6. What is OpenNMS?
7. World’s first enterprise grade network management platform developed under the open source model. - Tarus Balog What is OpenNMS?
8. https:/ /github.com/opennms C SourceForge registered 2000
9. Debian 8 Ubuntu 14.04 LTS CentOS 7.1 / RHEL 7 Windows 2012 Server
10. Debian 8 Ubuntu 14.04 LTS CentOS 7.1 / RHEL 7 Windows 2012 Server
11. Subscription commercial
 support Like Fedora Like RHEL release early
 release often community
 support
13. Versions foundation base for Meridian (14.0.3) stable 16.0.3 testing 16.0.4 unstable release candidate 17 snapshot 18.0.0-SNAPSHOT
14. Some numbers Contributors 52 Commits > 30.000 Accepted Pull Requests > 400 SNMP MIB Objects for data collection > 2000 Trap MIBS > 200 Downloads ~ 6000 / month
15. GitHub Commits
16. History • First held in 2005 with 7 participants(4 of which are still active community members) • DevJam has been held 8 times over the last 9 years(2005-2013 except 2009) • 6 times it has been located at the University of Minnesota – Twin Cites Campus DevJam
