syslogs on AIX machine

I need to view syslog on AIX machine. I have no clue about this. I went through syslog.conf file and got something like this:

# "mail messages, at debug or higher, go to Log file. File must exist."
# "all facilities, at debug and higher, go to console"
# "all facilities, at crit or higher, go to all users"
#  mail.debug           /usr/spool/mqueue/syslog
#  *.debug              /dev/console
#  *.crit                       *
#  *.debug              /tmp/syslog.out     rotate size 100k files 4
#  *.crit               /tmp/syslog.ou开发者_高级运维t     rotate time 1d

Also,I donot know how to access /dev/console Can somebody help out?

See How to configure AIX syslogd and managing AIX logs.

From your configuration, I see that all syslogged information can be found in /tmp/syslog.out since this is where *.debug is being logged.

If you don't find anything there, you should check if the syslogd daemon is actually running.

If you make a change to syslog.conf file, you have to restart the daemon using

refresh -s syslogd

Update: I see that everything in syslog.conf is commented out. If you want to see some logs, you have to enable some logging facility. For example, it should look like this:

# "mail messages, at debug or higher, go to Log file. File must exist."
# "all facilities, at debug and higher, go to console"
# "all facilities, at crit or higher, go to all users"
#  mail.debug           /usr/spool/mqueue/syslog
#  *.debug              /dev/console
#  *.crit                       *
*.debug              /tmp/syslog.out     rotate size 100k files 4
#  *.crit               /tmp/syslog.out     rotate time 1d

if you want to see anything in /tmp/syslog.out.

And, don't forget to restart the daemon!

Update 2:

To enable logging of everything, put this in syslog.conf:

*.*              /tmp/syslog.out     rotate size 100k files 4

This way you'll see if logging really is working.

You forget that the file must exist:

touch /tmp/syslog.out

refresh -s syslogd

Well, /dev/console is the console, a (almost certainly) physical terminal connected to the box itself. It's not a storage device that you can get the information back from.

As to which file you need to look at, it's usually controlled by that file you showed us and individual messages can be sent to different places based on the facility and priority. However, since all those lines you see are commented out, they'll go to the default, which is probably the console.
