I was getting the same error as X505 and then I noticed it was on all graphs where Area was set to Last instead of average. Now maybe it is because of a misunderstanding I have in Cacti but I want all my graphs to display the last value and not anything averaged so I set them this way. Is this not the correct way to handle this? Should this be a valid entry for Zond to handle in a graph template? Even when I change the templates and the graphs come up the chart icons are only showing red x's =(. I could not help but notice X505 also has his set to Last instead of average as well on the screen shot he included.

Thanks!

No, don't adopt your graph templates to zond plug-in. I've almost finished new version which should handle complex templates easily. As soon as I will fix some pending security issues - I will upload it.

Hi,

i have two server with cacti and plugin zond.

The first has no problem ... when i click on zond i get the data in real time ... apart from the network interfaces.

On the second instead for all the graph i can't obtain any graph... the popup is blank and has no data.

Can you help me?

I have the same results, empty pages using Zond on Linux

The assumption that follows is wrong, the output on / is normal it was executed on the console and not in a Browser. Please ignore it. Correct reason a few posts lower

The problem probably lies in this string

Code: Select all

codebase='http:///plugins/zond/' 
and
...true,1500,http:///plugins/zond/zond_process.php?s_i_d=c5kup0o07jkp9s3it40lfo9lq4&tasks=YTo1OntzOjQ2OiIzN...

If I check the setup.php file I noticed that the $config['url_path'] is taken from the cacti config.php variables. Due to the fact that my cacti runs in his own URL I use "/" as value for this string, thus the faulty URL in the Zond java code. Irt seems that the code does not use the real URL value.

Code: Select all

 $INITIAL_PATH = $PROTO.$_SERVER['HTTP_HOST'].(!empty($config['url_path']) ?
substr($config['url_path'],0,-1) : '');

I'm facing quite the same issues as kwabbernoot. It's a non-standard directory here, config.php is set to reflect this url, but $_SERVER['HTTP_HOST'] (zond_init.php line 261 in zond 0.31) seems not to be resolved correctly (well, in cli context this should be normal, but the web page is simply empty and no source code is shown).

To quote zorrosam, my Apache error log shows the same

Maybe I made a mistake in my previous post, after posting it is came to my mind that the URL in the post maybe set to "/"because I was executing the commands in my console and not via the browser where the zond scripts take some info from the http session.

The error in my case is due to the fact that my php.ini does not activate the setting "register_argc_argv", setting this to "On" enables the graph.

On most PHP systems however this settings is not activated in the php.ini file, this due to security/performance problems.
My personal advise towards PHP scripting is that you either develop your program that they do not need the functionality within the php.ini file or activate the global setting within your PHP scripts. this way other PHP environments on the same machine are not impacted.
Use the "ini_set" directive see URL http://de3.php.net/manual/en/function.ini-set.php
Unfortunately "argc-argv" settings can not be set by this option

The graph builds now, but I get the following output in my httpd error log

Code: Select all

Setting register_argc_argv to on in php.ini solved the issue.

Nice find. While I personally agree with most of your statements, I do not agree with activating them inside php scripts. IMHO, the security impact is too big and there should not be a need for it (without having investigated this very issue here)

Hello, firstly thanx for the accurate shot. I am deeply drowned in elimination of several previous problems so this "blank graphs" problem was still in queue.
I am trying ZOND on FreeBSD and Debian machines, where both php installations have register_argc_argv enabled by default.
Truth, I heard this is kind of security gap, but so is register_globals, or shell_exec. Moreover, cacti's cmd.php and script-server also uses this module. Currently I won't be able to force ZOND to work without this (maybe only in future releases), that also makes me to keep debugging as flexible as it can be.

Errors and notices are realy caused by command line debugging. I will try to eliminate them.

About last error - it seems part of string is missing while executing a command. Does this happend with all the graphs or only some special-ones (like those realated with external scripts or script-server) ?

Well, that's the strange thing, the graphs are the Interface ones "Traffic bits/s" that are standard in Cacti and are using SNMP.

I actually added some screenshots where you will see:
- The actual graph in Cacti
- The Zond Graph
- Apache error log

This one taken from a Windows Device fails and generates the errors: see attached image zond_graph_error.jpg

This one, taken from a Cisco router works and thus generates no errors:
see attached image zond_graph_ok.jpg

this issue is resolved in Zond v0.32
