Stopping the Adapter
Use the init.tecad_logfile stop command to manually stop the adapter. Always use
this command to ensure that the syslogd daemon is correctly configured to stop
sending messages to the adapter. If the adapter is stopped with any other method,
the syslogd daemon might exit because the adapter is no longer listening on the
named pipe the syslogd daemon is writing to.
Note: The endpoint adapter can be automatically stopped by distributing an ACP
that has the adapter start command removed from the after-file-distribution
actions. See the IBM Tivoli Enterprise Console User’s Guide for additional
information.
Running Multiple UNIX Log File Adapters
You can run multiple instances of the UNIX log file adapter on a single system. It
is recommended that additional adapters be run as non-TME adapters. To monitor
different log files, each instance of the adapter must have its own configuration,
format, class definition statement (CDS), and error files.
If you want to stop an adapter when multiple log files are running, you must
specify the name of the adapter to stop. If you do not specify the adapter to stop,
the default adapter without a name is stopped.
The syntax for the init.tecad_logfile command is the following:
init.tecad_logfile [–s]{start | stop}[AdapterID] &
If the –s flag (skip syslog) is specified, the adapter does not monitor the syslogd
daemon.
If the –s flag is not specified, use & so that the command runs in the background
while returning a command prompt to your session. Otherwise, because an
adapter started without the –s option forks a child process to run the adapter, the
process does not return to the command line until the child process ends.
Note: If you start the adapter with the –s flag, you can also use the –s flag when
you stop the adapter to avoid reconfiguring the syslogd daemon. You can
also stop the adapter without the –s flag and it still works. However, do not
stop an adapter with the –s flag if you did not start it with the –s flag.
If the –s flag is not specified, the UNIX log file adapter startup script uses a UNIX
pipe to monitor the syslogd daemon and the syslogd daemon is configured to
write to the pipe, and the UNIX log file adapter reads from that pipe. When the
adapter ends, the startup script will reconfigure the syslogd daemon to stop
writing to the pipe before stopping the UNIX log file adapter.
Do not configure more than one UNIX log file adapter to read from the syslogd
daemon on a particular system.
The following command starts a UNIX log file adapter called syslog that monitors
all syslog messages:
init.tecad_logfile start syslog &
