[hobbit] RRD graphing not showing up

Wed Jul 12 15:51:07 CEST 2006

Hi again,

FYI, I finally found a solution to my problem.  If anyone of you have the 
same issue.

Any AIX 5.3 "new" installation were not working properly (RRD Graphs not 
workking).  Any servers that were migrated from an earlier version (ex: 
AIX migrated from 5.2 to 5.3) where functionnal.  I spent some time 
playing with the source of hobbitgraph.cgi and found that the parse of the 
query was not working (it only catched the host, all other variables were 
not parsed)

At the end, I upgraded rrdtool to latest.  I installed 1.2.13. and 
re-compiled Hobbit.  And it started working.  I have no clear 
understanding of the cause but this worked out.

[hobbit] RRD graphing not showing up

Hello,
I'm still on this problem.  By testing manually hobbitgraph.sh, I received 
the following output:
Content-type: text/html
<html><head><title>Invalid request</title></head>
<body>Invalid request - no host or service</body></html>
Does someone have an idea where I should look?
Here is the other details I already sent.
The graphs do not show up on one Hobbit server I installed on AIX. All the 
other hobbit servers I installed on AIX 5.2 and 5.3 do work fine. I used 
the same procedure for installing Hobbit (same pre-reqs). All the pages 
shows up properly but the graphs images are not produced. 
The server is on AIX 5.3, running 64 bits kernel. I tried many things 
following what I found in the list but without success. Here is what I 
tried already: 
- Tested manually hobbitgraph.sh, with the Apache user (REQUEST_METHOD, 
REQUEST_URI, etc). It return data. 
- Recompiled a few times using different options 
- I saw the list thread about problems on HPUX and 64 bits compilations. 
So I tried recompiling with my server in 32 bits and same problem 
- rrd files gets populated and rrdtool dump is working 
In my apache error log, I have the following: 
Premature end of script headers: /home/hobbit/cgi-bin/hobbitgraph.sh 
In my rrd-data.log, I have (I don't think it matters) 
Internal error: Duplicate match ignored 
Any ideas?
