zond plug-in v0.34c released

[johnrembo]

locate $sw_string array .... set all to "false".

I did, but how to remove the remaining text and boxes at the bottom?

hmm...i'll have to check documentation and then will reply.

Hi johnrembo,

I have a question for you.
Does the plugin try to access the rrd files in any way?

the reason I ask is because I have a problem.

For some reason the Zond plugin was not working anymore. Since I last tried I moved the rrd-files to a shared network location and the web-user does not have rights on that folder (I know, graphs are not working to but I have made a solution for that)
I tried the newest versions of zond but no success.

I have those error mesages:

Nothing else changed so can you confirm me that the web user needs access to the rrd file for zond to work?

thanks,

Can you stear me to what I might want to look at to see why Zond does not even show up on the graphs ? It will show up on the settings tab and users tab ..

but just not on the graphs. I have even tried disabling all my other graphs ...

Hi,
zond uses cacti's built-in functions and is not directly communicating with rrd files. However, if graphs can't be accessed - execution of "rrdtool_function_graph" at zond_init.php under line 188 most likely fails, and the query generated by zond_init.php for zond_process.php is faulty too.
If you're familiar with php - you could try extend beginning and end of zond_init.php with several lines that would do the following:
1) determine required rrd file (extract record from poller_output table by local_data_id - in zond_init.php it is known as ldi or l_d_i)
2) copy rrd file from shared resource to cacti's local rrd path
3) perform zond_init.php
4) at the very bottom of zon_init.php - remove temporary rrd file.

check if "users management->admin->Zond button next to charts" is marked.

[chrisgapske]

yes all boxes are checked. I have tryed both ways enabled for every user and on a per user basis.

hmm...any other plugins using same auth_realm as zond does?
first, you could try disabling all plugins except zond and see if it helps.
second, you could try changing zond's auth realm to any other number than 71, at /zond/setup.php, lines 238-240.

[chrisgapske]

I tryed changeing it to 171 and same issue. It would seem that the button just does not show up on the graph. .

And I did at try removing all other plugins but Zond.

Hi,
I have zond and SNMPTrafficeGrapher
I control same interface with both tool.
But there is some weird things:
They measure different!
Both set 5000 ms
And they show different max. values etc.
Why?
Another question, why zond shows negative values??

[johnrembo]

TFC, i remember we allreade had similar discussion on page-6 of this topic.
I was investigating this problem intensively and have come to a conclusion there are external processes that sometimes randomly terminate zonds "sleep()" function - this is not a bug, but normal unix sleep() behaviour. Because this happens randomly - it is very difficult to debug the problem. I've corrected this issuje, however, only partly - delta time between two measurements is now correct, but I was unable to force exact 1sec. 2secs etc. sleeps(). That results in some biases.
I was even wondering placing zond_process.php on another machine (which doesn't contai cacti with it's poller) - that should sovle the problem. however it's is poor man's solution.

[TFC]

Yes u right, the values are taken in different time spaces. But, if you look at the values, they are completely different. One of them has Mega other one have not. As you know, the difference between two delta time must not be like that.
And, i crosschecked this graph by using realtime plug-in. Again, it shoed megabits/sec values. But zond dont show megabits/sec.

[johnrembo]

Yes u right, the values are taken in different time spaces. But, if you look at the values, they are completely different. One of them has Mega other one have not. As you know, the difference between two delta time must not be like that.

you should take a look at my last post (image) on page-2. When zond looses 1 response - (last counter=previous counter, delta =0). Next value is (0-current_counter=hudge negative value).
zond_process.php is isolated-type script that doesn't know anything about previous values - so the only way to correct this issuje is tune zond applet by adding some intelligence. However - collecting hudge ammount of ...say...64-bit counter tables will simply kill your browser.
That's a problem

[TFC]

Too compliated.
Debuggings is hard.
I think I cant use zond in these circumstances...
Becouse shows wrong values :s

Hello!
I've installed this plugin but instead of expected graphs i only see spikes.
Any help to solve this issue is much appreciated.

I am using:
Cacti Version: 0.8.7b
Plugin Architecture Version: 2.1
Server version: Apache/2.2.3 (CentOS)
Architecture: 64-bit
PHP version: 5.1.6
I do loaded all of the Apache plugins (to be sure).
Please tell me if you need some specific configuration info.

[jenchingyang]

I just tried installing zond as well... blank windows for me too, both under firefox and IE7.

I'm running Jave 6, so that's not an issue, no erros showing in the console log for Java.

Any ideas on how to get it to work?

i'll check it asap

please, try v0.34c.
In case of failure you should supply more details - check your web server's logs for php errors, see blank window source code (ctrl+u with FF), check zond plugin with different graph templates and don't forget to read requirements at 1st post on 1st page this topic.

Hello,
I installed zond v0.34c on CentOS5.2, Used zond to view realtime graph(memory usage, load average,logged in users) for localhost(127.0.0.1) is no problem.

but unable to view other hosts. I got blank windows, try to create one new device CentOS52(127.0.0.0,same IP with localhost) and use same graph template. but the result also failed(only saw blank windows). any idea?
