A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Product Overview

NNMi helps you monitor large-scale physical and virtual networks by providing you with a unified environment to view network fault, availability, and performance and proactively address problems in your network infrastructure.

NNMi uses a central server-based monitoring framework. After you install and configure NNMi on a dedicated server, also known as the NNMi management server, it begins to discover the network by gathering information about the devices connected to the network and the network topology. After completing network discovery, NNMi uses a polling mechanism to periodically collect data from the discovered network devices, which are also known as the managed nodes.

NNMi largely relies on Simple Network Management Protocol (SNMP) agents on network devices while collecting health status of each device. The Management Information Base (MIB) on each network device provides NNMi with a rich set of details on the health and availability of the device. By running periodic polls, NNMi proactively and continuously collects the data that indicates the health of the managed nodes.

Overview of NNMi Smart Plug-ins

The NNMi Smart Plug-ins (NNM iSPIs) enhance NNMi’s capability to monitor specialized network environments like IP multicast infrastructure or IP telephony network and carry out focused performance analysis of your network components.

Here is the list of NNM iSPIs that are available with NNMi PremiumUltimate:

Network Node Manager iSPI Performance for Metrics Software (NNM iSPI Performance for Metrics)

The NNM iSPI Performance for Metrics provides the following software programs:

Network Performance Server (NPS): NPS provides the infrastructure to analyze the performance characteristics of your network. With the performance data collected by the Network Node Manager i Software Smart Plug-ins (iSPIs), NPS builds data tables, runs queries in response to user selections, and displays query results in web-based reports that enable you to diagnose and troubleshoot problems in your network environment.
NNM iSPI Performance for Metrics: The NNM iSPI Performance for Metrics provides the core performance management capability to NNMi by gathering and monitoring the metric data polled by NNMi from different network elements. The combination of NNMi and NNM iSPI Performance for Metrics enables you to monitor the operational performance of your network infrastructure.

The NNM iSPI Performance for Metrics also provides you with sets of embedded dashboard screens and predefined reports in the form of Extension Packs to analyze the performance data polled by NNMi.

Network Node Manager iSPI Performance for Quality Assurance Software (NNM iSPI Performance for QA)

The NNM iSPI Performance for QA monitors the quality of network service levels discovered by NNMi to ensure network services are performing to the desired levels.

The NNM iSPI Performance for QA also provides the Intelligent Response Agent (iRA), which monitors performance of such response probes on the Windows and Linux systems that NNMi is managing. This allows for more precise source-to-destination tests and prevents additional load on critical network devices.

Network Node Manager iSPI Performance for Traffic Software (NNM iSPI Performance for Traffic)

The NNM iSPI Performance for Traffic tracks and reports on all network traffic in an enterprise that is being collected via the industry-standard NetFlow, JFlow, SFlow, and IPFIX traffic data capture methodologies. It provides aggregated and detailed reports on the volume of traffic flowing between host servers, which can be scoped by individual router interfaces. It can characterize all applications in the system by means of powerful configurable rules and thus presents an integrated view of packet flow in the network.

Network Node Manager iSPI for IP Multicast Software (NNM iSPI for IP Multicast)

The NNM iSPI for IP Multicast extends NNMi to be aware of IP multicast environments. It improves fault isolation for IP multicast applications by automatically discovering and displaying views of multicast nodes and interfaces and their relationships, as well as generating alarms based on events related to the multicast environment.

Network Node Manager iSPI for MPLS Software (NNM iSPI for MPLS)

The NNM iSPI for MPLS monitors multiprotocol label switching (MPLS) service availability and inventory. In addition to traditional Layer 3 virtual private networks (L3 VPN), the NNM iSPI for MPLS handles core, traffic-engineered, and pseudo-wire management (L2 VPN).

Network Node Manager iSPI for IP Telephony Software (NNM iSPI for IP Telephony)

NNM iSPI for IP Telephony provides comprehensive fault and availability management of your business-essential IP telephony service. This iSPI provides discovery and in-depth monitoring for the critical IP telephony infrastructure, including gateways, gateway endpoints and channels, gatekeepers, and IP phones. It also improves efficiency by giving telecom and data teams a common diagnostic and monitoring solution. The NNM iSPI for IP Telephony supports Avaya, Cisco, and Nortel IP telephony systems.

Network Node Manager iSPI Network Engineering Toolset Software (NNM iSPI NET)

NNM iSPI NET delivers key tools and workflow automation for network engineers and operators. It provides workflow automation from an embedded limited-use version of Operations Orchestration software. The NNM iSPI NET also provides trap analytic capabilities and topology export to Microsoft Visio. Both the tools and the workflow automation save operators and engineers time when it is most valuable—during a problem—resulting in faster repairs and less downtime.
