%% @doc Amazon CloudWatch Application Insights
%%
%% Amazon CloudWatch Application Insights is a service that helps you detect
%% common problems with your applications.
%%
%% It enables you to pinpoint the source of issues in your applications
%% (built with technologies such as Microsoft IIS, .NET, and Microsoft SQL
%% Server), by providing key insights into detected problems.
%%
%% After you onboard your application, CloudWatch Application Insights
%% identifies, recommends, and sets up metrics and logs. It continuously
%% analyzes and correlates your metrics and logs for unusual behavior to
%% surface actionable problems with your application. For example, if your
%% application is slow and unresponsive and leading to HTTP 500 errors in
%% your Application Load Balancer (ALB), Application Insights informs you
%% that a memory pressure problem with your SQL Server database is occurring.
%% It bases this analysis on impactful metrics and log errors.
