Introducing Network and Application Performance Monitoring – the new equation for faster problem-solving

Organisations are increasingly dependent on the performance of their business applications – which, in turn, depend on the performance of their network infrastructure.ビジネスを順調に運営するためには、アプリケーションとネットワークの両パフォーマンスを最高水準に維持する必要があります。

従来のアプローチでは、異なるシステムを使用する別々のチームが、ネットワークとアプリケーションのパフォーマンスを個別に監視してきました。However, this is becoming more difficult as virtualisation extends from the data centre to the desktop and the use of cloud services continues to grow.ハイブリッド・クラウド環境でアプリケーションの問題が生じたとき、組織はいかにして、問題が自社のインフラに存在するのか、あるいはクラウド・プロバイダー側のインフラに存在するのか、判断できるのでしょうか。Trying to work out who owns a problem when all groups are reporting green KPIs is increasingly difficult and time-consuming.

A recent survey* of network professionals conducted by NETSCOUT indicated that more than half do not have the tools they need to quickly and accurately identify issues with VoIP, applications and other network performance issues.Organisations need end-to-end visibility across layers 1-7, from the data centre to the branch office, if they are to identify the source of any performance problems quickly and solve them before incurring costly downtime.

そこで登場したのが、ネットワークおよびアプリケーションのパフォーマンス・モニタリングNetwork and Application Performance Monitoring, which is also referred to as Network Performance Monitoring and Diagnostics (NPMD).

ネットワークおよびアプリケーションのパフォーマンス・モニタリング は、ネットワークとアプリケーションの双方の監視、解析およびトラブルシューティングを行う手段です。It takes an application-centric view of everything happening across the network, providing end-to-end visibility of the network and applications and their interdependencies, and enabling engineers to monitor and optimise the end user experience.プログラミングの観点からではなく、どのように展開され、どのようなパフォーマンスを発揮しているかという観点でアプリケーションを見ます。

アプリケーションとネットワークの両パフォーマンスのデータ・ポイントを活かすネットワークおよびアプリケーションのパフォーマンス・モニタリングは、IT 部門全体が協力して、アプリケーションとネットワークから最高のパフォーマンスを引き出せるようにします。仮想化、BYOD、クラウドベース・サービスが作り出す可視性の問題を克服し、ネットワーク・パス上のどこであっても、問題を特定できるようにエンジニアを助けます。また、ユーザーが遅い応答時間を経験している時や、どのアプリケーション・コンポーネントが遅延の原因となっているかを特定するためのアプリケーション・パフォーマンス・データを提供します。このすぐに使えるパフォーマンス・データをアプリケーション・チームと共有することで、問題の原因とどのコンポーネントに注意が必要かを突き止められます。

In the data centre, organisation can realise tangible benefits from gaining visibility into where and when the network is busy.The ability to distinguish between critical business use and non-critical or recreational use, showing data in a form factor which they understand, helps to identify quickly which links need additional bandwidth and which can be reduced.This enables better control of IT budgets, allowing for future expansion through the analysis of growth patterns in application use.

Strictly speaking Network and Application Performance Monitoring is defined as giving visibility across LAN, WAN and data centre environments – including all tiers of the server and application environment, whether virtual or physical – as well as layers 1-7, while supporting rates from 1 to 10Gbps.The Network and Application Performance Monitoring solution developed by NETSCOUT extends this further by adding the ability to monitor and troubleshoot the wireless infrastructure and to support remote locations through a portable form factor if more in-depth visibility is needed – providing comprehensive visibility from the data centre to the user device.

Network and Application Performance Monitoring provides seven key benefits:

  • End-to-end infrastructure visibility - it brings together key data points from network management systems (NMS) and application performance management systems, providing a single dashboard view and helping engineers monitor KPIs and track device performance and usage.
  • Faster problem-solving – different IT teams can work together using common tools to resolve issues.
  • Improved user experience – applications can exist in many different places and different infrastructure tiers, making it difficult to discover root cause of problems, but Network and Application Performance Monitoring enables teams to monitor all levels of the user experience and address issues before they become serious.
  • Enhanced productivity – by speeding up MTTR (mean time to resolution), Network and Application Performance Monitoring reduces expensive downtime and improves overall quality of service.
  • Cost savings – an Network and Application Performance Monitoring solution eliminates the need to use multiple tools to monitor the network and application infrastructure.
  • Improved infrastructure optimisation – Network and Application Performance Monitoring enables engineers to identify poor performance and prioritise projects such as server upgrades, make the business case for approval and verify the results.It also provides data to support capacity planning.
  • Better business understanding of IT - Network and Application Performance Monitoring helps executives understand the cost of running critical applications and the impact if they go offline, as well as the dependencies between critical applications and the supporting infrastructure.

ネットワークおよびアプリケーションのパフォーマンス・モニタリング・システムの主な特長

Network and Application Performance Monitoring provides performance data from both network and applications, including stream-to-disk packet storage, application response time analytics, IPFIX (NetFlow) and SNMP.A performance map enables users to watch over the entire enterprise network and isolate individual elements, transactions or even packets, either real time or back in time.

Data is shown on a single dashboard so everyone can see network and application performance metrics.Users can customise the dashboard to suit their individual responsibilities, but they can also see adjacent areas, so cross-functional teams can work together to solve problems and know that they are all seeing the same information.

If a link has errors or high utilisation, they can use a mouse to dive deeper into the transaction and find out why it might be introducing latency to all the upstream transactions.Every device in the path can be analysed (Figure 1).Simple logical workflows enable the user to isolate a problem down to the individual network element, transaction or even packet behind any performance event – real time or historic.

An Network and Application Performance Monitoring system stores all data flows, transactions and packets, so engineers can reconstruct events, use flow forensics for back-in-time identification of traffic on key links, and even play back VoIP calls and video streams.This is particularly useful for solving historic problems.It helps monitor SLAs and links to the cloud to ensure providers are meeting their SLAs, and assess where extra bandwidth might be needed by showing instant real-time bandwidth usage.

However you implement it, Network and Application Performance Monitoring is something we can expect to hear a lot more about in data centres in 2014.
