Application Dependency Maps gives you a complete overview of your application's connections with its external components. You get a bird's eye view of your application's communications like fetching data from databases, storing data in the cache, sending out RSS feeds and more.
Key metrics like response time, throughput, and failed count are listed out for external dependencies, allowing you to gauge the performance metrics at a single glance. Any errors in your application or external dependencies are marked out visibly, enabling you to take immediate action before your customers are impacted.
You can also check the status of your application instances with these maps. The average response time, failed request count and total requests for respective components are listed out separately, and each of the enlisted components can be drilled down further for further analysis.
