Hello,

...

I searched the web a bit and found the Xymon docs and there was mention of two ways of doing custom graphs: NCV and trends messages. NCV doesn't really suit me as my scripts have too much formatting in them and would require a rewrite to have the separate lines for values as is needed by NCV. Perhaps a rewrite is not needed. If the values to be entered in the graph are still available once the status message is build, you could add an HTML comment section to the message containing the NCVs, formatted as Xymon expects them. Additionally, you could replace the ':' and the '=' in the original status message by the corresponding HTML escape character. This will prevent the NCV module from extracting values from the original message.

That is actually a pretty interesting idea, though it ends up being about the same amount of work as using a trends message when it comes down to it (except I guess it cuts down on the number of message). I guess the NCV will use either = or : as a delimiter?

The comments in the "xymonserver.cfg" file are quite clear :-

TEST2RRD

This is also used by the svcstatus.cgi script to determine if the

detailed

status view of a test should include a graph.

GRAPH

This defines which RRD files to include on the "trends" column

webpage,

and the order in which they appear.

Hi,

as is needed by NCV. I happened to check the docs on my 4.2.3 server however and I see that the part about sending trends messages is missing. So, I've got two questions:

1. Was sending trends messages added in Xymon 4.3.x and not available in 4.2.3?

The answer to this question I found is "no, the feature was indeed available in 4.2.3 but just missing from that section of the docs."

2. At the end of this: http://www.xymon.com/xymon/help/howtograph.html ...there's a description of what to put in a trends message. There is not, however,

any description of what one does with it. My expectation is that you do the following:

xymon <display> cat trends.file

...where the trends file is like the one described in the manual (eg. starts with "data hostname.test"). Essentially, similar to sending a status message (but sending a data message instead). If this is the case, it might be helpful to have a note there in the manual, or at least a reference to the part of the manual I'm about to go hunt for that I assume mentions data messages.

And this was correct as well.

A followup question relates to the apparent requirement that you add the RRD/test name to both the GRAPH and the TEST2RRD variables in the hobbitserver.cfg. Is there any way to add the graph to just the test page and not the trends page? Why do both of these variables exist if it seems like you need both of them for it to work?
