Thanks Gary,
I've tried deleting and rebooting several times. No joy. I just edited
the hobbitgraph.cfg in vim, and noticed that the COMMENT lines had
leading spaces, and all other lines had leading tabs. Looks like it did
not make a difference though.
I tried to run the hobbitgraph.cgi on the command line, but I don't
quite understand how to pass it the correct command line arguments.
Thanks, Larry

Subject: Re: [hobbit] Custom Graph
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):
1) The script that is generating the data is outputting
letter-for-letter what you think it is
[it looks like this is correct in your case]
2) The proper NCV entries (if appropriate; I've only made NCV
graphs) are made in hobbitserver.cfg
[again, this looks good]
3) The two hobbitd_rrd processes have been restarted (kill -9 on
them works; hobbit restarts them automatically)
4) The RRD file is being generated [in your case, check]
a) When in doubt, it doesn't hurt to delete the RRD files
and let hobbit recreate them if you see
some weirdness in them
5) The appropriate entry is made in hobbitgraph.cfg
6) If you're getting "hobbit graph ncv:<blah>", it usually means
that there is some typo or bad
reference in the hobbitgraph.cfg definition for the graph
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.
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.
Hi,
I've tried a few times to get the custom graphs to work,
but have had no
joy getting them to work. Invariably, I get the data
into the rrd, but
the graph is never drawn.
Here is a sample of the data I send to hobbit:
--->
Fri Mar 23 10:39:23 EDT 2007 - TIB RV Latency monitoring
latency : 3.291
Status unchanged in 1 days,12 hours, 9 minutes
Status message received from 146.121.201.35
<---
My TEST2RRD line has "...,GCM=ncv,RTE=ncv,SWAP=ncv"
My GRAPHS line has "...,GCM,RTE,SWAP"
I have 3 lines for NCV:
NCV_GCM="latency:GAUGE"
NCV_RTE="latency:GAUGE"
NCV_SWAP="latency:GAUGE"
I generate RRD's for each of my tests, and it looks like
there is data,
but not exactly as in the example in on Henrik's web
site:

I have the following in my hobbitgrpah.cfg:

No matter which way I configure it the graphs do not
generate, but
instead I get a small box that says:
"hobbit graph ncv:GCM"
I am currently running on a BL25P blade, RHAS4, rrdtool
1.2.15, hobbit
4.3.0-20061124.
I monitor several hundred hosts with no problem (Thanks
Henrik!), but
have never been able to get this to work. Any help is
appreciated...
