I've now successfully created dozens of custom graphs, but even still, if I haven't done it in a while, it always takes me a while to get it working again to add new ones. You may have done some of this already, but here is a checklist of some items to test (roughly in order):
<br><br>1) The script that is generating the data is outputting letter-for-letter what you think it is<br> [it looks like this is correct in your case]<br>2) The proper NCV entries (if appropriate; I've only made NCV graphs) are made in
hobbitserver.cfg <br> [again, this looks good]<br>3) The two hobbitd_rrd processes have been restarted (kill -9 on them works; hobbit restarts them automatically)<br>4) The RRD file is being generated [in your case, check]
<br> a) When in doubt, it doesn't hurt to delete the RRD files and let hobbit recreate them if you see<br> some weirdness in them<br>5) The appropriate entry is made in hobbitgraph.cfg<br>6) If you're getting "hobbit graph ncv:<blah>", it usually means that there is some typo or bad
<br> reference in the hobbitgraph.cfg definition for the graph<br><br>The most common problem I've run into is human error on my part in making a typo in the hobbitgraph.cfg file. It looks like in your case, it is probably because the data doesn't appear to be getting into the RRD file properly. The fact that you're getting the "hobbit graph ncv:<blah>" on the graph page means you're mostly there. Keep in mind that
hobbitgraph.cfg is case-sensitive. The nice thing is, changes made to this file are immediate, so as soon as you make a change, you can see the effect in the graph.<br><br>Also, you don't need unique "<name>"s in the "DEF:<name>" line, so in your example above, you could use "DEF:lat . . ." for all of the 3 graphs defined. These variables are limited in scope to the graph definition they are used with.
