A comprehensive review of network performance monitors
A collection of articles that takes you from defining technology needs to purchasing options
Editor's note: This HPE Network Node Manager i product overview is part of a series on network performance monitoring. The series also explores the evolution of network monitoring technology, discusses the major use cases, lays out the major purchasing criteria and compares the leading vendors on the market.
Hewlett Packard Enterprise (HPE) has been in the network monitoring business longer than anyone. Its Network Node Manager i (NNMi) is used by thousands of customers -- primarily very large, enterprise-class organizations and telecommunications companies.
Among the primary advantages of NNMi is its ability to scale to very large sizes, as well as the flexibility users have to create customized environments that can become largely automated. NNMi comes in two different enterprise versions: NNMi Premium and NNMi Ultimate. Both offer standard network fault monitoring and performance metrics out of the box. The primary difference between Premium and Ultimate boils down to what optional NNMi Smart Plug-ins (iSPIs) can be installed with the base NNMi product. NNMi can be installed on a number of server operating systems, including Windows Server, HP-UX and Linux. The following iSPIs are available to install with each edition:
NNM iSPI Performance for Metrics: This plug-in lets administrators collect granular device, interface and end-to-end performance metrics, as well as display the results in an easy-to-understand format. This plug-in can be installed on both Premium and Ultimate editions.
NNM iSPI Performance for Quality Assurance: This plug-in is ideal for enterprises and service providers that must monitor and adhere to strict service-level agreements.
NNM iSPI Performance for Traffic: This is HPE's NetFlow collector plug-in for NNMi. The tool can collect several standard flow protocols, including NetFlow, J-Flow, sFlow and IPFIX. NNMi Ultimate edition is required to use this plug-in.
NNM iSPI for IP Telephony: The telephony plug-in offers detailed monitoring and diagnostics of IP telephony infrastructure, such as voice gateways, gatekeepers and IP phones. It supports leading enterprise-class communications tools, including those from Avaya and Cisco. NNMi Ultimate edition is required to use this plug-in.
NNM iSPI for IP Multicast: For networks with large multicast deployments, the IP multicast plug-in can automatically discover multicast nodes and interfaces, as well as establish data flow relationships. This information can be used to speed up the troubleshooting process when multicast performance begins to suffer. NNMi Ultimate edition is required to use this plug-in.
NNM iSPI for MPLS: Primarily meant for telco service providers, the MPLS plug-in adds monitoring and performance tuning capabilities for Layer 2 and Layer 3 VPN MPLS deployments. NNMi Ultimate edition is required to use this plug-in.
NNM iSPI Network Engineering Toolset: This plug-in is a series of tools that assist network engineers in automating and orchestrating repetitive processes within the NNMi platform. NNMi Ultimate edition is required to use this plug-in.
Pricing and support
Licensing for HPE Network Node Manager i can be purchased on a per-device or per-interface basis. To add a bit more flexibility, customers can choose from one of two licensing tiers that provide either more or less monitoring capabilities on a per-device basis. So, if you require relatively simple monitoring on a subset of devices on your network, you can choose to purchase the lower-priced license tier.
HPE offers several support tiers, ranging from software upgrades and online support to options that include personalized troubleshooting for global NNMi deployments.
