监控AWS CloudWatch for Windows实例中的内存使用情况

Question

默认情况下，CloudWatch不会监视内存使用情况。 所以我尝试使用这些说明将它添加到AWS中的Windows实例。

这就是我做的：

1. 我创建了一个名为custom-metrics-user 。 然后我存储了访问和密钥。

2. 我创建了一个内联策略并将其附加到用户。 它看起来像这样：

    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": ["cloudwatch:PutMetricData", "cloudwatch:GetMetricStatistics", "cloudwatch:ListMetrics", "ec2:DescribeTags"], "Resource": "*" } ] } 

3. 我推出了Windows实例[2012 R2 Base AMI]。 通过RDP访问实例后，我发现AWS.EC2.Windows.CloudWatch.json文件已经存在。

4. 我相应地更改了.json文件。 更改后，它看起来像这样：

    { "EngineConfiguration": { "PollInterval": "00:00:15", "Components": [ { "Id": "ApplicationEventLog", "FullName": "AWS.EC2.Windows.CloudWatch.EventLog.EventLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogName": "Application", "Levels": "1" } }, { "Id": "SystemEventLog", "FullName": "AWS.EC2.Windows.CloudWatch.EventLog.EventLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogName": "System", "Levels": "7" } }, { "Id": "SecurityEventLog", "FullName": "AWS.EC2.Windows.CloudWatch.EventLog.EventLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogName": "Security", "Levels": "7" } }, { "Id": "ETW", "FullName": "AWS.EC2.Windows.CloudWatch.EventLog.EventLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogName": "Microsoft-Windows-WinINet/Analytic", "Levels": "7" } }, { "Id": "IISLog", "FullName": "AWS.EC2.Windows.CloudWatch.IisLog.IisLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogDirectoryPath": "C:\\\\inetpub\\\\logs\\\\LogFiles\\\\W3SVC1" } }, { "Id": "CustomLogs", "FullName": "AWS.EC2.Windows.CloudWatch.CustomLog.CustomLogInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "LogDirectoryPath": "C:\\\\CustomLogs\\\\", "TimestampFormat": "MM/dd/yyyy HH:mm:ss", "Encoding": "UTF-8", "Filter": "", "CultureName": "en-US", "TimeZoneKind": "Local" } }, { "Id": "PerformanceCounter", "FullName": "AWS.EC2.Windows.CloudWatch.PerformanceCounterComponent.PerformanceCounterInputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "CategoryName": "Memory", "CounterName": "Available MBytes", "InstanceName": "", "MetricName": "Memory", "Unit": "Megabytes", "DimensionName": "InstanceId", "DimensionValue": "{instance_id}" } }, { "Id": "CloudWatchLogs", "FullName": "AWS.EC2.Windows.CloudWatch.CloudWatchLogsOutput,AWS.EC2.Windows.CloudWatch", "Parameters": { "AccessKey": "", "SecretKey": "", "Region": "us-east-1", "LogGroup": "Default-Log-Group", "LogStream": "{instance_id}" } }, { "Id": "CloudWatch", "FullName": "AWS.EC2.Windows.CloudWatch.CloudWatch.CloudWatchOutputComponent,AWS.EC2.Windows.CloudWatch", "Parameters": { "AccessKey": "AKIAIK2U6EU675354BQ", "SecretKey": "nPyk9ntdwW0y5oaw8353fsdfTi0e5/imx5Q09vz", "Region": "us-east-1", "NameSpace": "System/Windows" } } ], "Flows": { "Flows": [ "PerformanceCounter,CloudWatch" ] } } } 

5. 我在EC2ConfigSettings下启用了CloudWatch Logs集成。

6. 我重新启动了EC2Config服务。

我没有收到任何错误，但内存指标未显示在Cloud Watch控制台中。 博客说要等待10-15分钟才能显示指标，但自从我完成它已经过了一个小时。 出了什么问题？

首先，您需要向实例添加IAM角色：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowAccessToSSM",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:PutMetricData",
                "logs:CreateLogGroup",
                "logs:CreateLogStream",
                "logs:DescribeLogGroups",
                "logs:DescribeLogStreams",
                "logs:PutLogEvents"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

请注意，您无法将角色添加到现有实例。 所以在发布之前这样做。 然后，您需要通过以下路径配置EC2Config文件（通常）：

C:\\Program Files\\Amazon\\Ec2ConfigService\\Settings.AWS.EC2.Windows.CloudWatch.json

您应该将以下块添加到JSON文件：

...

{
    "Id": "PerformanceCounter",
    "FullName": "AWS.EC2.Windows.CloudWatch.PerformanceCounterComponent.PerformanceCounterInputComponent,AWS.EC2.Windows.CloudWatch",
    "Parameters": {
        "CategoryName": "Memory",
        "CounterName": "Available MBytes",
        "InstanceName": "",
        "MetricName": "Memory",
        "Unit": "Megabytes",
        "DimensionName": "InstanceId",
        "DimensionValue": "{instance_id}"
    }
}

...

{
    "Id": "CloudWatch",
    "FullName": "AWS.EC2.Windows.CloudWatch.CloudWatch.CloudWatchOutputComponent,AWS.EC2.Windows.CloudWatch",
    "Parameters": 
    {
        "AccessKey": "",
        "SecretKey": "",
        "Region": "eu-west-1",
        "NameSpace": "PerformanceMonitor"
    }
}

更改配置文件后，请不要忘记重新启动服务器上的EC2Config服务。 您应该能够在CloudWatch控制台中几分钟后获取内存指标。 您的实例上的CloudWatch监控级别也应设置为详细信息：

更新：

根据文档 ，您现在可以将IAM角色附加或修改为现有实例。

Answer 2

我正在运行Windows 2012 Base R2 Server，它运行的EC2Config版本大于4.0。 如果有人遇到同样的问题，请在重新启动EC2Config服务后重新启动Amazon SSM代理服务。

我在以下链接中阅读[ STEP-6 ]：

http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/send_logs_to_cwl.html

它读取以下内容：

如果您运行的是EC2Config 4.0或更高版本，则必须从Microsoft服务管理单元重新启动实例上的SSM代理。

这样做我解决了我的问题。
