Re: [Perfparse-users] Errors in grafh visualization

[Ben C. <BCl...@pe...>]

Morning Massimiliano,

Sorry to hear you have been having problems.

Can you tell me whether any of your graphs display?

Can you tell me if you perfparse.cfg file is correctly readable by the=20
apache system.

Did you specified the location of the file correctly on compilation.=20
Eg, if file is /usr/local/nagios/etc/perfparse.cfg

Did you use:

./configure --prefix=3D/usr/local/nagios

Do you use the History Report?  Can you tell me whether the Gant chart=20
displays on a sample History Report?

Can you try running the graph from the command prompt as follows:

# su apache  (or what ever user Apache uses.)
$ cd cgi-bin
$ export=20
QUERY_STRING=3D"?host=3Dmailsvr%2Edomain%2Eit&service=3DPOP3&metric=3Dtim=

+Service+%27POP3%27+++Metric+%27time%27=94
$ ./perfchart.png > sample.png

Can you use some safe binary reader, or vi, and look at the sample.png.=20
  Does the top of the file contain something like:

"Expires: Sun, 02 Jan 2000 01:01:01 GMT
content-type: image/png

<89>PNG"


Please let us know.

Ben.
