DataOps Dashboard App

CloudWatch dashboard module for MDAA observability features.

Overview

The DataOps Dashboard App creates CloudWatch dashboards that aggregate metrics and logs from multiple Lambda functions across different modules. It supports SSM-based metric references for cross-module integration and automatic widget layout.

Features

• Text Widgets: Display markdown content for dashboard headers and descriptions
• Metric Widgets: Visualize time-series metrics with support for metric math
• Log Insights Widgets: Display CloudWatch Logs Insights query results
• SSM References: Reference metrics from other modules using SSM Parameter Store
• Placeholder Resolution: Automatically resolve function names and log groups
• Auto-wrapping: Widgets automatically wrap at 24-unit width

Configuration

Basic Dashboard

projectName: my-project
dashboards:
  - dashboardName: etl-observability
    widgets:
      - type: text
        markdown: |
          # ETL Observability Dashboard
          Monitoring for data pipeline
        width: 24
        height: 2

Metric Widget with SSM Reference

- type: metric
  title: "Error Count"
  width: 12
  height: 6
  metrics:
    - metricRef: "ssm:/mdaa/org/dev/metrics/lambda_csv_parquet/error-count"
      stat: Sum

Metric Widget with Direct Reference

- type: metric
  title: "Lambda Duration"
  width: 12
  height: 6
  metrics:
    - namespace: AWS/Lambda
      metricName: Duration
      dimensions:
        FunctionName: "{{function:lambda_csv_parquet}}"
      stat: Average

Log Insights Widget

- type: log_insights
  title: "Recent Errors"
  width: 24
  height: 6
  logGroupNames:
    - "{{function:lambda_csv_parquet:logGroup}}"
  queryString: |
    fields @timestamp, @message
    | filter @message like /ERROR/
    | sort @timestamp desc
    | limit 20

Placeholders

Function Name Placeholder

Use {{function:functionName}} to reference a Lambda function name from SSM:

dimensions:
  FunctionName: "{{function:lambda_csv_parquet}}"

Resolves to: /mdaa/lambda/lambda_csv_parquet/name

Log Group Placeholder

Use {{function:functionName:logGroup}} to reference a Lambda function's log group:

logGroupNames:
  - "{{function:lambda_csv_parquet:logGroup}}"

Resolves to: /mdaa/lambda/lambda_csv_parquet/log-group

SSM Metric References

Reference metrics created by other modules using SSM syntax:

metricRef: "ssm:/mdaa/{org}/{env}/metrics/{functionName}/{metricName}"

The construct will automatically resolve:

• Namespace from: /mdaa/{org}/{env}/metrics/{functionName}/{metricName}/namespace
• Name from: /mdaa/{org}/{env}/metrics/{functionName}/{metricName}/name

Deployment

1. Deploy Lambda functions with metric filters first
2. Wait for SSM parameters to be created
3. Deploy dashboards

# Deploy Lambda functions
cd packages/apps/dataops/dataops-lambda-app
cdk deploy

# Deploy dashboards
cd packages/apps/dataops/dataops-dashboard-app
cdk deploy

Widget Types

Text Widget

- type: text
  markdown: "# Dashboard Title"
  width: 24
  height: 2

Metric Widget

- type: metric
  title: "Metric Title"
  width: 12
  height: 6
  period: 300
  metrics:
    - namespace: AWS/Lambda
      metricName: Duration
      stat: Average

Log Insights Widget

- type: log_insights
  title: "Query Title"
  width: 24
  height: 6
  logGroupNames:
    - "/aws/lambda/my-function"
  queryString: |
    fields @timestamp, @message
    | sort @timestamp desc

Widget Layout

Widgets are automatically laid out in rows with a maximum width of 24 units. When adding a widget would exceed 24 units, a new row is started automatically.

Example:

• Widget 1: width 12 (row 1)
• Widget 2: width 12 (row 1)
• Widget 3: width 12 (row 2, new row started)
• Widget 4: width 12 (row 2)
