What is the best way to clean up log files on a syslog server.

We have a RHEL6 syslog servers to store all log files from many linux servers, those linux servers are running syslog client, and forward logs to this syslog server, the logfiles on this syslog server looks like this:

/var/log/syslog/server1/server1-date1.log
/var/log/syslog/server1/server1-date2.log
/var/log/syslog/server1/server1-date3.log
...

/var/log/syslog/server2/server2-date1.log
/var/log/syslog/server2/server2-date2.log
/var/log/syslog/server2/server2-date3.log
...

/var/log/syslog/server3/server3-date1.log
/var/log/syslog/server3/server3-date2.log
/var/log/syslog/server3/server3-date3.log
...

We want to clean up those log files regularly, for example to delete or move all "serverX-date1.log" and "serverX-date2log" to some where, and just keep all"serverX-date3.log" in that directory,

What is the best way doing this?

Take a look of tmpwatch to rotate and archive old log files. It is come with rhel.

Thanks for quick reply.

From the man page: "tmpwatch - removes files which haven't been accessed for a period of time", it is nice and easy, thanks for that.

Just wondering how to use this command to "rotate and archive old log files", do you have an example?

Sorry I mean logrotate when I say tmpwatch, I used both on a regular basis to mange log files. logrotate allows you to rotate and archive (compress) files:

/var/http/access_log {
        size 1k
        copytruncate
        create 700 xyz xyz
        dateext
        rotate 4
        compress
}

Open in new window


Then you can use remove archive (.gz) that are older than x days:
find /var/http/  -mtime +7 -name "*.gz" -print -exec /bin/rm {} \;

Open in new window
