dmesg

[MikeL_4]

Is there a way for dmesg to ignore certain messages ??

I have some database file systems that are always 100% full, and dmesg keeps recording the problem, which I don't care about ....

Thanks

From the man page:

"If the - argument is
specified, dmesg computes (incrementally) the new messages since the
last time it was run and places these on the standard output. This is
typically used with cron (see cron(1)) to produce the error log
/var/adm/messages by running the command:

/usr/sbin/dmesg - >> /var/adm/messages

every 10 minutes."


You could adapt this technique to filter out the unwanted messages (with "grep -v") and check the /var/adm/messages file rather then dmesg itself.
