PtLog - Traces Protection Server operations
The PtLog file records a trace of Protection (PT) Server (ptserver process) operations on the local machine and describes any error conditions it encounters.
If the PtLog file does not already exist in the /var/log/yfs directory when the PT Server starts, the server process creates it and writes initial start-up messages to it.
The file is in ASCII format.
Administrators listed in the /usr/afs/etc/UserListExt file can use the bos getlog command to display its contents.
log onto the server machine and use a text editor or a file display command such as the UNIX cat command.
the mode bits on the VLLog file grant the required
r (read) permission to all users.
The PT Server records operations only as it completes them, and cannot recover from failures by reviewing the file. The log contents are useful for administrative evaluation of process failures and other problems.
The server can record messages at three levels of detail.
it records only very rudimentary messages.
To increase logging to the first level of detail,
issue the following command while logged onto the server machine as the local superuser
# kill -TSTP <server-pid>
where <server_pid> is the process ID of the vlserver process, as reported in the output from the standard UNIX ps command. To increase to the second and third levels of detail, repeat the command.
To disable logging, issue the following command:
# kill -WINCH <server-pid>
To decrease the level of logging, first completely disable it and then issue the
kill -TSTP command as many times as necessary to reach the desired level.
To rotate the log file, rename the existing file and then issue the command:
# kill -HUP <server-pid>
This will instruct the server to close and reopen the log file.
