+=== Dependencies
+
+APM agents collect details about external calls made from instrumented services.
+Sometimes, these external calls resolve into a downstream service that's instrumented -- in these cases,
+you can utilize <<distributed-tracing,distributed tracing>> to drill down into problematic downstream services.
+Other times, though, it's not possible to instrument a downstream dependency --
+like with a database or third-party service.
+**Dependencies** gives you a window into these uninstrumented, downstream dependencies.
+
+[role="screenshot"]
+image::apm/images/dependencies.png[Dependencies view in the APM app in Kibana]
+
+Many application issues are caused by slow or unresponsive downstream dependencies.
+And because a single, slow dependency can significantly impact the end-user experience,
+it's important to be able to quickly identify these problems and determine the root cause.
+
+Select a dependency to see detailed latency, throughput, and failed transaction rate metrics.
+
+[role="screenshot"]
+image::apm/images/dependencies-drilldown.png[Dependencies drilldown view in the APM app in Kibana]
+
+When viewing a dependency, consider your pattern of usage with that dependency.
+If your usage pattern _hasn't_ increased or decreased,
+but the experience has been negatively effected -- either with an increase in latency or errors,
+there's likely a problem with the dependency that needs to be addressed.
+
+If your usage pattern _has_ changed, the dependency view can quickly show you whether
+that pattern change exists in all upstream services, or just a subset of your services.
+You might then start digging into traces coming from
+impacted services to determine why that pattern change has occurred.
