[Perfparse-users] "Error 500" in version 0.104.1

[Gili L. <Gi...@so...>]

Hi All,

I'm trying to use the perfgraph (0.104.1), but I got "Error 500". Only if a
parameter is passed to the script...
If I execute this cgi by command prompt I get the HTML. And if I export the
"QUERY_STRING" it works goes as well...
But if I do this thing by the browser I get the Error 500.

This occurs in ver 0.103.2. the only version I tried this didn't occurs is
ver 0.100.1.

I inserted a line in the perfgraph.c to debug this (as I read in this list).
------
fprintf(stderr, "%s:%d\n", __FILE__,__LINE__);
-----
this is the output from the error_log

<---snip--->

[Thu Dec 02 17:47:15 2004] [error] [client 10.1.1.1] malformed header from
script. Bad header=perfgraph.cgi: perfparse.cgi, referer:
http://10.1.1.1/nagios/side.html
[Thu Dec 02 17:47:15 2004] [error] [client 10.1.1.1] perfgraph.c:67,
referer: http://10.1.1.1/nagios/side.html
<---snap--->
Line num 67 is the first line in the mail() function.
I use Apache 2, MySQL 4.1.7, gcc 3.2.

What I did wrong?

Hi Gili,

Please remember that the program name changed from perfgraph.cgi to 
perfparse.cgi.

There have been two users before you who had the same effect.  The menu 
would show but none of the calls which accessed the database.

I know one user reported 'it just started working'.  I am not sure how 
this was resolved with other user.  If one of them is reading, please 
let us know :)

If you use your debug, please fflush(stderr) after calling.  A crash can 
destroy the buffer.  Also if you use this debug, add it *only* after the 
initial header:

	printf("Expires: Sun, 02 Jan 2000 01:01:01 GMT\n");
	printf("content-type: text/html\n\n");

Or you will get 'malformed header from script'. or 'Premature end of 
script header'.

You can populate the QUERY_STRING from the command line, but ensure you 
'su' to what ever user your http server is using to execute the scripts.

You may try setting the SUID bit on the script:

# chown root.root perfparse.cgi
# chmod ug+s perfparse.cgi

This is *not* a good way to run, but might help you find your error.

Please also ensure your database details are correct in 
etc/perfparse.cgi and the etc directory this is located in was compiled 
into the program using:

--prefix=/usr/local/nagios

And this file (perfparse.cfg) is entirely readable by the http server user.

Please let us know...

Ben

Sorry, error.

"Please also ensure your database details are correct in
etc/perfparse.cgi and the etc directory this is located in was compiled

Should read:

"Please also ensure your database details are correct in
etc/perfparse.cfg and the etc directory this is located in was compiled

[Perfparse-users] Annoucements

Dear PerfParse Users,

Important news about new PP version 0.104.2 and new PP web site 
wiki.perfparse.org is now available on our perfparse-announce new group:

[Yves M. <yme...@li...>]

Ben answered to this mail but I'm not sure.
I would like to add that you can also add your own debug log easily :

FILE*logfh;
logfh =3D fopen ("/tmp/my_own_error.log", "w+");
fpritnf(logfh, "%s:%d\n", __FILE__, __LINE__);
fclose(logfh);

With this, you have easier access to a log file, and you can put debug ma=
rks before the
CGI header.

Please try on 0.104.2 and perfparse.cgi instead of perfgraph.cgi that was=
 renamed.
