3.8 Filtering
Filtering reduces the impact of tracing on system performance by reducing the
number of trace records collected. This, in turn, reduces, the number of trace
records that have to be written to trace files or displayed on a terminal.
Each trace record includes an event code that indicates the type of event that
caused the trace record to be generated. You can use the /FILTER qualifier in
the START command to specify that only trace records with specified event codes
should be collected. For example, most tracepoints generate trace records for
the Receive and Transmit events; you can use /FILTER to specify that only trace
records generated for Transmit events are to be collected.
For example:
CTF> START/FILTER=TX "ROUTING CIRCUIT UNA-0"
starts tracing at the specified tracepoint, but indicates that only trace records
with event code TX (transmit) are to be collected.
