMF Writer handles the difficult SMF record parsing for you automatically. You just specify which fields you want to see.

Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report.

Plus, Spectrum SMF Writer can export SMF data as comma delimited files to use on your PC.

Sample Report from SMF 119 Subtype 2 Records
Showing Information about TCP Connections


The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer.

In this report, we read as input the SMF file and select just the type 119 subtype 2 TCP Connection Termination records. (See SMF 119 Subtype 2 record layout.) The report shows information about terminated TCP connections, including start time, end time and computed elapsed time. It also shows the total number of bytes sent and received during the connection and the termination code. Our record layout also expands the 1-byte termination code into a readable descriptive text. The report is grouped by TCP/IP Stack and Resource. The report includes subtotals for each Resource.

All of this with just a few lines of code!
