SMF Type 119 Record - Subtype 7

This table shows the record layout for type 119 SMF records
(TCP/IP Statistics - Server Port Statistics 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 7 Port Statistics record, as an interval record, periodically records statistics on ports that have been configured with the PORT statement in the TCP/IP PROFILE. This excludes all ports defined by PORTRANGE, or for which the RESERVED flag has been set. Each TCP or UDP port's activity is reported; connection information is provided for TCP ports, and traffic information is provided for UDP ports. Depending on the number of reserved ports, this report might actually be spread across multiple records.

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

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.

Spectrum SMF Writer - the 4GL SMF Report Writer.

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!
