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.
