<DIV dir=ltr align=left><SPAN class=948162418-29112006><FONT face=Arial
color=#0000ff size=2>You might need to write your own log checker to generate
something that Hobbit can catch. Hobbit was not really designed to handle
large log file volumes. The MAX variable, if I remember correctly, tells
how much data the Hobbit client should sift through. Once this limit is
reached, it just pumps what's left -- but I may have that
wrong.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=948162418-29112006><FONT face=Arial
color=#0000ff size=2>One way to do it might be to "tail" the log file and pipe
the data through grep on the way to another log file, which you can then have
Hobbit watch. The problem you will have is keeping up with the log files
as they rotate. Perhaps someone else on the list can pipe up with how that
can be done -- maybe by monitoring the file name associated with the
inode? Of if there is no data for x amount of time, switching? All
this may be more than a simple shell script can handle, so you may need to write
something in Perl or C or whatever.</FONT></SPAN></DIV>
