Pandora (Free Monitoring System)
From Wikipedia, the free encyclopedia
Pandora FMS are a Free Software set of programs, licensed under the GNU General Public License, that allows to analyze in a visual way status and performance of several parameters from different operating systems, servers, applications and hardware systems such as firewalls, proxies, databases, web servers or routess. All integrated into an open and distributed architecture.
Pandora FMS can be deployed in almost every Operating System, having an agent for every platform and can monitor hardware systems with TCP/IP stack, as load balancers, routers, switches, printers, etc.
Pandora FMS has six components: Pandora Data Server, Pandora Network Server, Pandora SNMP Console, Pandora Agents, Pandora Database and Pandora Web Management System (Web Console).

[edit] Components
[edit] Pandora Servers and SNMP Console
The servers are the recipient of bundles of information and the generator of alerts, so they are the brain of the system. We can have several servers for very big systems or a single server. They are developed in Perl and works under any platform, with the required modules. Nevertheless its best integrated platform is GNU/Linux. They also insert the gathered data into the Pandora database. It's possible to have several Pandora Servers connected to the same Database.
[edit] Pandora Web Console
It allows to manage the system and to operate with it, the user interface of Pandora. We can have several Web Consoles in the same implantation. It is developed in PHP and leans on a Data Base and a Web Server, being able to work in any platform: GNU/Linux, Solaris, Win2000, AIX and others.
[edit] Pandora Database
This is the core module of Pandora. Here resides all the information of the system. For example, all data gathered by agents, configuration defined by administrator, events, incidents, audit info, etc is stored in the database At this moment, only MySQL database is supported. More databases system support is planned to be added in the future.
[edit] Pandora Agents
They can monitor any numeric parameter, boolean states, strings or numerical incremental data and/or condition. They have a centralized architecture based on lightweight design for agents (shellscript, wsh, Perl) and light agents to collect data. They support all type of platforms (Microsoft, AIX, Solaris, GNU/Linux, IPSO, FreeBSD, SAP, etc) because the agents are completely free software, and they communicate using SSH, FTP, NFS or other good way, using an XML container to transport data.
