Syslogd info !!!

HP-UX_Ali — Sat, 14 Aug 2010 15:17:16 GMT

Dear All experts ,

Required your Input regarding Syslogd in debug mode.

our DBA team requested the system log files in debug mode, as the requirement from oracle after raising SR with oracle. they want to run the syslogd for 1 day and also a s/w called OS watcher.

Pls confirm the below procedure is correct.

1. kill the existing syslogd process
2. start the syslogd process in debug mode
"/usr/sbin/syslogd -d & to run in back ground.
3. after a day kill the process for syslogd -d
4.star the syslogd in normal mode.
/sbin/init.d/syslogd start

zip the syslog.log file and mail to our account.

If any other input will be apprecitaed...

Thanks
ALi

Use -Dd since you don't want the kernel messages sent to the console. Also, & is not necessary. syslogd is a proper daemon and will place itself in the background automatically.

> 3. after a day kill the process for syslogd -d

You can use the same technique:

kill $(cat /var/run/syslog.pid)

syslogd automatically puts its PID in the above file when it starts.

> 4.star the syslogd in normal mode.
/sbin/init.d/syslogd start

Correct.

If you need to see the syslogd priority and facility values, add -v to the command line (syslogd -Ddv) and to permanently enable these two numbers in syslog files, add the option to the startup config script in /edtc/rc.config.d/syslogd.

No, the current syslog.log file will be moved (not appended) to OLDsyslog.log and a new syslog.log is started. To prevent this, just start syslogd from the command line.
