Re: [hobbit] help - still problems to see rrd graph

Hi Marco,

Have you tried to look at the rrd file using rrdtool dump file.rrd ? this could give you an indication if its the rrd file that is the problem or the cgi program.

I am running RHEL 3 update 4 with this configuration

hobbit 4.1.2p1
rrdtool-1.0.49-1.1.el3.dag
zlib-1.1.4-8.1
libpng-1.2.2-25

which works.

Hi all,

perhaps my problem is connected to the rrd version ( i use rrdtool-1.2.12), or some build options that i used to install
rrd is not compatible to hobbit?
i follow these instructions to build rrd


http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/doc/rrdbuild.en.html

need helps....


Marco

Searching in mail archive i found that, to test cgi, i need also to set
REQUEST_URI.
So i try :

export REQUEST_METHOD=GET
QUERY_STRING="host=...."
export QUERY_STRING
REQUEST_URI="http://localhost/cgi-bin/hobbitgraph.sh?${QUERY_STRING}";
export REQUEST_URI
./hobbitgraph.sh


the new output seems normal, but i can't see graphs:




<tr>
<td align="left"><img
src="http://monitor.regione.toscana.it/cgi-bin/hobbitgraph.sh?host=monitor.regione.toscana.it&amp;service=la&amp;graph_height=120&amp;graph_width=576&amp;disp=hosta&amp;nostale&amp;action=view&amp;graph=hourly";

alt="hourly graph"></td>
<td align="left" valign="top"> <a

<img src="/gifs/zoom.gif" border=0 alt="Zoom graph" style='padding: 3px'>
</a> </td>
</tr>
<tr>

no error on cgierror.log. I try to reinstall libpng 1.2.8 zlib 1.2.2, and
recompile hobbit.
My ldd output for hobbitgraph.cgi is :
libpcre.so.0 => /usr/local/lib/libpcre.so.0 (0x00e86000)
librrd.so.2 => /usr/local/rrdtool-1.2.12/lib/librrd.so.2
(0x004c2000)
libpng.so.3 => /usr/local/lib/libpng.so.3 (0x0090e000)
libc.so.6 => /lib/tls/libc.so.6 (0x0098f000)
libm.so.6 => /lib/tls/libm.so.6 (0x00480000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00fe5000)
I try also to add in ld.so.conf /usr/local/lib, where is libpng.so, and run
lidconfig:

ldconfig -v | grep libpng
       libpng.so.3 -> libpng.so.3.1.2.6
       libpng12.so.0 -> libpng12.so.0.1.2.6
       libpng12.so.0 -> libpng12.so.0.1.2.2



any suggestions ?

M.

You need to set REQUEST_METHOD=GET also.
