Where’s the latency occurring? The Network or The Application?

Application Response-Time Monitoring

When the user says, “the network is slow today” or “this application is unresponsive,” where do you look to

verify the user’s experience? This is a difficult question because there has been no easy way to directly

relate the user’s experience to data that helps distinguish between network and application problems. Having

measurements that reflect the user’s experience of network performance enables you to more quickly

identify the source of performance degradation and resolve problems before users even notice. Application

response-time monitoring provides these measurements and can serve as a general barometer of network

performance.

By implementing ART monitoring, the NAM can collect response-time statistics on client/server requests and

responses. By enabling application response-time monitoring, the NAM collects and reports response-time

statistics for critical devices attached to any port or interface. In addition, response-time analysis and

reporting is fully customizable, allowing you to define the time increments by which your applications and

servers are measured, giving you full control over response-time reporting. You can also retrieve response-

time data to collect and determine trends of this data over time. With data like this, you can correlate

changes in network and application usage with fluctuations in response times to predict how changes in user

populations will impact application performance. That is valuable information to have!
