Custom Graph

Fri Mar 23 16:31:16 CET 2007

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:

[GCM]
	TITLE GCM Latency Monitor
	YAXIS Micro Seconds (uSec)
	DEF:lat=GCM.rrd:latency:AVERAGE
	LINE2:lat#00CCCC:uSeconds
        COMMENT:\n

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...
