The ENPAQ Enterprise Manager software is based on open source software and has a client-server based architecture. The server runs on a Linux-based ENPAQ Enterprise Manager. The clients, running on all the remote hosts that need to be monitored, can use any hardware or operating system.

There are three parts to the software:

• Plug-ins: These are small programs or scripts configurable by the user. They check a service on a network element and return the collected result to the server.
• Scheduler: This component of the server software checks the start and stop time of any data collection. The scheduler also checks the plug-ins at a regular interval.
• GUI: This component displays the configuration options as well as the collected data in various report formats in web pages.

The server uses the scheduler to poll the plug-in software at a periodic interval. The plug-in software in the server, checks to see if the device or service is up and running. The device or service has a name, IP address, a list of checks that should be run on it and a maximum number of checks that should be performed before concluding that a problem exists. After collecting the relevant data, the plug-in software, sends the information to the server. A plug-in can return metric status like OK(0), WARNING(1) or CRITICAL(2). It can also return performance data in the format: "var1=value1 var2=value2, etc."  In the second option the data is stored in the server database as historical data and can be later displayed by the server software in an online report format via the web GUI.  The server can have a hierarchy of hosts and services defined. Each of them can define what all checks should be run on them and what actions should be taken after the check fails, by selecting the appropriate parameters from the user configuration.
