# 使用 AWS CLI 的 Application Discovery Service 示例 以下代码示例演示如何通过将 AWS Command Line Interface与 Application Discovery Service 结合使用，来执行操作和实现常见场景。 *操作是大型程序的代码摘录*，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。 每个示例都包含一个指向完整源代码的链接，您可以从中找到有关如何在上下文中设置和运行代码的说明。 **Topics** + [操作](#actions) ## 操作 ### `describe-agents` 以下代码示例演示了如何使用 `describe-agents`。 **AWS CLI** **描述具有指定 collectionStatus 状态的座席** 此示例命令描述收集状态为“已启动”或“已停止”的收集座席。 命令: ``` aws discovery describe-agents --filters name="collectionStatus",values="STARTED","STOPPED",condition="EQUALS" --max-results 3 ``` 输出： ``` { "Snapshots": [ { "version": "1.0.40.0", "agentType": "EC2", "hostName": "ip-172-31-40-234", "collectionStatus": "STOPPED", "agentNetworkInfoList": [ { "macAddress": "06:b5:97:14:fc:0d", "ipAddress": "172.31.40.234" } ], "health": "UNKNOWN", "agentId": "i-003305c02a776e883", "registeredTime": "2016-12-09T19:05:06Z", "lastHealthPingTime": "2016-12-09T19:05:10Z" }, { "version": "1.0.40.0", "agentType": "EC2", "hostName": "ip-172-31-39-64", "collectionStatus": "STARTED", "agentNetworkInfoList": [ { "macAddress": "06:a1:0e:c7:b2:73", "ipAddress": "172.31.39.64" } ], "health": "SHUTDOWN", "agentId": "i-003a5e5e2b36cf8bd", "registeredTime": "2016-11-16T16:36:25Z", "lastHealthPingTime": "2016-11-16T16:47:37Z" } ] } ``` + 有关 API 详细信息，请参阅《AWS CLI 命令参考》**中的 [DescribeAgents](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/discovery/describe-agents.html)。 ### `describe-configurations` 以下代码示例演示了如何使用 `describe-configurations`。 **AWS CLI** **描述选定的资产配置** 此示例命令描述两台指定服务器的配置。该操作会从配置 ID 中检测资产类型。每个命令只允许使用一种类型的资产。 命令: ``` aws discovery describe-configurations --configuration-ids "d-server-099385097ef9fbcfb" "d-server-0c4f2dd1fee22c6c1" ``` 输出： ``` { "configurations": [ { "server.performance.maxCpuUsagePct": "0.0", "server.performance.maxDiskReadIOPS": "0.0", "server.performance.avgCpuUsagePct": "0.0", "server.type": "EC2", "server.performance.maxNetworkReadsPerSecondInKB": "0.19140625", "server.hostName": "ip-172-31-35-152", "server.configurationId": "d-server-0c4f2dd1fee22c6c1", "server.tags.hasMoreValues": "false", "server.performance.minFreeRAMInKB": "1543496.0", "server.osVersion": "3.14.48-33.39.amzn1.x86_64", "server.performance.maxDiskReadsPerSecondInKB": "0.0", "server.applications": "[]", "server.performance.numDisks": "1", "server.performance.numCpus": "1", "server.performance.numCores": "1", "server.performance.maxDiskWriteIOPS": "0.0", "server.performance.maxNetworkWritesPerSecondInKB": "0.82421875", "server.performance.avgDiskWritesPerSecondInKB": "0.0", "server.networkInterfaceInfo": "[{\"name\":\"eth0\",\"macAddress\":\"06:A7:7D:3F:54:57\",\"ipAddress\":\"172.31.35.152\",\"netMask\":\"255.255.240.0\"},{\"name\":\"lo\",\"macAddress\":\"00:00:00:00:00:00\",\"ipAddress\":\"127.0.0.1\",\"netMask\":\"255.0.0.0\"},{\"name\":\"eth0\",\"macAddress\":\"06:A7:7D:3F:54:57\",\"ipAddress\":\"fe80::4a7:7dff:fe3f:5457\"},{\"name\":\"lo\",\"macAddress\":\"00:00:00:00:00:00\",\"ipAddress\":\"::1\"}]", "server.performance.avgNetworkReadsPerSecondInKB": "0.04915364583333333", "server.tags": "[]", "server.applications.hasMoreValues": "false", "server.timeOfCreation": "2016-10-28 23:44:00.0", "server.agentId": "i-4447bc1b", "server.performance.maxDiskWritesPerSecondInKB": "0.0", "server.performance.avgDiskReadIOPS": "0.0", "server.performance.avgFreeRAMInKB": "1547210.1333333333", "server.performance.avgDiskReadsPerSecondInKB": "0.0", "server.performance.avgDiskWriteIOPS": "0.0", "server.performance.numNetworkCards": "2", "server.hypervisor": "xen", "server.networkInterfaceInfo.hasMoreValues": "false", "server.performance.avgNetworkWritesPerSecondInKB": "0.1380859375", "server.osName": "Linux -
