As far as I can see there is no built in way in Xymon to monitor a log for the number of times a string has occurred in a specified time period.

Sure there is. From the client-local.cfg file comments:

"linecount:FILENAME"

Monitor the text-based logfile FILENAME, but just

count the number of times certain expressions appear.

This processes the entire file every time. It must

be followed by one or more lines with

"KEYWORD PATTERN"

KEYWORD identifies this count. You can use any string

except whitespace. PATTERN is a regular expression

that you want to search for in the file.

I use this to monitor the count of "xfer-in" and "xfer-out" messages on my DNS servers. There's already a graphs.cfg definition called [lines] that presents them nicely in a graph.
