[Xymon] Temperature graphs

[Galen Johnson]

Maybe I missed it in a different thread but what version are you using that still references "hobbit" paths?  My rrd files don't include the colon and use a comma between test and metric.  Also, is your test firing less often than every 5 minutes?  My first attempt was firing off every 15 minutes and that was causing RRD to drop them since it was outside of the 10 minute default window.  NCV can be a bit finicky.  At that point I had 3 options:

1) check every 5 minutes (what I ended up doing)
2) use rrdtool tune after it was created to extend the default window of the rrd file
3) create the rrd myself and then let xymon populate it (which is pretty much what you have to do when you use the separate data stream).

I hid my metric inside a <!-- data --> comment like devmon does and used html codes in the status area for the viewable area.  Note, sometimes you have to wait up to 30 minutes before you see anything on the graph but you should be able to see values getting updated using the rrdtool dump utility.

I have removed the spaces and added a colon, so

   &green Routing_Engines_Temperature: 44

creates a filename that looks like:
/var/lib/hobbit/rrd/<hostname>/temperature.Routing_Engine_Temperature:.rrd

And I still get no data.
