%% You can use Amazon CloudWatch Synthetics to continually monitor your
%% services.
%%
%% You can create and manage canaries, which are modular, lightweight scripts
%% that monitor your endpoints and APIs from the outside-in. You can set up
%% your canaries to run 24 hours a day, once per minute. The canaries help
%% you check the availability and latency of your web services and
%% troubleshoot anomalies by investigating load time data, screenshots of the
%% UI, logs, and metrics. The canaries seamlessly integrate with CloudWatch
%% ServiceLens to help you trace the causes of impacted nodes in your
%% applications. For more information, see Using ServiceLens to Monitor the
%% Health of Your Applications in the Amazon CloudWatch User Guide.
%%
%% Before you create and manage canaries, be aware of the security
%% considerations. For more information, see Security Considerations for
%% Synthetics Canaries.

%%
%% Canaries are scripts that monitor your endpoints and APIs from the
%% outside-in. Canaries help you check the availability and latency of your
%% web services and troubleshoot anomalies by investigating load time data,
%% screenshots of the UI, logs, and metrics. You can set up a canary to run
%% continuously or just once.
%%
%% Do not use `CreateCanary' to modify an existing canary. Use UpdateCanary
%% instead.
%%
%% To create canaries, you must have the `CloudWatchSyntheticsFullAccess'
%% policy. If you are creating a new IAM role for the canary, you also need
%% the `iam:CreateRole', `iam:CreatePolicy' and `iam:AttachRolePolicy'
%% permissions. For more information, see Necessary Roles and Permissions.
%%
%% Do not include secrets or proprietary information in your canary names.
%% The canary name makes up part of the Amazon Resource Name (ARN) for the
%% canary, and the ARN is included in outbound calls over the internet. For
%% more information, see Security Considerations for Synthetics Canaries.

%% means that you can put canaries from multiple Regions into the same group,
%% and then use that group to view and manage all of those canaries in a
%% single view.
%%
%% Groups are supported in all Regions except the Regions that are disabled
%% by default. For more information about these Regions, see Enabling a
%% Region.
%%
%% Each group can contain as many as 10 canaries. You can have as many as 20
