Full Discussion: Dmesg with date possible?
Operating Systems HP-UX Dmesg with date possible? Post 302893378 by ahamed101 on Wednesday 19th of March 2014 03:00:44 AM

a thought - why not clear the messages everyday after storing it into a log file with current date? a cron should do.

I just noticed the logs are already rotated. Not sure if your system does it. Check these files
Code:
root@maximus:/tmp# ls -lrt /var/log/dmes*
-rw-r----- 1 root adm     28 Jan  8 09:39 /var/log/dmesg.4.gz
-rw-r----- 1 root adm  13463 Feb 17 00:53 /var/log/dmesg.3.gz
-rw-r----- 1 root adm  13376 Feb 17 19:41 /var/log/dmesg.2.gz
-rw-r----- 1 root adm  13544 Feb 19 19:57 /var/log/dmesg.1.gz
-rw-r----- 1 root adm  49431 Feb 23 12:36 /var/log/dmesg.0
-rw-r----- 1 root adm  49773 Mar  2 16:27 /var/log/dmesg

On a second thought I guess these are created either when the system boots up or shuts down.

Script log_dmesg
Code:
#!/bin/bash
echo "<< Log for $(date) >>" >> /var/log/mydmesg.log
dmesg >> /var/log/mydmesg.log
dmesg -C

Cron entry
Code:
0 0 * * * /path/to/your/script/log_dmesg

and may be include some log rotation logic if needed.

strclean

strclean(8)						      System Manager's Manual						       strclean(8)

NAME

       strclean - Removes outdated STREAMS error log files

SYNOPSIS

       /usr/sbin/strclean [-d logdir] [-a age]

FLAGS

       Specifies  a  maximum  age  in  days for the STREAMS error log files if this not the default age of 3.  The value of age must be an integer
       greater than or less than 3.  Specifies a directory for the location of the STREAMS error log files to  be  removed  if	this  is  not  the
       default directory /var/adm/streams.

DESCRIPTION

       The  strclean  command cleans the STREAMS error logger directory of log files (error.mm-dd) that contain error messages sent by the STREAMS
       log driver (strlog).  If no other directory is specified (the logdir argument), the command removes error log files in the /var/adm/streams
       directory.  If no other age is specified (the age argument), the command removes error log files that have not been modified in 3 days.

       The strclean command is executed by the cron daemon on a periodic basis.

EXAMPLES

       To remove the day-old error log files from a directory called /tmp/streams, enter: strclean -d /tmp/streams -a 1

FILES

       One or more error log file or files on which strclean operates.	The mm.dd in the filename indicates the month and day of the messages con-
       tained in the file.

RELATED INFORMATION

       Commands: strerr(8), cron(8).

       Interfaces: strlog(7).  delim off
