[hobbit] HTTP test

[Vernon Everett]

Hi Henrik

Thanks for the reply.

I rechecked my script.

What I sent you was my debug output (for human consumption only) and is
from the & lines.

       while read TABLESPACE VAL
       do
           [ -n "$OUTVAL" ] && OUTVAL="$OUTVAL:"
*          echo "DS:$TABLESPACE:GAUGE:600:0:100"
&          echo "DS:$TABLESPACE:GAUGE:600:0:100"  >> /tmp/newtest.out #
test 
                                                      # stub remove
later
          OUTVAL=$OUTVAL$VAL
       done < /tmp/stripped
     rm /tmp/stripped
*    echo "tablespace.rrd"
*    echo "$OUTVAL"
&    echo "OUTVAL=$OUTVAL" >> /tmp/newtest.out  # test stub remove later
   
The * lines are machine-readable output, and should end up in the .rrd
files.

But it isn't even trying to write a .rrd file.

Thanks for the tip about the hobbitgraph.cfg.
I have created an entry in the .cfg, but until I get some data into the
rrd files, it will still not display anything. L

Or does the script and the contents of the hobbitgraph.cfg have to be
correct before it will start writing a .rrd file?

Cheers
    V

The first part with all the "DS:..." defs look OK, but the last line

is wrong.

 

Right after all the "DS:.." lines you must output the filename for the

RRD file - "tablespace.rrd" or whatever suitable name you can think of.

 

Next goes the line with the values you've parsed. Leave out the

"OUTVAL=" bit, it should ONLY be the values - nothing else.

 

And did you remember to setup a definition in hobbitgraph.cfg how this

graph should be displayed ? Quoting my man-page:

 

      Apart  from  writing  the  script, You must also add a section to

      hobbitgraph.cfg(5) so that hobbitgraph.cgi(1)

      knows how to generate the graph from the data stored in the

      RRD file.  To make the graphs actually  show  up  on

      the  status-page  and/or the "trends" page, add the

      name of the new graph to the LARRDS and/or GRAPHS setting in

      hobbitserver.cfg(5).

Thanks, will do if I manage to get down under sometime :-)
