This stand-alone application collects information from a single OCS Inventory NG server in order to populate the iTop CMDB with the collected Servers, PCs and Virtual machines. The collector uses the iTop data synchronization engine to synchronize the information between OCS Inventory and iTop.

An additional (and optional) extension is available to display the content of the OCS Inventory pages directly inside iTop, for each synchronized object (Server, PC or Virtual Machine):

• Automated inventory of Brand, Model, OS Family, OS Version, Physical Server, PC and Virtual Machine from OCS Inventory server
• Automated inventory of Network Interfaces
• The collector can reside on any system with web access to iTop and mysql access to the OCS Inventory server
• Automatic creation and update of the Synchronization Data Sources in iTop.
• An optional small extension is available to display an extra tab “OCS Inventory” on synchronized PCs, Servers and VirtualMachines. This tab displays the OCS page for the device (using an IFRAME).

• The collector does not retrieve installed software information
• The collector is not normalizing Model, OS Family and OS Version
• The collector synchronizes only PCs and Servers which have a valid serial number in OCS
• The current version is not compatible with TeemIP
• If your iTop is accessed using HTTPS, then the same must be true for OCS Inventory otherwise the inline frame of OCS Inventory inside iTop will not display because of browsers's security restrictions.
• There is no single sign-on between iTop and OCS, so you'll have to login to OCS when displaying the OCS tab.

• PHP Version 5.3.0
• An access to the OCS Inventory NG mysql database
• An access to the iTop web services (REST + synchro_import.php and synchro_exec.php). Note: starting with iTop 2.5.0, the user must have the profile REST Services User in iTop.

• Go to the extensions store on iTop Hub
• Click on the cart icon to make the acquisition of the extension and follow the on-screen instructions to deploy it on your iTop instance

• unzip the file “itop-ocsng.zip” into the iTop extensions folder
• make sure that the web server process has enough rights to read the copied files
• Launch iTop setup
• Select the OCS Inventory Integration extension, when prompted

• Edit the iTop configuration file to specify the URL to access the OCS web server:

	'itop-ocsng' => array (
		'ocsng_url' => 'http://localhost/ocsreports/',
	),

• Expand the content of the zip archive “ocsng-data-collector” in a folder on the machine that will run the collector application. This machine must have an SQL access to the OCS NG database and a web access to the iTop server.
• create the file conf/params.local.xml to suit your installation, supplying the appropriate credentials to connect to OCS NG and iTop.

By default this file should contains the values used to connect to iTop server and OCS NG server:

<parameters>
  <itop_url>http://localhost/</itop_url>
  <itop_login>admin</itop_login>
  <itop_password>admin</itop_password>
  <contact_to_notify>john.doe@demo.com</contact_to_notify>
  <synchro_user>admin</synchro_user>
  <sql_host>localhost</sql_host>
  <sql_database>ocsweb;charset=UTF8</sql_database>
  <sql_login>root</sql_login>
  <sql_password>root</sql_password>
</parameters>

By default the data collection configuration is defined in the file collectors/params.distrib.xml. Do not modify this file! If you need to adapt the configuration, create a file named params.local.xml in the conf directory and copy/paste the needed definitions into it (the structure of both XMl files is the same). This configuration defines which SQL queries have to be executed on the OCS NG server to retrieve the data and synchronize with iTop.

• For each class of object to import into iTop (PC, Server, VM, Brand, Model, OSVersion OSFamily), a Synchro Data Source is created by the collector application.
• Each collector is associated with an SQL query (via the parameter <name_of_the_collector>_query).
• This query must return column where aliases (i.e. “name” of the columns) correspond to the expected fields for the corresponding Synchro Data Source.
• These queries can be adapted to suit your needs (for example to better differentiate PCs and Servers or to change/set some default values for some columns)
• Since the synchronization of PCs, Servers and Virtual Machines all rely on their own SQL query, it is important to make sure that the results of these 3 queries do no overlap. Otherwise the same “system” will be imported several times in itop (for example as both a PC and a Server).

These queries can be redefined in the file conf/params.local.xml in order to take into account your specific needs (For instance change de status of created Server, PC, Virtual Machine, as well as de default organisation). By default, only VMWare virtual machines are created. The Virtualmachine query has to be adapted if you want to handle other type of VMs

To launch the data collection and synchronization with iTop, run the following command (from the root directory where the data collector application is installed):

php exec.php

The following (optional) command line options are available:

The execution of the command line will:

1. Connect to iTop to create the Synchronization Data Sources (or check their definition if they already exist, updating them if needed)
2. Connect to OCS NG to collect the information about the Servers, PC, Virtual Machines
3. Upload the collected data into iTop (this is the configuration parameter <name_of_the_collector>_query
4. Synchronize the collected data with the existing iTop CIs.

Once you've run the data collector interactively, the next step is to schedule its execution so that the collection and import occurs automatically at regular intervals.

The data collector does not provide any specific scheduling mechanism, but the simple command line php exec.php can be scheduled with either cron (on Linux systems) or using the Task Scheduler on Windows.
