Chapter 21. URL Response Time Monitoring

Part of web application performance is determined by how responsive it is to requests. JBoss Operations Network supplies an extra monitoring setting called response time filters which measures the amount of time it takes for a URL to respond to a request.

21.1. Call-Time (or Response Time) Monitoring for URLs

Performance for web applications is more complex than simple availability. How quickly an application can respond to requests is as important as whether the application is running.
The time that it takes an application to respond to some kind of request is call-time or response time data.
Two types of resources support call-time data by default:
  • Session beans, for EJB method calls.
  • Web servers (standalone or embedded in an application server), for URL responses. Web servers require an additional response time filter with configuration on what URL resources to measure for response times.
Response time monitoring is more based upon performance than it is on capturing a single data point. Response or call-time data are displayed as aggregates, showing maximum, minimum, and average response times per URL or per method.
