That’s a great tip! That’ll let me quit using a secondary data message for NCV.

Thanks!

If you are referring to the web page output, just wrap the ncv area in html comment tags... <!-- NCV Data foo: 7 bar: 34 -->

This will still let the data be parsed by NCV but will hide it from the browser and not clutter that screen.

I know there’s a tag that I can include in status messages so xymon ignores all the text between the tag and /tag, so that the values don’t get picked up by the NCV engine. But I can’t find that tag anywhere. Can anyone remember what it is?

Thanks!

Looks like this is formally documented in xymond_rrd(8) man page (and there's more options to use too):

   Any  lines  in the status message prepended with a "<!-- ncv_skip

-->" will be skipped by the module. This can be used to prevent unneeded RRD files from an existing dataset from being created.

   A line prepended with a "<!-- ncv_skipstart -->" will be ignored,

along with all subsequent lines until a line starting with "<!-- ncv_skipend -->" is found, at which point processing will resume. This can be used to ignore explanatory or other text with a mostly-ncv message.

   "<!-- ncv_ignore -->" can be used to ignore certain text at the

beginning of a line, up until a closing '</-->' tag on the same line, at which point the line will continue to be processed as usual. Wrapping is not supported; but skipstart/skipend can be used to handle multiple lines.

   A bare "<!-- ncv_end -->" on its own line will stop further NCV

processing of that message.

   All of these ncv_ terms are case-sensitive. Note that if you have

full control over your NCV output, it is most efficient to have NCV data near the top of your message and use "<!-- ncv_end -->" once your data is complete.

If you want to have RRD graphing ignore the data, but still display it on the web page:

Use

<!-- ncv_skip -->

at the start of the line to skip the whole line.

Or use

<!-- ncv_ignore --> </-->

to ignore only certain parts of the line. I'm not sure if this works for multiple lines or not (I've only used it to ignore parts of a line).

Hope this helps!
