Customizing the loading of data collectors
When Strobe measures a target program, it determines whether it should invoke any of the available data collectors. Strobe searches LINKLIST for a module that has a prefix of STRB and a suffix that contains the first four characters of the target program name. The Strobe data collectors use the IBM- or vendor-supplied name for the subsystems that they support.
Subsystem Data Collector Name and Alias
Subsystem | Data Collector Name | Alias |
|---|---|---|
Adabas | STRBNATL | STRBADAB, STRBADAR, STRBNATB |
CICS | STRBDFHS | |
Db2 | STRBDSNY | |
Advantage CA IDMS | STRBIDMS | |
CA Gen | STRBDIEF | |
IMS | STRBDFSR | STRBDFSM |
WebSphere MQ | STRBDCSQ | |
Natural | STRBNATL | STRBADAB, STRBADAR, STRBNATB |
If you use the Strobe Db2 data collector, Strobe invokes it for all measurement sessions. If the Db2 data collector determines that the target region does not support Db2, the data collector disables itself.
If you use nonstandard names to initialize any of these subsystems, link edit the data collector again, supplying the alias you are using. You cannot rename the data collector.
The Strobe Interface supports user-written data collector programs that supplement performance data collected by Strobe and its options. Part 6, Strobe Interface in the Using-Strobe-options describes the interface and explains how to code a data collector program.
