<title>What is Pandora FMS?</title>
<para>
Pandora FMS is a monitoring tool that allows a system administrator
to visually analise the status and efficiency of Operating
Systems, Servers, Applications and Hardware Systems - such as
firewalls, proxies, databases, Web servers, tunnelling servers,
routers, switches, processes, services, remote access servers
and so on. All integrated into an open and distributed
architecture.
</para>
<para>
Pandora can be implemented on top of any operating system, with specific
agents for each platform. Pandora can also monitor any TCP/IP
hardware system, as load balancers, routers, switches, printers
and so on.
</para>

<para>Pandora architecture is formed of four main components:</para>
<para>
<emphasis>- Web Console:</emphasis> Pandora's user
interface. The user controls and operates the system with
it. Several Web consoles can be implemented in a single system.
The Web console is written in PHP, and it lies on top of a database and a
Web server. It is compatible with any platforms - GNU/Linux,
Solaris, Win2000, AIX, etc. Although, the official supported
platform is GNU/Linux.
</para>
<para>
The console permits the user to control the status of the
agents, view statistical information, generate graphs and data
tables, keep a system incident control. Moreover, it will be able
to generate reports and change the alerts, agents, and user profile
settings.
</para>
<para>
<emphasis>- Core Server:</emphasis> Pandora Core server is the
receptor of the data packages and generates the alerts - it is
the brain of the system. Several servers can work alongside for
larger systems. It has been developed in Perl and works over
any platform, although, the official platform is GNU/Linux.
</para>
<para>
The core server accesses Pandora database, which is shared with
the Web server, and stores the processed data packages. The
server is executed under the name of "Demon", and processes
the packages stored in its file system. The data is generated
by the system agents. Despite the server's low system resources
comsumption and simple installation and operation, the core
server is the most critical element of the system. The core
server receives and processes the produced data, and fires the
alerts and the events.
</para>
<para>
<emphasis>- Central Database:</emphasis> At the moment the
system only supports MySQL. The central database keeps all the
information Pandora needs to work - agent data, settings, user
information, incidents, system settings, etc. The system can use
a MySQL cluster to store the information, or a High
Availability (HA) solution for larger sytems.
</para>
<para>
This database can work with any of the platform officially
supported by MySQL. Pandora can be implemented with MySQL
versions 3.0 and 4.0, although the latest is recommended.
</para>
<para>
<emphasis>- Pandora Agents:</emphasis> They collect all the
system's data. They are executed in each local system, although
they can also collect remote information by intalling monitoring
sytems for the agent in several different machines - called
satellite agents.
</para>
<para>
They have been developed to work under a specific platform,
making use of the specific tools of the used language:
VBSCript/Windows Scripting for Microsoft platforms (Win2000,
WinXP and Win2003) and ShellScripting for Unix - which includes
GNU/Linux, Solaris, AIX, HP-UX and BSD, as well as the Nokia's
IPSO. Pandora agents can be developed in virtually any language,
given its simple API and being open source.
</para>

<title>Pandora Administration</title>
<para>
The web console is the tool used to administrate
Pandora. It is written in PHP and doesn't need any
third party software to work, neither FLASH, JAVA,
nor ActiveX plug-ins. The Web console can be run
over any web browser supporting HTML and CSS (IE5+
or Mozilla 4+).
</para>
