0.83a, Graphs just hang.

VeSS · Post by **VeSS** » Thu Sep 18, 2003 12:17 pm

Hi all. Im running 0.83a of Cacti on a Win2K server, with all Service Packs. The webserver is:

Win2K
Apache 1.24
PHP 4.33
Mysql 4

I can poll hosts, and get information. When i do a graph debug i can see the graph, and it has data. But when clicking on the "GRAPH" tab, cacti freezes. Any ideas? I went over the install guy over and over. Everything is right.

Fellow Cacti travelers on the Win32 side of the stream.

Here is some insight on no graphs being displayed.

Let me know if you see the same results.

Thx

Installed is Cacti 0.8.3a.

Supporting applications:

Apache 2.0.47-win32,
PHP 4.3.3-win32,
ActiveState Perl 5.8.806-MSWindows

The platform system is Win2k server/sp3 + IE6/SP1.

An interesting REPEATABLE sequence that does display a graph.

1. Launch Cacti's entry page & login as admin.

2. Choose the graph's tab.

3. Click the second tree( in my case a successfully polled router)

Watch the lower left corner of your browser, see the "graph_view.php?action=tree..."

wait 10 seconds and click on the browser stop button.

Ta Da we have a graph, it is consistent with the desired parameters.

So I turned on activestate's komodo IDE and ran "graph_view.php?action=tree..."

up came from within "cacti\include\auth.php"

PHP Warning: session_start(): Cannot send session cookie
- headers already sent in C:\Apache2\htdocs\cacti\include\auth.php on line 40

To confirm that it is a real issue, thanks to Welling & Thomson pg 435, open a file like phpinfo.php in the htdocs/cacti directory:

This is what I see

.........................................Web display of http://traffic.webnslookup.com:8080/cacti/phpinfo.php
test1
this is PHP.

<?PHP

/* Insert your PHP code here */

echo "this is PHP.<br>";

session_start();
session_register("sess_var");
$sess_var = "hello world";
echo "the contents of \$sess_var is $sess_var<br>";

phpinfo();

?>

</BODY>

Let me know if any of you see a similar result.

I am running windows XP and also have problems displaying the graph. When opening the graph display the browser hangs.

The problem with the sessions can be solved by changing the session.auto_start to 1 in the php.ini.

If you solved the problems with the graph I would be very thankfull if you posted it.

Let me know.
