SMF Type 120 Record - Subtype 11

This table shows the record layout for type 120 SMF records
(WebSphere Appl - Liberty Server).

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

Purpose: WebSphere Application Server writes record type 120 to collect WebSphere Application Server performance statistics.

Record type 120 has the following subtypes:

Subtype 1 - the Server Activity record
Subtype 6 - the Server Interval record
Subtype 5 - the J2EE Container Activity Record
Subtype 6 - the J2EE Container Interval Record
Subtype 7 - the WebContainer Activity record
Subtype 8 - the WebContainer Interval record
Subtype 9 - Network Deployment (z/OS) Request Activity record
Subtype 11 - Liberty server log information about HTTP requests

Subtype 11 - Liberty server log information about HTTP requests

It's easy to report on SMF 120 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 120
WebSphere Application Java CPU Times

The sample SMF report below was created with Spectrum SMF Writer, the low-cost 4GL SMF report writer. It reads as input the SMF file and selects just the type 120 WebSphere Application records for Jave 2 Enterprise Edition containers. (See SMF 120-5 record layout.) It then prints a report line for each Java bean method accounting section found. The report shows CPU time information about those Java bean methods. Note that a single SMF 120 record can contain information about multiple beans and multiple methods per bean.

All of this with just a few of code!
