Repo Name

Description

In current legacy network, NMS (Network Management Systems) is a viable approach to provide a centralized system that monitors and controls remote/managed devices located throughout the network, using for examplle SNMP (the basic protocol). Of-course there are others protocol like TL1, TMF/Corba that are also being leveraged to monitor the managed network.

With the advent of Software Defined Networks, the basic need arises to monitor the network (Controller, deployed features, network etc.). As a first step, on priority the need arises to expose the SDN Controller' (OpenDaylight) health/statistics to existing legacy NMS applications. With SDN networks yet to provide inter-working for monitoring/management functionality, the need arises to at least enable the NMS operators to get access to health/diagnostics information from/of SDN Controller.

Scope

Cardinal (OpenDaylight Monitoring as a Service) proposes a solution in OpenDaylight that extends the following for a remote NMS:

OpenDaylight MIB (Management Information Base) defined in OID experimental
Enable ODL diagnostics to be exposed across SNMP for remote NMS
Integrate with OpenDaylight TSDR and Centinel for monitoring data and analytics
Extend ODL diagnostics across northbound for autonomous notifications (SNMP Traps)

Cardinal feature (Karaf support)

Run snmpd/snmptrapd daemon in background once the Cardinal feature is turned on
Supported SNMP commands - snmpwalk, snmpget, snmptranslate, snmpgetnext
SNMP Autonomous events (INFO & Traps) will be supported

Cardinal Core ODL Data

Introduce SNMP OID for OpenDaylight monitoring/inter-working to remote/legacy NMS
Support ODL diagnostics – ex: ODL health (CPU, Memory usage, up time etc.)
Support autonomous notifications - ODL SNMP Traps and INFO messages
Interacts with Karaf using SSH or REST APIs (if available)
Interacts with MD-SAL to store relevant data into datastore

Cardinal REST APIs

Support REST GET equivalent to SNMP GET requests - to enable SDN Applications to retrieve ODL diagnostics
POST to start/stop daemon

OpenDaylight SNMP MIB (experimental OID)

SNMP OID defining OpenDaylight diagnostics data
SNMP OID defining OpenDaylight autonomous notifications (Traps, INFO)

OpenDaylight diagnostics data (SNMP)

Support SNMP (snmp* requests) for exposing OpenDaylight diagnostics data
Support SNMP (INFO, TRAPS) autonomous notifications from OpenDaylight
Support REST API for OpenDaylight north-bound to retrieve equivalent to SNMP data-set from OpenDaylight north-bound
Integrate with TSDR and Centinel for OpenDaylight / SDN network data (proposed for Cardinal - Carbon)

X – Data collector /Listener

Listens on data according to the rules (proposed for Cardinal - Carbon)
Interacts with MD-SAL to put listener on SB data (proposed for Cardinal - Carbon)
Provide APIs to receive notifications (proposed for Cardinal - Carbon)
Persistence feature like TSDR can send notification alerts (proposed for Cardinal - Carbon)
