Cloud Monitoring

Definition

Cloud monitoring is the process of reviewing, managing, and monitoring the operational workflow in a cloud-based IT infrastructure. It involves the use of automated tools and services to track the performance, availability, and security of cloud resources, ensuring they function optimally and securely. Effective cloud monitoring helps in identifying potential issues, optimizing resource usage, and maintaining compliance with security policies.

Secure Settings Example

# Example of a secure AWS CloudWatch configuration
logs:
  logGroupName: "/aws/lambda/my-function"
  retentionInDays: 30
  metricFilter:
    filterPattern: "[timestamp=*Z, request_id=\"*-*\", event]"
    metricTransformations:
      - metricName: "ErrorCount"
        metricNamespace: "MyApp"
        metricValue: "1"
  alarms:
    - alarmName: "HighErrorRate"
      metricName: "ErrorCount"
      namespace: "MyApp"
      statistic: "Sum"
      period: 300
      evaluationPeriods: 1
      threshold: 5
      comparisonOperator: "GreaterThanOrEqualToThreshold"
      actionsEnabled: true
      alarmActions:
        - "arn:aws:sns:us-east-1:123456789012:NotifyMe"

Insecure Settings Example

# Example of an insecure AWS CloudWatch configuration
logs:
  logGroupName: "/aws/lambda/my-function"
  retentionInDays: 0  # Logs are not retained
  metricFilter:
    filterPattern: ""  # No filter pattern defined
    metricTransformations: []
  alarms:
    - alarmName: "HighErrorRate"
      metricName: "ErrorCount"
      namespace: "MyApp"
      statistic: "Sum"
      period: 300
      evaluationPeriods: 1
      threshold: 100  # High threshold, may miss critical alerts
      comparisonOperator: "GreaterThanOrEqualToThreshold"
      actionsEnabled: false  # No actions taken on alarm
