<p>When I ran into this, someone suggested that I replace the colon with it's html character code equivalent (%3A). Since xymon parses the colon, it should ignore the the html encoded representation but the browser will still display it...it's a complete hack
but it should work (ultimately, I chose not to include the time stamp since that is in the page already).<br>

<div>As a request for enhancement, I think it would be useful to have an option to use a regexp to extract data from the status, one for each variable.</div>

Unfortunately, there isn't a way to do either of these at the moment. I'd<br>
considered a data parser that looks for a hidden HTML comment marker for<br>
lines to process (and ignores the rest), but it's not quite present yet.<br>
<br>

The easiest way to do this would be to add a --filter= option to the<br>
xymond_channel command line for the xymond_rrd process that's handling the<br>
*status* channel, but not the data channel.<br>
<br>
There's a CPU load hit for doing so (since now you're doing a PCRE on each<br>
message), however it may not have much of an impact depending on your<br>
message volume.<br>
<br>
<br>
> * Might there be some other mechanism entirely?<br>
<br>
Generally, speaking for more advanced RRD submission, the 'trends' message<br>
can be a useful data payload which is read directly by xymond_rrd. The<br>
advantage there (aside from more direct control) is the ability to send<br>
data points for multiple graphs at once, which could outweigh the expense<br>
of another message transmission.<br>
