Filtering events
QNX SDP8.0System Analysis Toolkit (SAT) User's GuideUser
The tracelogger utility gives you some basic control over filtering
by way of its -F option.
This filtering is limited to excluding entire classes of events at a time;
if you need a finer granularity, you can use
TraceEvent(), as described in the
Filtering
chapter in this guide.
By default, tracelogger captures all events from all classes,
but you can disable the tracing of events from particular classes as follows:
| To disable this class: | Specify: |
|---|---|
| Kernel calls | -F1 |
| Interrupt | -F2 |
| Process | -F3 |
| Thread | -F4 |
| Communication | -F6 |
| System | -F7 |
You can specify more than one filter by using multiple -F options.
Note that you can't disable the Control or User classes with this option.
For more information about classes, see the
Events and the Kernel
chapter of this guide.
