syslogd options
 

Hi All,

Is anybody know that syslogd has the line number option ?
and Can I disable the repeated logs ?
I read manual and search on google but I cant found it.
Your help will be appreciate.

Thank you.

Hi,

Can you please explain what you mean with both statements?

Are you asking whether syslogd can insert a number in the
log-files?


What do you mean when you say "repeated logs"? Messages
like "this was repeated 20 times" to be expanded to have
all 28 entries instead? Do you want to stop log rotation?

Hello Tink,

Thank you very much for the reply.

1. I mean to say that "Is there any option to insert line number in syslog ?"

2. "Can I disable the repeated logs ?" means if same log came then I dont want to put that log in log file. Is this possible or is there any option for this ?

Will you please explain me what is "log rotation" ?

Sorry I am very new to syslog. I dont know the details about syslog.

Thank you.

Not that I'm aware off, and it doesn't really make too
much sense, either, as far as I'm concerned. What would
the use case be?

Excellent question; on slackware that's something
that "just happens", I never thought about configuring
it explicitly. What distro are you using?


Log rotation is not really a feature of syslog, but
rather of logrotate (which co-operates with syslog via cron).
What it does is to roll a log on an e.g. daily or weekly
basis for easy archival, or to prevent unlimited growth
of a file.

Hello Tink,
Thank you very much for the quick reply.
I am sorry that I couldn't explain you properly.

1. Line number option means suppose I want 100 lines only in the logfile. So log file should show only 100 lines. It should be overwrite the oldest line with 101th line.

2. I am using Fedora 5. I search some source code for syslogd I found 2 options one is busybox-1.6.0 (not used syslog.conf )and other is syslogd-1.4.1(uses syslog.conf). In busybox-1.6.0 version it shows all the log evenif it is repeated. In syslogd-1.4.1 version if log line get repeate it shows the message "last message repeated xx times".

3. How can I enable log rotate option ? Suppose I want log on hourly basis.


Thank you.

Regards

I'm fairly certain that you can't. And I fail to see
the benefit in a size-based rotation.


That's a question I hope someone with Fedora experience can answer.
I can't, since I don't use it. The distros I use (Slackware by
inclination; debian,suse and ubunut because they're here at work)
all come with logrotate, and the behaviour is configured via
/etc/logrotate.conf and files in /etc/logrotate.d

Fedora uses the same logrotate arrangement
