Yes, that's a start.
Thanks,

Wouldn't that work for you at least at this point?

Yes -- you only need one % at the beginning of your string to
tell
Xymon you are going to use a regular expression. You do not need
the other % unless they are expected to appear in the log.
When using a regular expression, the | character means "or". So
if
your example will "fire" if any message contains and of those
words. Also you seem to be using * by itself, which means "match
the preceding 0 or more times". Normally we use "dot star" ".*"
to
mean "match anything no matter how long."
Regular expressions are a bit of a mystery, but are very
powerful.
Xymon uses Perl-compatible regular expressons (PCRE) so you might
be
able to Google some examples.
If you are searching for "Out of memory" in a log file, you can
use
"%Out of memory" as your regex string. I do not remember how you
deal with spaces in the string and the Xymon help is not helpful.
One way to do it would be to change your spaces into \s+ so it
would
be %Out\s+of\s+memory which removes the embedded spaces (so the
Xymon parser does not think part of your regex is some other
token
on the commend) and also means that you will match of the is at
least one whitespace character between each word -- slightly more
robust than using a single space.
I know the above is a jumble, but if you will post the exact
string
you want to match we can help you create the matching expression
to
help you get the hang of it.

Right now looks like this:
LOG /var/log/messages
%failure*|%failed*|%error*|%Warning*|%memory* Color=Red
But if I type
LOG /var/log/messages
%failure*|%failed*|%error*|%Warning*|%out
of memory* Color=Red
I'm getting all the messages that have one of these words:
out
or of or memory somewhere in their string.

Try making it a regex (with % prefix) instead of "simple"
expression.

I think it's:

LOG /var/log/messages "out of memory" COLOR=red

Hello all,
I am trying to set up an alert to search for exact word
patterns
in
/var/log/messages. For example: "Out of Memory"
Any help would be appreciated.
