Functionality

Network Manager (full version) makes possible:

• auto discovering of devices included in monitored networks and adding them to the database of managed devices;
• visualization of monitored network topologies according to data gathered from managed devices through SNMP protocol;
• monitored device states visualization (states of network interfaces, BGP sessions);
• visualization of responses of monitored devices for ICMP ECHO packets sent by the management station (similary as ping command);
• creating objects that represent service, node etc., which state depends on states of other objects and services stored in the database;
• running directly from presented topology maps the most suitable control panels for selected devices and other graphic applications of David system;
• designing graphic interfaces to control network devices that supply SNMP protocol; appearance of each interface and its functionality depend on an end-user invention (every control panel is written as a separate file);
• real-time monitoring (considering speed of computer networks and polling interval) of devices work parameters and controlling its work, through generated application - control interface to a particular device;
• visualization of network device work parameters through a generated application - interface to a particular device;
• collecting current parameters of monitored devices work using SNMP protocol;
• presenting collected data as graphs available in Web site;
• sending collected data, current data about parameters of monitored devices work to Operation Manager; it makes possible to detect potential problems in early phase.
• management of David system user accounts (creation and modification of user accounts);
• notifing an operator about a received message and recording its identufier and reaction time.

One of Network Manager assignments is discovering objects into managed networks, building topological maps of monitored networks and visualization of discovered device states.

The product can gather information about networks from their nodes through SNMP protocol, and next can visualise the gathered data through Web application which is a user friendly interface to the database.

An important assignment of the product is gathered current work parameters of monitored network devices using SNMP protocol. The collected data can be presented as graphs through Web browser. The collected data also are forwarded to Operation Manager.

Network Manager on the basis of its configuration files can generate applications, that are graphic interfaces controling, through the network, devices on which SNMP agents work. Usually such interfaces show parameters of device work, which are important in a given situation. Many interfaces to a particular device may exist at the same time. The panels can be easy created and modified by end-users. Main edition technique used to creation of panels, like in a different kind of graphic editors, is using a mouse as a main design tool.

Network Manager can also manage user accounts. These users are quite independent of operating system users on which David system works. Each user has a name (identifier), a number (UID), a privilege level (ULEVEL - zero means the highest level), a password and a description of his/her account (GECOS).
