Question

我的Cloudformation模板中有一个用于Lambda函数的Cloudwatch Dashboard小部件，例如

---
AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Resources:
  MyLambda:
    Type: AWS::Serverless::Function
    ...

  MyStateMachine:
    Type: "AWS::StepFunctions::StateMachine"
    ...

  MyDashboard:
    Type: AWS::CloudWatch::Dashboard
    Properties:
      DashboardName: MyDashboard
      DashboardBody:
        Fn::Sub: '{
          "widgets": [
              {
                  "type": "metric",
                  "x": 0,
                  "y": 3,
                  "width": 24,
                  "height": 3,
                  "properties": {
                      "view": "singleValue",
                      "metrics": [
                          [ "AWS/Lambda", "Invocations", "FunctionName", "${MyLambda}", { "stat": "Sum", "period": 86400 } ],
                          [ ".", "Duration", ".", ".", { "stat": "Average", "period": 86400, "color": "#2ca02c" } ],
                          [ ".", "Errors", ".", ".", { "stat": "Sum", "period": 86400, "color": "#d62728" } ],
                          [ ".", "Throttles", ".", ".", { "stat": "Sum", "period": 86400, "color": "#ff7f0e" } ]
                      ],
                      "region": "us-west-2",
                      "title": "MyLambda", 
                      "stacked": true
                  }
              }
          ]
      }'

我想将MyStateMachine的小部件添加到此信息中心，但我不知道如何编写等效的状态机，

[ "AWS/Lambda", "Invocations", "FunctionName", "${MyLambda}", { "stat": "Sum", "period": 86400 } ]

我发现AWS/Lambda被调用AWS Namespace而等效的AWS/States被Invocations发现all the options我可以用来代替FunctionName，但是我不确定如何替换InstanceId。 This建议我可以使用currentTimeMillis()，但除此之外的文档数量有限。

如何为状态机创建AWS Cloudwatch仪表板小部件？

我通过在AWS Web Console中创建小部件然后查看它生成的源来解决这个问题。以下对我有用。

                      "title": "MyLambda",
                    "stacked": true
                  }
+              },
+              {
+                  "type": "metric",
+                  "x": 0,
+                  "y": 9,
+                  "width": 24,
+                  "height": 3,
+                  "properties": {
+                      "view": "timeSeries",
+                      "metrics": [
+                          [ "AWS/States", "ActivitiesStarted", "ActivityArn", "${MyStateMachine}", { "stat": "Sum", "period": 86400 } ]
+                      ],
+                      "region": "us-west-2",
+                      "title": "State Machine Metrics",
+                      "period": 300
+                  }
               }
           ]
       }'
