What are custom metrics used for in AWS?
- Configuring IAM policies
- Monitoring network traffic
- Monitoring server hardware metrics
- Monitoring specific application or business metrics
Custom metrics in AWS are used for monitoring specific application or business metrics that are not available by default through AWS services.
How are custom metrics typically created in AWS?
- Automatic discovery by CloudWatch
- Manual configuration through the AWS Management Console
- Using AWS Lambda functions
- Using the CloudWatch API
Custom metrics in AWS are typically created using the CloudWatch API, allowing developers to programmatically send data to CloudWatch for monitoring.
What are some best practices for using custom metrics in AWS?
- Define meaningful metrics
- Ignore anomalies
- Monitor regularly
- Use default alarms
Best practices for using custom metrics in AWS include defining meaningful metrics that align with business objectives, regularly monitoring metrics, and investigating anomalies rather than ignoring them.
