To be a bit more explicit...this section from the manpage:
*LOGFILE CONFIGURATION ENTRIES A logfile configuration entry looks like this: log:/var/log/messages:10240 ignore MARK trigger Oops The log:FILENAME:SIZE line defines the filename of the log, and the maximum amount of data (in bytes) to send to the Xymon server. FILENAME is usually an explicit full-path filename on the client. If it is enclosed in backticks, it is a command which the Xymon client runs and each line of output from this command is then used as a filename. This allows scripting which files to monitor, e.g. if you have logfiles that are named with some sort of timestamp. If FILENAME is enclosed in angle brackets it is treated as a glob and passed through the local glob(3) function first. The ignore PATTERN line (optional) defines lines in the logfile which are ignored entirely, i.e. they are stripped from the logfile data before sending it to the Xymon server. It is used to remove completely unwanted "noise" entries from the logdata processed by Xymon. "PATTERN" is a regular expression. The trigger PATTERN line (optional) is used only when there is more data in the log than the maximum size set in the "log:FILENAME:SIZE" line. The "trigger" pattern is then used to find particularly interesting lines in the logfile
- these will always be sent to the Xymon server. After picking out the "trigger" lines, any remaining space up to the maximum size is filled in with the most recent entries from the logfile. "PATTERN" is a regular expression.*
IIRC, you can even have multiple *ignore* entries. You should have messages in your xymon logs if the file is too big when it's fetched...also, I think you will also run up against the Xymon max data size in the server configs.
