Re: [hobbit] No graph from RRD data

I suggest that you insert spaces usage : 1

Now I have a graph on the status page!

It's just now showing the right value. It should be "1" and the graph is showing "0".
Here's the status page from the test:
----------
green 22-11-2006 11:22:32,48

usage:1
-------------
I stripped the rest for debugging the right stuf.
So I guess your right that RRD isn't picking the right value.....

The RRD isn't picking up the right value, you put
NCV_usage="usage:GAUGE" but in the rrd you're getting :

<ds>
                <name> usage </name>
                <type> DERIVE </type> <-- this is the default

Can you please send the output message hobbit displays for
this status.
Also do you see a hyperlink at the bottom of the status
saying anything
like ncv status graph?
Jason.

Hi all,

Following problem keeps me busy several days now....

I'm using hobbit 4.2.0.

I want to create a custom graph and use ncv to create the rrd file.
I receive data from a custom script on the client, a column "usage"
appears on the hobbit display.
The rrd file is created, but no graph is created, what's wrong??


In the data is a parameter in the following format:
usage:1

hobbitserver.cfg is configured:
TEST2RRD="cpu=la,disk,.....,usage=ncv"
GRAPHS="la,disk,......,usage"
NCV_usage="usage:GAUGE"

This works fine, a file named usage.rrd is created.

Dump from usage.rrd:
<!-- Round Robin Database Dump -->
<rrd>
        <version> 0001 </version>
        <step> 300 </step> <!-- Seconds -->
        <lastupdate> 1164183687 </lastupdate> <!-- 2006-11-22 09:21:27
CET -->

        <ds>
                <name> usage </name>
                <type> DERIVE </type>
                <minimal_heartbeat> 600 </minimal_heartbeat>
                <min> 0.0000000000e+00 </min>
                <max> NaN </max>

                <!-- PDP Status -->
                <last_ds> 1 </last_ds>
                <value> 0.0000000000e+00 </value>
                <unknown_sec> 0 </unknown_sec>
        </ds>

hobbitgraph.cfg is configured:
[usage]
        TITLE Usage
        YAXIS # Users
        DEF:u=usage.rrd:usage:AVERAGE
        COMMENT:\n
        GPRINT:u:LAST: \: %5.1lf (cur)
        GPRINT:u:MAX: \: %5.1lf (max)
        GPRINT:u:MIN: \: %5.1lf (min)
        GPRINT:u:AVERAGE: \: %5.1lf (avg)\n

Result: no graph is being displayed, what is missing or am I doing
wrong?

Regards,

Johan Rutten
