Any way to get time/date info on dmesg entries?
I would like to know the time/date of various syslog/dmesg entries, such as when the disks spin up and down.
On my Fedora linux machine, I can get the timestamps by looking at /var/log/messages.
How can I get similar info on the DNS-323? (note I didn't see any relevant syslog files in /var/log?
Is turning on syslogd.sh the right way or can I get that info without doing that?

Code:
sh /ffp/start/syslogd.sh start cat /var/log/messages

Re: Any way to get time/date info on dmesg entries?
I assume that there is no automatic logrotate type facility. So, I imagine one needs to be careful that /var/log/messages doesn't fill up the rootfs space if the device remains up for a long time.
I can imagine two potential solutions:
1. Add a cron job to trim /var/log/messages (and potentially compress and transfer the trimmed part to your HD)
2. Have syslog write to your HD rather than to the rootfs. This may create a conflict with the hard-disk spindown notification (unless you write to a USB stick instead) since every time the HD spins down it may need to spin up again to write to /var/log/messages.
Does anybody have any experience or recommendations?

It's busybox syslogd/klogd. rotation is built-in, defaults are:
Code:
root@bob:~# busybox syslogd --help
...
Options:
...
-s SIZE Max size (KB) before rotate (default=200KB, 0=off)
-b NUM Number of rotated logs to keep (default=1, max=99, 0=purge)Offline

Re: Any way to get time/date info on dmesg entries?
ok, now if /var/log/messages reaches 200KB, it :
a) will be moved (to which location?), a new empty /var/log/messages file will be created?
b) a new empty /var/log/messages file will be created?

It will rename the old file to "messages.0" and start a new "messages".
