Nagios Plugin for Cacti (NPC) 2.0.4

[icetoad]

I grabbed the files and tar'ed them. I put them here if anyone just wants to download 2.0.4: http://www.scsorlando.com/files/npc2.0.4.tar

Many thanks the original developer for restarting this, i hope you come back!

I love you tag line quote. Funny. It's not all fiction, but the modern (aka AD 400) church has aggressively attempted to turn it into that.

I had the same issue with the grid being empty, i followed the quickstart guide and your commands to the T and while it had populated data in the hosts and services tables, the status tables were empty. I ran the following update and bam, grid started filling out.

I took a look at the setup.php for npc, seems the columns are not in the create_table statements. So if you are not getting populating on the NPC page, make sure to check your tables for the following columns, if they arent there, run the statements below.

Finally fixed the issue myself.

The SQL doesn't create the needed default columns....

I ran the following to fix the database and actually get somewhere...


ALTER TABLE `npc_hostchecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_hoststatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_servicechecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_servicestatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_statehistory` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_eventhandlers` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_systemcommands` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_notifications` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

hi all,

I am unable to get NPC working. I'm using
- Cacti 0.8.7g
- Plugin Architecture Version 2.8
- Solaris 10

After following the instruction to install NPC, the NPC tab doesn't show up in the Cacit. (I did edit the global.php to include $plugins[] = 'npc';) Moreover, when I tried to access npc by http://someserver/cacti/plugin/npc/npc.php, I got the error

"You are not permitted to access this section of Cacti. If you feel that you need access to this particular section, please contact the Cacti administrator"

It didn't work even I change the NPC directory to 777 permission.

Any help is greatly appreciated!!

Many thanks!!!

Hi all,
for anyone trying to get this working on FreeBSD (as I have been for the past few hours), you might need to reinstall the package with "event broker" enabled.

cd /usr/ports/net-mgmt/nagios
make rmconfig
make deinstall
make reinstall

When prompted with the options screen, make sure the following line is ticked:

[X] EVENT_BROKER Enable event broker functionality

Hi, I have a problem with my npc plugin on cacti.
I have tryed a lot of tips from this thread but I can't resolve my problem.
This is my configuration:
- SO Linux Centos 5.5
- Cacti version: Version 0.8.7g
- Plugin Architecture Version: 2.8
- Clog 1.6
- Monitor 1.2
- Settings 0.7
- Boost 4.3
- Npc 2.0.4
- Rrdclean 0.41
- Thold 0.4.1
- php-pdo-5.3.5
- json version 1.2.1
- Nagios 3.2.3
- ndoutils 1.4b9

Nagios work well; this is the output of log:

[1298482732] Nagios 3.2.3 starting... (PID=21436)

When I enter in the NPC tab of my cacti, Nagios seems On and everything on the top is green but there is nothing in the Dashboard tab and I can't open new tabs (see attached image).

In my apache log appear this message everytie that I enter in the NPC tab:

[Wed Feb 23 19:10:30 2011] [error] [client xxx.xxx.xxx.xxx] PHP Notice: Undefined index: action in /media/volumen/cacti/plugins/npc/top_graph_header.php on line 95, referer: http://cacti.xxx.com/settings.php?tab=npc

I think is a problem of my db but I don't know what I can do.

Thanks in advance.

I solve my problem (or only a part of it)!!

I create 3 tables in my db with those querys:

CREATE TABLE `npc_host_graphs` (`host_graph_id` int(11) NOT NULL auto_increment,`host_object_id` int(11) NOT NULL,`local_graph_id` mediumint(8) unsigned NOT NULL,`pri` tinyint(1) default 1,PRIMARY KEY (`host_graph_id`),KEY `idx1` (`host_object_id`)) ENGINE=InnoDB;

CREATE TABLE `npc_settings` (`user_id` mediumint(8) unsigned NOT NULL,`settings` text default null,PRIMARY KEY (`user_id`)) ENGINE=InnoDB COMMENT='NPC user settings';

