Limited amount of log data

[ken.schweiker at faa.gov]

Hi,
Trying to set up xymon to capture log data. Once I changed the permission
on the var/log/message file, I got -some- data. I am taking the defaults
with xymon 4.2.3. I might appear that I only get to see the last 30 minutes
of log data. Can this be increased?

Second, why does it say No entries in /var/log/messages.
Thanks.
