vCMDB is an open source tool for computer equipment and network management , configuration and customer relationship. The VCMDB data base (Configuration Management DataBase) does not depend on a particular software and has been configured to control various internal tools and softwares. The vCMDB role is to represent an information data base with a single entry point for information request and outputs to other internal softwares (eg CRM, Nagios, Bacula, supervision, Cisco equipment configuration). The software was developed in PHP / mySQL and it includes a search engine that allows you to quickly find several types of data (text, serial numbers, phone numbers and other).


Introduction and Philosophy

vCMDB (Vincent Configuration Management DataBase) was originally developed for Rezopole in order to centralize in a single database the entire information system:

  • Equipment (servers, routers)
  • Sites and racks
  • Optical drawers and fiber numbers
  • IP addresses and VLAN

We could have started from an existing software : GLPI, OCS, Racktables, Centreon ... These are great tools, but often very typical IT and not able to store all the information you want (try putting 12 power sources to your server to see if it works ^ ^). It therefore need patches / plugins / synchros to interconnect everything you use. And we bet bet your data is duplicated in several places.

We rather use a typical Merise base (or UML) that we customize in order to accurately represents your information system. Each will have its own, but you can create the connections you want. vCMDB will allow you to be able to extract the data to your favorite applications:

  • Nagios
  • MRTG
  • Cacti
  • dhcpd
  • named
  • bacula
  • dokuwiki
  • vtiger

And when you will make the choice (voluntary or not) to change one of these tools, your database will not change, you will only need to update your exports.


Initially we wanted from to create a generic tool that can be used by both hosts/ISP, but also by any company that wants to better organize its data. Goodbye excel files and post its :)


After an extensive search of the various existing open source CMDBs, the best solution found in 2012 was onecmdb. The framework java is very VERY slow, so we decided to redevelop from scratch in PHP/MySQL.

vCMDB is distributed as Open Sourc,e under the Affero GPL licence.


Elements requiered

In order to run vCMDB, you need :

  • MySQL (InnoDB)
  • libapache2-mod-php5
  • php-fpdf
  • php5




File tree view



For each object, we want to be able to execute an action when the object is added/modified/deleted.

To create a trigger,you need to creat a file:<br> triggers/<object>.php

And to create a function:
function trigger_<object>($action, $prepost, $id, $fields=null){
global $vcmdb;
global $global_url;

We do not charge any triggers when starting up to not overload the code and the loading.<br>

The prepost variable can either be:

*”pre”  if you want to run a command before the action *”post” if you want to run a command after the action


When an object such car is displayed, the edit page is lookingto see if there is a page:


If the page exists, it includes it in the PHP code. We can therefore perform various operations on the object or the generation of configuration. All configuration variables are already loaded:

$vcmdb Accès à la classe de gestion de la base de données
$data[] L'objet
$data_references[] Les liaisons 1 vers 1
$data_relations[] Les liaisons 1 vers n




The scripts can be found in 3 different locations:

the data import scripts to vCMDB will be placed in imports
the data or pattern generation export scripts generation will be placed in exports
the scripts directory is for scheduled tasks or for scripts that you run manually with the PHP binary

MySQL data base

The tool is intended to be as generic as possible and stores this data in a database.

So that one can possibly easily question the database, we created a table for each object. We use the Merise 2 model. <br>

Warning: It is forbidden to create a table called ANY.

The '_' character and space can be used in object names (you should avoid accents and apostrophes). Each object is identified by a table in the database:

objet1_objet2(_description) correspond à une jointure 1 vers 1 entre 2 objets

Here is how the keys are described in the database:

id ⇒ primary key
id_table(_description) ⇒ foreign key to a particular table
id_any_description ⇒ foreign key to any object stored as table/id

When you create an object, the following fields are automatically created:
Attribut    Description
id    primary key
created     date / time of creation
lastModified     date / time of modification
Table systems
vcmdb-action     The list of possible actions on an object (used for managing permissions)
vcmdb-history     Object history
vcmdb-language     Languages managment (TO DO)
vcmdb-menu     Top menu
vcmdb-menu-url     Les sous menus

File storage

We can attach to each object one or several files. One can thus attach:

hardware quotes
purchase orders signed to a company

Storage is currently being done on the web server, but the software has been design tobe able to export storage by FTP for example.

To start your own first script, it is important to throughly read the contents of classes
Search an objet

Here is a simple example to get you started, we display all object account

foreach($vcmdb->search("account") as $account) {
echo $account['name'];

Easy right ?
You can also search with conditions:

foreach($vcmdb->search("societe",Array('name'),'name',Array("name like '%a%'")) as $account) {
echo $account['name'];

Retrieve an object information

$societe = $vcmdb->get("account",1);
echo $account['name'];

Collect all related objects

This allows you to retrieve all objects that refer to the inital object <br>

$array = $vcmdb->get_related_objects("account",1);

Workshop AXIS

on Monday, 02 June 2014 Posted in article

Rezopole contributes to Internet and IXP development projects all across Africa. Throughout a partnership with the ISOC, Rezopole team member, CEO Samuel Triolet, has conducted several technical trainings, workshops and post training sessions in Burkina Faso, Burundi, Tchad, Benin, Algeria, The Ivory Cost, Senegal and Morocco, for local Telecom operators.


These trainings are part of the AXIS project (African Internet Exchange System), lead by the African Union and the ISOC, which aims to support the development of national and regional Internet exchange points in Africa and to keep African traffic local.

Workshop Dark Fiber Contracts

on Monday, 02 June 2014 Posted in article

Rezopole offers its members a legal and technical training on public and private contracts for the provision of dark fiber (FON) in partnership with Mr. Dimitri Meunier, lawyer from LexCase and engineers from SOGETI.

From a pragmatic approach to the study of practical cases and feedbacks, you will get the technical and legal knowledge needed to master the challenges of these contracts, their negotiation and drafting, and their implementation.



Presentation of the technical issues of a dark fibet network:

- The PIN (Public Initiative Networks) case
- The private network case
- Feedback from practical cases
- Regulatory and contractual aspects



  • Reminder of various acquisition scenarios for dark fiber network (private, public, commercial) --> Sogeti
  • Technical issues for the buyer --> Sogeti
  • Contracts definition (I.R.U., Rental, Purchase Construction) --> LexCase
  • The provision, delivery and checking operations, what responsibilities for the contractor? --> LexCase / Sogeti
  • The value of annexed contracts to the holder offer (Terms and Conditions,IRU, Rental...) as part of a public purchasing --> LexCase



To attend the technical and legal training on dark fiber contracts, simply request a quote to Rezopole.

And if you want to test this project or do a POC (Proof Of Concept), contact Rezopole!


We will find you a partner who can provide you the services that you need and advises you throughout your project.
Since 2008, Rezopole has managed several YTest projects. In 2009, during the interconnected1 events,YTest received the “Label des territoires innovants2”.



1 The interconnected is an independent and non-profit organization kown in French as “ Les interconnectés, Le réseau des territoires innovants”.

2 The innovation label  offers to selected projects a recognation and a national prospective.
