OpenNMS is an enterprise grade network monitoring platform developed under the Open Source model. It consists of a community supported open-source project as well as a commercial services, training and support organization.
OpenNMS aims to be a truly distributed, scalable platform for all aspects of the Fault, Configuration, Accounting, Performance, Security (FCAPS) network management model, and to make this platform available to both open source and commercial applications.
It has a configurable, event-driven messaging subsystem that allows you to plug-in event streams from other sources, such as vulnerability information from Nessus, tailed log files, and /proc-based monitors.
OpenNMS has a wide variety of monitors available.
- Service Polling – determining service availability.
- Data Collection – collecting, storing and reporting on network information.
- Event and Notification Management – receiving events, both internal and external.
- Thresholding – evaluating polled latency data or collected performance data against configurable thresholds, creating events when these are exceeded or rearmed.
- Alarms and automations – reducing events according to a reduction key and scripting automated actions centered around alarms.
- Notifications – sending notices regarding noteworthy events via e-mail, XMPP, or other means.
