bos getlog

Purpose

Prints a server process's log file

Synopsis

bos getlog -server <machine name>  -file <log file to examine>
           [-cell <cell name>]  [-noauth]  [-localauth]  [-help]
   
bos getl -s <machine name>  -f <log file to examine>  [-c <cell name>]     
         [-n]  [-l]  [-h]

Description

The bos getlog command displays on the standard output stream the specified log file from the machine named by the -server argument. The BOS Server fetches the log file from the /usr/afs/logs directory unless an alternate pathname is provided as part of the -file argument.

Cautions

Log files can grow quite large, especially for the database server processes. To keep them to a manageable size, periodically either use the UNIX rm command to truncate each log file, or use the bos restart command to restart each process.

It can take up to five minutes after the file is removed or process restarted for the space occupied by a log file to become available.

Options

-server

Indicates the server machine from which to retrieve the log file. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see the introductory reference page for the bos command suite.

-file

Names the log file to display. If a filename only is provided, the BOS Server fetches the log file from the /usr/afs/logs directory; the standard values are:

AuthLog: The Authentication Server (kaserver) log file
BackupLog: The Backup Server (buserver) log file
BosLog: The BOS Server (bosserver) log file
FileLog: The File Server (fileserver) log file
SalvageLog: The Salvager (salvager) log file
VLLog: The Volume Location (VL) Server (vlserver) log file
VolserLog: The Volume Server (volserver) log file

If a pathname and filename are provided, the log file is retrieved from the indicated directory. Partial pathnames are interpreted relative to the /usr/afs/logs directory.

-cell

Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see the introductory bos reference page.

-noauth

Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see the introductory bos reference page.

-localauth

Constructs a server ticket using a key from the local /usr/afs/etc/KeyFile file. The bos command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see the introductory bos reference page.

-help

Prints the online help for this command. All other valid options are ignored.

Output

The output is preceded by the line

   Fetching log file 'filename'...

The remainder of the output depends on the particular log file.

Examples

The following example displays the FileLog file from the machine fs3.abc.com:

   % bos getlog -server fs3.abc.com -file FileLog
   Fetching log file 'FileLog'...
   Sun Nov 8 04:00:34 1998 File server starting
   Sun Nov 8 04:00:39 1998 Partition /vicepa:  attached 21 volumes; 
                           0 volumes not attached
   Sun Nov 8 04:00:40 1998 File Server started Sun Nov 8 04:00:40 
                           1998
   Mon Nov 9 21:45:06 1998 CB: RCallBack (zero fid probe in host.c) 
                           failed for host 28cf37c0.22811

Privilege Required

The issuer must be listed in the /usr/afs/etc/UserList file on the machine named by the -server argument, or must be logged onto a server machine as the local superuser root if the -localauth flag is included.