CREATE TABLE `npc_service_graphs` (`service_graph_id` int(11) NOT NULL auto_increment,`service_object_id` int(11) NOT NULL,`local_graph_id` mediumint(8) unsigned NOT NULL,`pri` tinyint(1) default 1,PRIMARY KEY (`service_graph_id`),KEY `idx1` (`service_object_id`)) ENGINE=InnoDB;

Now I see the tabs and my Dashboard work but sometimes it not refresh the view and in the apache log I can see this lines:

[Wed Feb 23 19:33:03 2011] [error] [client xxx.xxx.xxx.xxx] PHP Notice: Undefined variable: temp in /media/volumen/cacti/plugins/npc/controllers/servicegroups.php on line 206, referer: http://cacti.xxx.com/plugins/npc/npc.ph ... drawLayout

Any ideas?

I'm getting the following error with the npc plugin. The error was taken from apache2 error.log after clicking on the npc tab.

PHP Fatal error: Uncaught exception 'Doctrine_Manager_Exception' with message 'Could not parse dsn' in /usr/share/cacti/site/plugins/npc/lib/Doctrine/Manager.php:335\nStack trace:\n#0 /usr/share/cacti/site/plugins/npc/lib/Doctrine/Manager.php(350): Doctrine_Manager->_buildDsnPartsArray('mysql://cacti:c...')\n#1 /usr/share/cacti/site/plugins/npc/lib/Doctrine/Manager.php(214): Doctrine_Manager->parseDsn('mysql://cacti:c...')\n#2 /usr/share/cacti/site/plugins/npc/lib/Doctrine/Manager.php(176): Doctrine_Manager->openConnection('mysql://cacti:c...', NULL)\n#3 /usr/share/cacti/site/plugins/npc/config.php(17): Doctrine_Manager::connection('mysql://cacti:c...')\n#4 /usr/share/cacti/site/plugins/npc/npc.php(23): include('/usr/share/cact...')\n#5 {main}\n thrown in /usr/share/cacti/site/plugins/npc/lib/Doctrine/Manager.php on line 335, referer: http://127.0.0.1/cacti/plugins.php

Im using
cacti version = 0.8.7g
NPC version = 2.0.4
nagios version = 3.2.3

I havent installed NDOutils but I don't think this is the cause.

So basically when I click the npc tab and the top in firefox I get a white screen and under other browsers it gives page can't be displayed.

Any help is appreciated!


Figured it out. FYI if anyone else has this problem....
Edit your /plugins/npc/config.php file and replace

$dsn = "$database_type://$database_username:$database_password@$database_hostname:$database_port/$database_default";

with:

$dsn = "$database_type://'$database_username':'$database_password'@'$database_hostname':$database_port/$database_default";

Hello! Can you help me, I installed NPC but it didn`t work. A don`t know what the problem is..
Please help me.
P.S. Sorry for my english, I`m from Ukraine...

I think it may be to do with the version of PHP you have running?

[DWAyotte]

It might also be due to the package he downloaded.

Try this one instead: http://www.mediafire.com/?iefyesb24ppsbwl

[spikeathome]

Ah! Indeed, thats much better, I had the same issue, it worked fine, just didnt get the images but I put it down to my php version, thanks for that

[DWAyotte]

No problem at all, it was a painful issue for me to figure out, so you may have noticed me replying to just about every NPC topic on the forum in the last day or so about using the right package. I just want to help others avoid the pain I went through haha.

Hi,

I have some problem with configuration dashboard on NPC 2.04. When i want resize portlet configuration i see empty screen and just to options to do: save and cancel (look on attachment file). I tried to change configuration with firefox, chrome, ie on various Os and nothig :/
Somebody knows how to solve this problem?

Thanks 4 youreply

[ddrach]

I see that all process are working properly but that in fact the cacti database is returning null even though there is data populated in the database. I do return data directly from the event viewer as nagios and cacti are on the same box. I did look back in the thread and tried a few of the things but they had no effect so I put them back to their respective defaults.

I appreciate any input toward this resolution.
