PTrace Commands
4. Display the trace file with PTrace.
For additional information on using PTrace, see the PTrace Reference Manual.
Device Type and Subtype
When a trace file is created, the type and subtype of the device being traced are
recorded in that file. When PTrace opens the trace file, it uses this information to
determine for which subsystem PTrace is formatting records.
The device type and subtype for the TCP6MAN are 72 and 0, respectively. The device
type and subtype for TCP6SAM are 48 and 0 respectively.
PTrace Commands
PTrace commands provide options for selecting trace records for display, so you can
suppress those records that do not relate to the problem you are investigating. The
PTrace commands also provide options for specifying the way in which the trace
records are formatted.
Although PTrace provides a common set of commands for displaying trace records, not
all the PTrace commands are supported by each subsystem. This is because of the
structure of the PTrace code. The PTrace code actually consists of two modules. The
first module contains the code shared by all subsystems; the second contains the
additional, subsystem-specific code that actually displays the PTrace records.
Therefore, those commands implemented by the first PTrace module are supported by
all subsystems: ALLOW, COUNT, ENV, EXIT, FC, FIND, FROM, HELP, LIMIT, LOG,
NEXT, OBEY, OUT, PAGESIZE, RECORD, and RESET. Those additional commands
implemented by the subsystem-specific PTrace modules vary from subsystem to
subsystem. Of the commands that fall into the subsystem-dependent category, the
NonStop TCP/IPv6 subsystem supports:
•
DETAIL
•
HEX
•
LABEL
•
OCTAL
•
SELECT
•
TEXT
The HEX, OCTAL, and TEXT commands are implemented in the standard manner.
The LABEL and SELECT commands vary slightly from the standard, as described later
in this section.
These subsystem-dependent commands are not supported:
•
EBCDIC
•
FILTER
