(topic closed) ZOND plugin v0.32 released (beta)

[johnrembo]

So when I say they don't work, all numbers are 0 for an extended period of time (let's say 30 minutes). Cacti is updating the main graph with data and I can verify the IOS counters on the interface, but ZOND does not seem to report this. The graphs that are working are behaving exactly as you mentioned. The data is reported in bursts and has to be divided by 30 to make it work correctly. I am running Linux CentOS 4.3. It is just really strange that older graphs with the same template do not work, but newer graphs will.

.

ok, I managed to find-out some things.

Here's the response from ucd-snmp mailing lists about the caching problems:

The 5.x line introduced a simple build-in cache for interface statistics,
on a per-architecture basis. This is hard-coded into these early versions.
More recently, there has been a major re-write of the IF-MIB and related
groups. This includes making the timeout behaviour much more flexible.

It is now possible to set the cache timeout dynamically (for each group
individually), flush a specific cache, or flush *all* caches. This is
also common across all supported architectures, rather than being
hardcoded into particular O/S's


We suggest you try with the most recent release of the software (5.4.1).

My Zond plugin just stopped working.
How can I start the debug?

Forget about it, Java just got FUBAR.

Stupid Group policy.

well, you must have possibly performed some upgrades or other configuration changes to the system?

before proceeding futher, please try read plugin installation manual:

if you fail - submit details about your system here as well as logs, screenshots etc., and maybe community will help.

Hi, I read through this entire post and I did see a small thread where someone also couldn't find the netzond.class file. I've tried Sun's JDK 1.6, JRE 1.6 and JRE 1.5 for my browser VM but none of these work. In fact, the 1.6 version freezes on my system when I click the zond window. I have to kill the apache process. If I use JRE 1.5 I just get a little red X and a note at the bottom saying applet failed to initialize. I've attached a screen cap of this.

firstly, I would like you to check if the line
$config['url_path']='' is present in include/config.php

if yes - it should not contain any urls - for example if your cacti is at http://myhost/cacti, then find a row

$config = array();

at config.php and add
$config['url_path']='/cacti/' at the next line.

after setting this correctly, try debug zond plugin once again to be sure that no more records like
http://H_O_S_Thttps://REMOVED/cacti/plugins/zond/zond_process.php?s_i_d=536e7f6486184
are returned by the script - this row is the cause of your problems.


now, about zond_process.php problem - there has allready been a discussion on retrieving script commands it executes.

to sum up:
open zond_process.php with an editor,
uncomment line 55

//print_r($req);die;

run

php zond_process.php xxxxx

see an output:

(...)
[query] => perl /opt/cacti/scripts/linux_memory.pl MemFree:
(...)

if you are able to find [query] and able to run

perl /opt/cacti/scripts/linux_memory.pl MemFree:

- it should all work fine, otherwise - paste array it returns here (you can change snmp passwords if necesary)

you have allready mentioned this problem, but, also, it would be very nice to have more details on this subject, because "problem with network interfaces graphs" is to abstract.

are you experiencing gaps in graphs? are charts refreshing only every 30 seconds or event more rare?

i am currently working on graph template support in zond(95% finished), next step will be ucd-snmp 5.4 testing (5.1, 5.2 have problems with update intervals on some machines).

Hi John,

The web server logs show:

192.168.1.67 - - [06/Sep/2007:09:20:24 -0700] "GET /cacti/plugins/zond/zond_init.php?lgid=1&s_i_d=a95a87f488d547840d56d99
c53eab7de HTTP/1.1" 200 2696

With nothing in the error log. I tried this via HTTPS and normal HTTP but I get the same entry in the log files.

As far as the security settings for the plugin, I've tried adding the account name and password I log in with, but I get the same messages.

--------Solved-------------

Hi, after thinking about this some more, I realized it was indeed a path issue. I manually diffed each file in my install with the src packages:

scratchy zond # diff /var/www/localhost/htdocs/cacti/plugins/zond/zond_init.php zond_init.php
431c431
< <APPLET id = 'applet' codebase='".$path."' code='./netzond.class' width=$width height=$height'>
---
> <APPLET id = 'applet' codebase='".$path."' code='netzond.class' width=$width height=$height'>

Little typos make a huge difference! I had modified zond_init.php when I first installed this a week ago while troubleshooting before I posted here. Anyways, the JAVA console wasn't lying, it couldn't find netzond.class.

Thanks for the help John!

As I have allready mentioned above - this might be realated with snmp-daemon, not zond plug-in.

[cbrmig]

Everybody,

one more version of ZOND plug-in (with lot of internal changes).

This plug-in allows you to see real-time (live) charts with refresh interval of several seconds and less.

requirements:
java virtual machine compatible browser (tested with Internet Explorer 6/7,FireFox 1.5,2.0)

java runtime (1.5, 1.6) http://www.java.com/en/

some screenshots (note time scale - minutes:seconds) :













Install it like any toher plug-in. Don't forget to enable "ZOND button next to charts" for your user (or guest) under "User Management" as displayed in 3rd screenshot.

I am looking forward for your collaboration in catching-out all the bugs.

Please also share your suggestions on this thing - what features you find annoying, what other functionalities you'd like to see etc....

I already do all this, but the ZOND button is still missing in the graphs area.
I have the cacti EZ installed, mysql, php, Java 1.5..
