Top Five Ways to Optimize Performance Monitoring
Network performance monitoring, and especially network optimization, is more of an art than a science because there are so many factors that figure into network and application responsiveness. In addition, while there is a plethora of data on the network, determining the right kind of data that you need and where you should you be capturing it from can become very difficult. This data collection process is then further complicated by the fact that tactical data loses up to 70% of its value after 30 minutes. This makes the speed and accuracy of data analysis critical.
The solution to these problems is to create a network visibility architecture. Network visibility is what enables you to quickly isolate and resolve performance issues; ultimately ensuring the best possible end-user experience. From there, you can use anomaly driven data flows to quickly isolate potential problems.
Here is what you need to set up a visibility architecture:
- Taps, virtual taps, and bypass switches – These devices give you timely access to the data you need
- Network packet broker (NPB) – This device gives you filtering capability to maximize the flow of relevant information to your monitoring tools. NPBs enable: data aggregation, filtering, deduplication, and load balancing of Layer 2 through 4 (of the OSI model) packet data.
- Application intelligence functionality (within an NPB) – This functionality provides additional filtering and analysis at the application layer, i.e. Layer 7 of the OSI stack
- The final layer is made up of your security and monitoring tools. These devices are typically special purpose tools (e.g., sniffer, NPM, APM, etc.) that are designed to analyze specific data.
