You could always output the results of dmesg at boot-time to a file -
adding something like this:
dmesg /var/log/dmesg.boot
to /usr/local/etc/rc.local.
This already happens, to /var/run/dmesg.boot
Not sure how to account for the discrepancy - presumably it's not
counting memory that can't be used under FreeBSD (possibly the 'wired'
memory, for the kernel, and some other stuff.) If you really need the
real total memory on the machine (as opposed to what's available to the
operating system,) you should probably parse /var/run/dmesg.boot (which
isn't difficult - just grep for 'real memory' and take the fourth field
with e.g. awk '{ print $4 }'.)

showing total/free memory
Greetings, What is the best/easiest way on FreeBSD 5.1 to show the total and free amount of memory (at any given moment in time)? I am setting up MRTG and at the moment I am parsing /var/run/dmesg.boot and the output from `top -b -d 1` to get total and free memory respectively, but I hope there is an easier way. tia Dave ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Try vmstat instead. Thought of that. According to the man page, vmstat shows, for memory: avm active virtual pages fre size of the free list Does the size of the free list correspond to actual free memory? I wasn't sure whether that was the case or not. Also, it's a case of parsing the output from top or parsing the output from vmstat - I had hoped there would be a simple command that would show memory state :) Dave ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
