Failure in one or more of your external components, such as your database, Memcache, or HTTP connections, can slow down your application's performance. With Application Dependency Maps, you can easily identify failed components and their metrics like average response time, failed request, total request, and throughput. 

Mapping all transactions with their respective components eliminates the need for searching. View the transactions involved in calling an external component by clicking the View Components tab. You can then analyze these transactions to pinpoint the exact problem. This helps you contextually debug your application's slowness.
