Specifying the Location for Message Logging
PXMCOM messages and PATHCOM messages are logged to the OUT file you specify
when you start PXMCOM with a TACL RUN command. If you do not specify the
OUT parameter in the RUN command, these messages are sent to the current TACL
output file; this is typically the home terminal for the TACL process.
All the PB processes, LCS processes, PATHMON processes, and TCPs in a
Pathway/XM environment send their error and status messages to one or two log files.
The LINKMON processes also send link-management messages to these log files. You
can use the PXMCOM LOG1 and LOG2 commands to specify what kinds of messages
are logged by these processes, where they are logged, and how they are formatted in the
log, as described in the next subsection, Specifying the Location for Message Logging
.
LINKMON log messages are messages written to the Event Management Service
(EMS) central event log file, $0, during initialization of the LINKMON processes. They
are of the following form:
LINKMON ( LINKMON-process-name | CPU,PIN ) - message-text
where LINKMON-process-name is the name of the LINKMON process , CPU,PIN is
the processor number and process identification number (PIN) of the LINKMON
process, and message-text is a brief description of the error that can contain
variables.
These are unnumbered type 512 EMS event messages that you can display from the
EMS log with an EMS printing distributor or the ViewPoint application. See the EMS
Manual or the ViewPoint Manual for more information. Although type 512 messages
are sent to the EMS collector $0, they are not included in the Operator Messages
Manual; that manual contains only numbered messages.
Message text, cause, effect, and recovery information for messages from PXMCOM,
PB, and LCS processes are given in Section 13, PXMCOM, PB, and LCS Messages
.
Message text, cause, effect, and recovery information for the other types of messages are
given in the system management manuals for your version of NonStop
TM
TS/MP and
Pathway/iTS.
Specifying the Location for Message Logging
Run-time messages from PXMCOM, PB, LCS, PATHMON, TCP, and LINKMON
processes in a Pathway/XM environment are logged as directed by the LOG1 and LOG2
commands in PXMCOM. All of these processes log to the same one or two log files.
The following paragraphs provide a general description of message logging and the
LOG1 and LOG2 command options. For the complete syntax of the LOG1 and LOG2
commands, refer to LOG1 and LOG2
on page 11-41.
You can use the LOG1 and LOG2 commands to request reporting of errors only, or
reporting of errors and changes in object status as well. You can request that
information be logged to only one file, or that it be copied to two files. Also, you can
request that error and status information be formatted either as text or as Event
Management Service (EMS) tokenized event messages.
You can log information to a command terminal, a disk file or both; it is recommended,
however, that you do not specify a terminal only. On a terminal, log messages are lost
