Nagios Plugin for Cacti 2.0.0b (build 166) released

[divagater]

NPC-2.0.0b (build 166) is now available.

View the quick start guide for installation instructions.

Build 166 notes:
* This beta release of NPC fixes a few minor bugs.
* Setting config_output_options=2 (or 3) in ndomod.cfg is now a requirement. This corrects some instances of no data or duplicate data.
* All grids were updated to fit the bottom bar to the bottom of the browser.
* All grids now have an option for configuring the number of rows displayed.
* All grids now have the option for configuring the refresh rate.
* Portlet rows/refresh is adjusted by clicking the configuration icon in top right corner of the portlet.
* Like all other aspects of the UI the rows and refresh configuration is saved server side on a per user basis.

Build 151 notes:
Besides a few bug fixes this release takes advantage of many of the plugin management features found in the plugin architecture 2.x. including install/uninstall options as well as enable/disable option.
Uninstall removes all database traces of NPC.

NOTE: NPC now has to be installed via the plugin management section even if you are upgrading from a previous release. If you have an entry for NPC in global.php it can be removed.

----------------------------

I setup a community Trac site to host the NPC project. The NPC source as well as install guide, screen shots, etc. can be found there.

With the exception of some installation notes documentation is very slim. Here are a few tips to get you started:

* Most lists including services or hosts can be double clicked to open additional detail screens.

* Most lists including services or hosts can be right clicked to popup a context menu used to issue service or host commands.

* If a graph is mapped to a service or host, a graph icon will be displayed in the hosts and services screens. A single left click of this icon will popup the graph.

* Most green check marks (started/enabled) or most red X (stopped/disabled) can be double clicked to toggle the option (requires that remote commands are enabled.)

* Most grid columns can be re-ordered via drag and drop.

* Most grid columns can be hidden and currently hidden columns can be viewed by clicking a down arrow to the right of the column heading.

* Dashboard portlets can be closed or minimized. Closed portlets can be made visible again by clicking the Portlets button on the far right of the toolbar on the Dashboard tab and then select which portlets you want displayed.

* All changes to the interface (portlets, column order, etc.) are saved server side on a per user basis. Customize the UI your way and it is available anywhere you login.

* Importing Nagios hosts is done from the N2C link on the left side tree menu. Before starting an import you need to click in the template field to the right of the hostgroup you are importing. Doing so will expose a select box for assigning a host template.

Bugs/support

The interface currently has some quirks that I am aware of. Dragging a portlet will sometimes move several portlets at once. When this happens just reload the NPC page and the portlet order should be correct.

Grids will sometimes fail to render or display fully. Closing and re-opening the problem tab usually resolves that. When viewing host/service detail screens, allow all the data to load before clicking through the tabs.

For all other issues post your problem here, or if you are inclined open a ticket on the NPC Trac site. This is an alpha release so I fully expect issues and I need your help to find them

Cheers,
Billy

Hi,

I have installed successfully the plugin, ndo2db is populaiting the tables with data so thats working correctly.

However when i select the "NPC" tab, no data or what so ever is displayed.

Hi aleto. When you click the NPC tab all you see for instance is a big white background without any part of the interface being drawn? If that is the case either php is dying with a fatal error or the javascript is not loading.

Do me a favor and tail your apache error logs then click the tab again. Look for a log entry with "PHP Fatal error" in it.

If you are on an rpm based system get me the output of
rpm -qa | grep php

NPC requires PDO which I thought was included in PHP 5.2 however I just noticed that the php-pdo module may need to be installed seperatley.

Also, let me know what web browser you are using. I have tested in firefox 2.x and IE 7

I think I'm missing something.. how does the configuration information get populated in the database? I see various npc_tables, but they are all empty. ndo2db is running. Clicking the N2C link brings up an empty list. There doesn't seem to be any way to add any of the hosts from my Nagios setup.

This looks fantastic if I can get it to work

Thanks

Hello Good job thanks !

So I try this. And I got this issue

The installation of the plugin into cacti was good I got the tab and interface is good...

But when I compile ndo and tell nagios to use it, it does not work. Nagios won't start.

First of all I had a problem with php-json

[root@manage var]# rpmbuild --rebuild /home/xxxx/php-json-4.3.2_1.2.1-1.aurore.src.rpm
Installation de /home/xxxx/php-json-4.3.2_1.2.1-1.aurore.src.rpm
erreur: échec du déballage de l'archive dans fichier /usr/src/redhat/SOURCES/php-json-ext-1.2.1.tar.bz2;47ecc86b: cpio: read
erreur: /home/xxxx/php-json-4.3.2_1.2.1-1.aurore.src.rpm ne peut être installé


I have this in nagios.log

ndomod seems to be launched

[1206699130] Nagios 3.0 starting... (PID=4381)

So nagios do not run and I don't see any errors


In my nagios.cfg:

event_broker_options=-1

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg

process_performance_data=1


AND

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Total Warnings: 0
Total Errors: 0

I'm using fedora core 8, nagios3, cacti 0.8.7b, php5.2.4-3, mysql 5.0.45-4

Any idea... I am trying to look at the problem with json...

thx

[divagater]

json is included in PHP 5.2 and above so don't install the RPM.

[divagater]

Sorry for that short answer above but I wanted you to get that message right away

So Nagios "appears" to start but the actual process is just gone? Or is the nagios process there but its not doing anything?

[miky_willis]

OK great for json I found the answer juste after my message...

For nagios it seems to start but the process is not there.

[divagater]

By default nagios does not have debug enabled. In nagios.cfg find/set the following parameter:

debug_level=1

Make note of where it writes the debug log:

debug_file=/usr/local/nagios/var/nagios.debug

Additionaly you could crank up the verbosity from 1 to 2

debug_verbosity=1

I suspect that the ndomod.o is crashing Nagios. To test that just comment out the line that loads the module:

broker_module=/usr/local/nagios/bin/ndomod.o config_file=/usr/local/nagios/etc/ndomod.cfg

Also be sure that the ndomod.o was copied from ndomod-3x.o is the ndoutils source. Check the file size and verify they are the same. Accidently using the 2x version of ndomod would probably kill Nagios.

[miky_willis]

Thanks for rapid answer

When I comment out the broker nagios starts great

with debug level -1 (everything) I got this output when I do a restart

ndomod.o in /usr/local/nagios/bin/ really is the ndomod-3x.o

I miss somtehing but I don't know what...

[divagater]

[miky_willis]

perhaps I miss something with ndomod config...

in ndo2db.cfg or in ndomod.cfg

Please tell me if there is something wrong there

[divagater]

Thanks for posting your configs. Still working on getting a matching env setup but in the mean time I see one thing wrong and have a suggestion for trying something different.

1st, in ndo2db.cfg db_prefix has to be set like:

db_prefix=npc_

You have it currently as nagios_.

Next, I notice that you are using unix socket for the communication between ndo2db daemon and ndo module. This is the default setting however I recall having an issue with that as well. Try doing the following for me and see if it helps:

In ndomod.cfg set:

output_type=tcpsocket
output=127.0.0.1
tcp_port=5668

In ndo2db.cfg set:

socket_type=tcp
tcp_port=5668

This causes the ndomod.o module to post events to port 5668 on localhost and for ndo2db daemon to listen on port 5668 for events passed from ndomod.o.
