/**
 * <p>Enables this Amazon Web Services account to be able to use CloudWatch Application Signals by creating the <i>AWSServiceRoleForCloudWatchApplicationSignals</i> service-linked role. This service- linked role has the following permissions:</p> <ul> <li> <p> <code>xray:GetServiceGraph</code> </p> </li> <li> <p> <code>logs:StartQuery</code> </p> </li> <li> <p> <code>logs:GetQueryResults</code> </p> </li> <li> <p> <code>cloudwatch:GetMetricData</code> </p> </li> <li> <p> <code>cloudwatch:ListMetrics</code> </p> </li> <li> <p> <code>tag:GetResources</code> </p> </li> <li> <p> <code>autoscaling:DescribeAutoScalingGroups</code> </p> </li> </ul> <p>A service-linked CloudTrail event channel is created to process CloudTrail events and return change event information. This includes last deployment time, userName, eventName, and other event metadata.</p> <p>After completing this step, you still need to instrument your Java and Python applications to send data to Application Signals. For more information, see <a href="https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Application-Signals-Enable.html"> Enabling Application Signals</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { ApplicationSignalsClient, StartDiscoveryCommand } from "@aws-sdk/client-application-signals"; // ES Modules import
 * // const { ApplicationSignalsClient, StartDiscoveryCommand } = require("@aws-sdk/client-application-signals"); // CommonJS import
 * // import type { ApplicationSignalsClientConfig } from "@aws-sdk/client-application-signals";
 * const config = {}; // type is ApplicationSignalsClientConfig
 * const client = new ApplicationSignalsClient(config);
 * const input = {};
 * const command = new StartDiscoveryCommand(input);
 * const response = await client.send(command);
 * // {};
 *
 * ```
 *
 * @param StartDiscoveryCommandInput - {@link StartDiscoveryCommandInput}
 * @returns {@link StartDiscoveryCommandOutput}
 * @see {@link StartDiscoveryCommandInput} for command's `input` shape.
 * @see {@link StartDiscoveryCommandOutput} for command's `response` shape.
 * @see {@link ApplicationSignalsClientResolvedConfig | config} for ApplicationSignalsClient's `config` shape.
 *
 * @throws {@link AccessDeniedException} (client fault)
 *  <p>You don't have sufficient permissions to perform this action.</p>
 *
 * @throws {@link ThrottlingException} (client fault)
 *  <p>The request was throttled because of quota limits.</p>
 *
 * @throws {@link ValidationException} (client fault)
 *  <p>The resource is not valid.</p>
 *
 * @throws {@link ApplicationSignalsServiceException}
 * <p>Base exception class for all service exceptions from ApplicationSignals service.</p>
