1. Network Management using OPENNMS System

2. It was designed to manage:
OpenNMS (Open Network Management System) is the first enterprise- grade network management platform developed under the open source model.
It was designed to manage:
tens of thousands of devices from a single server
as well as manage unlimited devices using a cluster of servers.
It is developed and supported by a community of user and developers as well as by the The OpenNMS Group, offering commercial services, training and support.

3. goal
The goal is for OpenNMS to be a truly distributed, scalable management application platform for all aspects of the FCAPS network management model while remaining 100% free and open source.
Currently the focus is on Fault and Performance Management.

4. Platform Support and Requirements
OpenNMS includes a discovery engine to automatically configure and manage network devices without operator intervention.
It is written in Java and is published under the GNU General Public License.
Platform supported : Linux ,Fermi Linux, Cent OS, RHEL 3 & 4, Debian Sarge, SuSE, Red Hat Linux, Mandrake, Solaris, Mac OS( panther).
OpenNMS is listed as one of the top 400 projects on Sourceforge and won the Best Systems Management Tool at LinuxWorld Expo in August of 2005.

5. Features Event Management and Notifications:
OpenNMS is based around a "publish and subscribe" message bus.
Processes within the software can publish events, and other processes can subscribe to them.
In addition, OpenNMS can receive events in the form of SNMP Traps, Syslog messages etc.
Events can be configured to generate alarms.
While events represent a history of information from the network, alarms can be used to create correlation workflow.

6. Service polling:
OpenNMS provides real-time event-driven systems.
Events are typically from SNMP traps, but can come from other sources such as syslog.
There is no polling interval as such in these systems. If a node goes down, an SNMP trap is generated by the switch immediately.
True real-time network monitoring OpenNMS has the ability to poll the following services (ICMP ,NotesHTTP, DominoHTTP ,Citrix ,LDAP ,SNMP ,SNMPv2 ,and many more…. )

7. Discovery and Provisioning
OpenNMS contains an advanced provisioning system for adding devices to the management system.
This process can occur automatically by submitting a list or range of IP addresses to the system (both IPv4 and IPv6).
Devices can also be expressly added to the system, as well as a combination of the two.
The provisioning process is asynchronous for scalability, and has been shown to provision networks of more than 50,000 discrete devices as well as networks of single devices with over 200,000 virtual interfaces, each.

8. Service Monitoring
The service assurance features of OpenNMS allow for the availability of network-based services to be determined.
The types of monitors span from the very simple (ICMP pings, TCP port checks) to the complex (Page Sequence Monitoring,[12] Mail Transport Monitor[13]).
Outage information is stored in the database and can be used to generate availability reports.

9. Data Collection
Performance data collection exists in OpenNMS for a number of network protocols including SNMP, HTTP, JMX, WMI, XMP, XML, NSClient, and JDBC.
Data can be collected, stored, graphed as well as checked against thresholds.
The process is highly scalable, and one instance of OpenNMS is collecting 1.2 million data points via SNMP every five minutes

10. Architecture

11. There are actually two main applications in the OpenNMS product:
the application itself and the web-based User Interface (webUI).
The webUI is implemented via Tomcat(is an open-source web server), and it is possible for Tomcat to be running and the OpenNMS application to be stopped and vice versa.
