HP OpenView Network Node Manager

HP OpenView Network Node Manager (NNM) is a network management solution platform for discovery, monitoring, and management of TCP/IP networks.

NNM’s SNMP-based management capabilities provide an enhanced solution for managing network and system devices using SNMP in TCP/IP network environments.

NNM provides fault, performance and configuration management for multivendor TCP/IP networks for a site, campus, or enterprise.

7/28/2016

10

How does it work?

• NNM uses several protocols to maintain communication with each managed device– SNMPv1, SNMPv2– TCP/IP, IPX– UDP– ICMP– ARP/RARP

SNMP Network Mgmt Model

Manager

A manager is an application that executes network management operations

The manager monitors and controls agent systems

SNMP agent

Resides on a managed node

An application that acts on behalf of an object

Object

Anything that will be managed

Host, router, hub, application, database

Simple Network Management Protocol

SNMP is a framework that provides facilities for managing and monitoring network resources on the Internet.

Components of SNMP:

SNMP agents

SNMP managers

Management Information Bases (MIBs)

Simple Network Management Protocol

SNMP agent is software that runs on a piece of network equipment (host, router, printer, or others) and that maintains information about its configuration and current state in a database

Information in the database is described by Management Information Bases (MIBs)

An SNMP manager is an application program that contacts an SNMP agent to query or modify the database at the agent.

SNMP protocol is the application layer protocol used by SNMP agents and managers to send and receive data.

MIBS

A MIB specifies the managed objects

MIB is a text file that describes managed objects using the syntax of ASN.1 (Abstract Syntax Notation 1)

ASN.1 is a formal language for describing data and its properties

In Linux, MIB files are in the directory /usr/share/snmp/mibs

Multiple MIB files

MIB-II (defined in RFC 1213) defines the managed objects of TCP/IP networks

7/28/2016

16

Organization of managed objects

Managed objects are organized in a tree-like hierarchy and the OIDs reflect the structure of the hierarchy.

Each OID represents a node in the tree.

The OID 1.3.6.1.2.1 (iso.org.dod.internet.mgmt.mib-2) is at the top of the hierarchy for all managed objects of the MIB-II.

Manufacturers of networking equipment can add product specific objects to the hierarchy.

Traps

Traps are messages that asynchronously sent by an agent to a manager

Traps are triggered by an event

Defined traps include:

linkDown: Even that an interface went donw

coldStart - unexpected restart (i.e., system crash)

warmStart - soft reboot

linkUp - the opposite of linkDown

(SNMP) AuthenticationFailure

SNMP Versions

Three versions are in use today:

SNMPv1 (1990)

SNMPv2c (1996)

Adds “GetBulk” function and some new types

Adds RMON (remote monitoring) capability

SNMPv3 (2002)

SNMPv3 started from SNMPv1 (and not SNMPv2c)

Addresses security

All versions are still used today

Many SNMP agents and managers support all three versions of the protocol.

Automatic Discovery and Layout

All IP and Level 2 devices on the network are automatically discovered and mapped

IPX devices are also discovered

Map is a logical representation of your network

Automatic discovery may take several hours or even overnight

Network Discovery (cont’d)

NNM discovers the following objects and put them on the default map

Internet-level submap

IP networks, gateways, routers and multihomed workstations

Network-level submaps

Bus, star and ring segments

Segment-level submaps

Hosts, gateways, routers, switches, hubs, and bridges

Node-level submaps

Network interface cards

Simplified Distribution Model for NNM

7/28/2016

27

Management Consoles

NNM gives the ability to have 15 to 25 operators simultaneously monitoring the network

Operators can share one map , or have individual maps

Individual maps create area of responsibility on the network for each operator

More efficient in large networks

HP OV NNM Event Generation

NNM processes and SNMP agents continuously watch for certain incidents to occur

When an incident occurs, an event is generated

Events are categorized based on the alarm type

Alarm types are user definable

Events are displayed with color coded severity

Severity and color codes are user definable

Event trap configuration

HP OMW

HP Operations Manager (formerly known as OpenView Operations—OVO) has evolved from a mere NNM (Network Node Manager), gathering its data via SNMP traps, to a host-and-application focused monitoring product.

OVO talks to your devices and gets all kinds of information from them without having to connect each device to a management station. Basically a software program to automatically question any or all of your devices every so often. It uses simple templates to access a database of information on the target device, like, health, workload, missing processes, missing devices and so on.

HP Operations Manager (HPOM) is a distributed client-server software solution designed to help system administrators detect, solve, and prevent problems occurring in networks, systems, and applications in any enterprise.

Technical benefits

Network Management can help achieve those goals by:

Fault and Problem Management

Reduced downtime of network systems and devices

Quick detection and correction of network problems

Performance Management

Ability to monitor data to anticipate problems

Log information for historical analysis

Business Benefits

Network Management can help achieve those goals through:

Accounting Management

Obtains statistical information on network use

Track individual resource utilization

Security Management

Protects the network and its systems from unauthorized access, use, and harm

Summary

hp OpenView NNM is a robust network management platform that can provide a graphical look into your network and provide many benefits like Fault and Problem management, Performance management, etc

Makes network management proactive instead of reactive

NNM uses SNMP to discover devices on the network and automatically manage and monitor them

NNM can play an integral role in achieving both the technical and business goals of an organization
