/**
 * <p>Gets the current health status (<code>Healthy</code>, <code>Unhealthy</code>, or
 *     <code>Unknown</code>) of one or more instances that are associated with a specified
 *    service.</p>
 *          <note>
 *             <p>There's a brief delay between when you register an instance and when the health status for
 *     the instance is available. </p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { ServiceDiscoveryClient, GetInstancesHealthStatusCommand } from "@aws-sdk/client-servicediscovery"; // ES Modules import
 * // const { ServiceDiscoveryClient, GetInstancesHealthStatusCommand } = require("@aws-sdk/client-servicediscovery"); // CommonJS import
 * // import type { ServiceDiscoveryClientConfig } from "@aws-sdk/client-servicediscovery";
 * const config = {}; // type is ServiceDiscoveryClientConfig
 * const client = new ServiceDiscoveryClient(config);
 * const input = { // GetInstancesHealthStatusRequest
 *   ServiceId: "STRING_VALUE", // required
 *   Instances: [ // InstanceIdList
 *     "STRING_VALUE",
 *   ],
 *   MaxResults: Number("int"),
 *   NextToken: "STRING_VALUE",
 * };
 * const command = new GetInstancesHealthStatusCommand(input);
 * const response = await client.send(command);
 * // { // GetInstancesHealthStatusResponse
 * //   Status: { // InstanceHealthStatusMap
 * //     "<keys>": "HEALTHY" || "UNHEALTHY" || "UNKNOWN",
 * //   },
 * //   NextToken: "STRING_VALUE",
 * // };
 *
 * ```
 *
 * @param GetInstancesHealthStatusCommandInput - {@link GetInstancesHealthStatusCommandInput}
 * @returns {@link GetInstancesHealthStatusCommandOutput}
 * @see {@link GetInstancesHealthStatusCommandInput} for command's `input` shape.
 * @see {@link GetInstancesHealthStatusCommandOutput} for command's `response` shape.
 * @see {@link ServiceDiscoveryClientResolvedConfig | config} for ServiceDiscoveryClient's `config` shape.
 *
 * @throws {@link InstanceNotFound} (client fault)
 *  <p>No instance exists with the specified ID, or the instance was recently registered, and
 *    information about the instance hasn't propagated yet.</p>
 *
 * @throws {@link InvalidInput} (client fault)
 *  <p>One or more specified values aren't valid. For example, a required value might be missing, a
 *    numeric value might be outside the allowed range, or a string value might exceed length
 *    constraints.</p>
 *
 * @throws {@link ServiceNotFound} (client fault)
 *  <p>No service exists with the specified ID.</p>
 *
 * @throws {@link ServiceDiscoveryServiceException}
 * <p>Base exception class for all service exceptions from ServiceDiscovery service.</p>
 *
 *
 * @example GetInstancesHealthStatus example
 * ```javascript
 * // This example gets the current health status of one or more instances that are associate with a specified service.
 * const input = {
 *   ServiceId: "srv-e4anhexample0004"
 * };
 * const command = new GetInstancesHealthStatusCommand(input);
 * const response = await client.send(command);
 * /* response is
 * {
 *   Status: {
 *     i-abcd1234: "HEALTHY",
 *     i-abcd1235: "UNHEALTHY"
 *   }
 * }
 * *\/
 * ```
 *
 * @example Get instances health status using service ARN for shared namespace
 * ```javascript
 * // This example gets the current health status of instances using a service ARN instead of service ID. This is useful for checking health status of instances associated with shared namespaces.
 * const input = {
 *   ServiceId: "arn:aws:servicediscovery:us-west-2:123456789012:service/srv-e4anhexample0004"
 * };
 * const command = new GetInstancesHealthStatusCommand(input);
 * const response = await client.send(command);
 * /* response is
 * {
 *   Status: {
 *     i-abcd1234: "HEALTHY",
 *     i-abcd1235: "UNHEALTHY"
 *   }
 * }
