hello,
3 things :
1/ AIX standard event logger (the errdaemon) can be viewed with :
errpt | more
detailed :
errpt -a | more
Clear log :
errclear 0
2/ Some circular files record what happens during installation, or system boot. You can consult them with the alog command :
List logs which can be seen with alog :
alog -L
Check a perticular log file :
alog -t <bootfile> -o | more
Example :
alog -t boot -o | more
Note : if you mistype your alog command, you will have the feeling that the shell hangs (in fact alog is waiting to record some information, just make CTRL-D to exit; the alog command can be used to record some events; a useful feature is that all the output to /dev/console is logged and can be viewed with alog).
Note that there are some shortcuts in smit to see theses circular log files.
3/ Syslog configuration
Quickly : edit /etc/syslog.conf, add a line at the end of file such as :
*.debug /my_logfile
Save, then create this /my_logfile BEFORE restarting syslogd :
touch /my_logfile
Then restart syslogd :
refresh -s syslogd
Monitor in permanence this file :
tail -f /my_logfile
To check this is ok, telnet your host and try to login with bad passwords, this should generate some error message.
NOTE : In order to have syslog intercept some events in an application, the coder of this application * must * have programmed it in order to be able to send messages to a syslog daemon
)
Last Note : many applications have their own log files, and don't care about syslog, errdameon, alog ... (Websphere ?).
regards,
