graphs_view.php broken in dual pane tree view

[jmjones]

If you are having the pesky error that I have been referring to in this post. I have altered a section of code found in include/top_graph_header.php

The code block is as follows
$first_branch = find_first_folder_url();
if (!empty($first_branch)) {
if(!empty($_REQUEST["ret"])){
$mystring = "&ret=yes";
$first_branch = $first_branch . $mystring;
header("Location: $first_branch");
}
print "The first branch was not empty" .$first_branch;
}

All it does is keep track of whether or not it is looping by throwing a var in the querystring

Hope this helps

Does this problem only manifest itself when "Expand Hosts" is selected from "Graph Settings"?

I have replaced my code with the code in the distribution, and found that there was no difference when I enabled the expand hosts option.

[jmjones]

There is an error message when the expand hosts option is enabled.
"CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers."

real helpful error message don't you think. I haven't a clue what causes this, but the code I submitted earlier fixes this issue as well.

Sending myself a note to explore you patch.

Thanks for working on it!

Tony,

Please crank out a patch. Need it deparately.

jmjones,

Ok, well after review of the current code, the session variable

Code: Select all

$_SESSION["sess_has_viewed_graphs"]

takes care of if the redirection happens again. This would lead me to believe that you maybe having a cookie or session problem. I only see one redirect when I sniff traffic when viewing the graph page initially. Btw, was using the database you sent me a while ago to test, so I have the same hosts.

Larry, this is not the solution to the issue with the graph page being slow, so I don't see a patch at this time.

Sorry man, still searching for the badness in the code....

Hi people,,, i want to know if only changing the timeout on php.ini the dual pane will working correctly??...

Regards...

[jmjones]

This error is kind of tricky, changing the timeouts may help - they have for some. Tell what server makeup you have and you will get more help. I have been battling this problem in win 2k3, php4 and mysql4. My server is very fast and I think that has something to do with it. Does your server have multiple processors? Mine does.

[rony]

It helps, with largers installations.

It's just masking a larger issue that I'm trying to find the time to fix.

I have 2 differents severs in linux with cacti 8.6c(probe)
in one of the servers(ServerA) the dual pane work perfect..
And in the other server not work..
I take the same tar.gz for installation.

Server A:
Red Hat Linux Advanced Server
Apache/1.3.23
mysql Ver 11.15 Distrib 3.23.41, for redhat
2 - cpu - Intel PIII 1.2 GHz

Server B:
Fedora Core release 2
Apache/2.0.51
mysql Ver 11.18 Distrib 3.23.58, for redhat
2 - cpu - Intel(R) Xeon 2.4Ghz

[dj_seijin]

I put a frontend to access my internal cacti (ServerA )and i can see the dual pane...
Im really confuse where is the problem!

[jmjones]

Look at the code snippet I suggested above. If you are familiar with php, comment out the original code and insert the snippet from above. Let me know if that works for you. Also, someone else suggested that there may be an issue with the "Expand Hosts" option. You may want to try different variations of this option. Make sure that when you make a change that you close your browser out. This will make sure that all of the server variables will be "Nulled Out" and you can get an accurate idea of what changes did work and what changes didn't

As I say, I am still looking for a "Better Solution" to this problem, but to get that I need to find where the problem really is. Please share all the information that you discover so a proper patch can be created.

Roni and The Witness rule. They will save the day, I just know it--- Right???
