Configuring Activity Tracing 
Use
TREX processes search requests, index creation requests, and so on using different services. Activity tracing must therefore be enabled for each individual service.
The following TREX configuration files need to be modified:
● TREXIndexServer.ini
● TREXPreprocessor.ini
● TREXQueueServer.ini
● TREXWebServer.ini
Procedure
...
...
...
1. Open the TREX configuration files and check for the relevant entries.
You can find the configuration files at <TREX_DIR>\<trex_hostname>.
The configuration files must contain the sections below so that TREX can write activity traces. If they do not yet exist, you have to create them:
[ccms]
record = on
satracer = Jarmlike
[satjarmlike]
file = <sat_file>
2. Create the following empty TREX trace files:
○ TrexIndexServer.sat
○ TrexQueueServer.sat
○ TREXPreprocessor.sat
○ TREXNameServer.sat
○ Webserver.sat
3. Replace <sat_file> in the TREX configuration files with the destination file for the trace information. The section <sat_file> specifies the path of the activity trace that the TREX server in question writes.
Use a path relative to <TREX_DIR>, such as:
○ trace/TrexIndexServer.sat
○ trace/TrexQueueServer.sat
○ trace/TREXPreprocessor.sat
○ trace/TREXNameServer.sat
○ trace/Webserver.sat
4. Install a log viewer server on every TREX host, and register the TREX trace files as described in the documentation for the log viewer.
Refer also to SAP Note 621466 about the log viewer.
5. Activate activity tracing for the user whose actions you want to trace by choosing System Administration ® Monitoring ® Portal ® Activity Tracing.
Result
You can analyze the activity trace if the user has carried out an action.
Firstly, you have to register the TREX activity traces with the log viewer server. For more information about registering log and trace files in the log viewer, see:
●
Registering a Log for
Viewing – Online Log Viewer
●
Registering a Log
– Stand-Alone Log Viewer
● SAP Note 621486. Log Viewer Note Overview
Once you have registered the TREX activity traces, you can display them in the log viewer.
In order for the TREX trace files (*.sat) to be displayed in the log viewer, you must display the SATTrace/PerfFormatter format in the log viewer. If you choose any other format, the trace file can not be displayed.
To view the trace files, do the following: LogViewer ® add a file ® navigate to trace folder and choose the trace file ® the trace file is displayed.
