  • The World's First Enterprise-Grade Open Source Network Management
    The World’s First Enterprise-grade Open Source Network Management Platform OpenNMS is the world’s first enterprise-grade Event Management and Notifications network management application developed under the open-source model. It is a free OpenNMS is event driven, and the system has software alternative to commercial products such the ability to generate internal events, such as a as Hewlett-Packard’s OpenView, IBM’s Netcool loss of a service, as well as to receive external and Tivoli, and CA Unicenter. events, such as SNMP Traps. Each event can be fed into a robust notification system that can Because OpenNMS is open source software, there send e-mails, pages, text messages, pop-ups are no software license costs. Since the software and even instant messages via XMPP (Jabber). code can be freely modified, OpenNMS can also Notices can be acknowledged, automatically be changed to fit the way the organization works, resolved and escalated. instead of having to change processes and procedures to fit the software. OpenNMS was designed from Day One to be able to monitor tens of thousands of interfaces. The ultimate goal for the software is to become the de facto network management platform. OpenNMS is focused on four main areas: • Automated Discovery • Event Management and Notifications • Service Level Monitoring • Performance Data Collection In addition, OpenNMS includes an event translator that can take an event and turn it Automated Discovery into another event. Fields in the original event It would be very difcult to configure by hand can then be parsed and used to access external thousands of devices, thus OpenNMS was databases (such as a customer or inventory designed to automate the process of network system) and a new enriched event created.

  • SNMP (Polling and Traps, Mibs, DELL Openmanage)
    OpenNMS Daniel Traynor, GRIDPP, QMUL HEPSYSMAN June 2014, RAL OpenNMS Monitoring Overview SNMP (polling and traps, mibs, DELL openmanage) (r)syslog OpenNMS Basics, Installation, automated and directed discovery. Examples Monitoring Choice Do a search for network monitoring and you can find lots.. http://en.wikipedia.org/wiki/Comparison_of_network_monitoring_systems e.g. cacti, ganglia, nagios, but lots of others …. Have setup and used Zenoss in the past, needed to upgrade hardware, found that new version of Zenoss required lots of extra packages not in SL6. Chose OpenNMS after recommendation from FOSSUK2013. Also used in Physics at QMUL. Requirements Open source. Network service checks (e.g. ssh, DNS, ntp, snmp, https:1311). SNMP polling and SNMP trap receiver (does not use agents on clients). syslog monitoring. Automated [directed] discovery. Performance measurements. SNMP On SL install net-snmp also snmpv3 for secure monitoring useful to install net-snmp-utils for (used by QMUL physics), gridpp testing with snmpwalk / snmpget. use v2 on private network. community name set to random string ro for reading not writing set IP address to limit access monitor disk space in usefull units set values for standard variables override default values setup dell openmanage to send snmp traps to our monitoring box make extra information available (fans, tempt,…) SNMP MIB Management information bases (MIBs) define the structure of the data of a system via object identifiers (OID). An OID identifies a variable that can be read or set via SNMP. MIBs exits for e.g. linux, switches (HP, Force10,…) also enterprise versions, e.g. DELL MIB provides fans speeds, server temperatures etc… OpenNMS already knows about a lot of these MIBS.
