Technical data
START
/PROTOCOL=(protocol-identifier,...)
/NOPROTOCOL
Specifies the type of analysis performed on each trace record. The protocol data in
each trace record is analyzed for each of the protocols listed in the /PROTOCOL
qualifier, in the order in which they are specified. If you do not specify this
qualifier, only the protocol data supplied at the protocol level of the originating
tracepoint is analyzed; protocol data from lower levels is displayed, unanalyzed,
as user data. If you specify /NOPROTOCOL, no analysis is performed on the
protocol data in the trace record; it is all presented as user data.
/REVERSE
/NOREVERSE
Specifies that received data will be displayed in reverse video, and titles will be
displayed in bold. The default is /REVERSE.
/SAVE_BUFFER_SIZE=n
Specifies how many screens of saved lines of data will be kept. These lines can be
examined by using the NEXT and BACK commands. The default is 30 screens.
The minimum is 1 screen. The maximum is 1000 screens.
/SELECT=(protocol-identifier,...)
Specifies which protocol analyses are to be displayed. This qualifier is only useful
if you have used the /PROTOCOL qualifier to request multiple protocol analysis
of a trace record. The default is to display all the protocol analyses requested by
the /PROTOCOL qualifier.
/TRUNCATE
/NOTRUNCATE
Specifies whether data that will not fit on one line is truncated or continued on
the next line. The default is /NOTRUNCATE.
/WIDTH=n
Specifies the width of the output. The default is the width of your terminal
screen.
Detached or Live Tracing
/BUFFER_SIZE=n
Specifies the size, in bytes, of each CTF internal trace buffer (used for remote
tracing only). The default buffer size is 512 bytes. The minimum buffer size is 68
bytes. You can set this value larger to enable CTF to include more trace records
in a single buffer.
/CAPTURE_SIZE=n
Specifies the amount of data, in bytes, captured in each trace record. The default
data size is 188 bytes. The minimum data size is 0. The maximum data size is
5000 bytes.
/COLLECT
/NOCOLLECT
NOCOLLECT prevents collected trace records being written to a trace file or
displayed on your terminal until you issue a COLLECT command. The buffer
into which trace records are collected is used as a circular buffer; when the
buffer is full, new trace records overwrite the oldest trace records. The default is
/COLLECT.
