AWS Monitoring, Logging, and Optimization Flashcards
| Front | Back |
| How can you monitor AWS Lambda functions? | Using CloudWatch Logs for function output, CloudWatch Metrics for invocation data, and X-Ray for distributed tracing. |
| How do you create a custom CloudWatch dashboard? | Use the CloudWatch console or AWS CLI to create dashboards that display metrics from multiple services in one view. |
| How do you monitor RDS instances in CloudWatch? | RDS automatically sends metrics to CloudWatch including CPU utilization, database connections, and storage metrics. |
| How do you optimize S3 storage costs? | Use storage classes (Standard, IA, Glacier), lifecycle policies, and S3 Analytics to identify cost-saving opportunities. |
| How does AWS Trusted Advisor help with optimization? | It provides real-time recommendations to help optimize AWS infrastructure, improve security, reduce costs, and increase performance. |
| What are AWS Config Rules? | Predefined or custom rules that evaluate if AWS resources comply with your desired configurations. |
| What are CloudWatch Alarms? | CloudWatch service that triggers actions based on metric thresholds, such as sending notifications or executing Auto Scaling policies. |
| What are CloudWatch composite alarms? | Alarms that monitor the states of multiple other alarms to reduce noise and focus on critical issues. |
| What are CloudWatch metric math expressions? | Formulas that allow you to query multiple CloudWatch metrics and use math functions to create new time series. |
| What are EC2 instance status checks? | Two checks that monitor instance availability: system status (AWS infrastructure) and instance status (OS-level issues). |
| What are the five pillars of the AWS Well-Architected Framework? | Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization |
| What are the three types of CloudTrail trails? | 1) Management events 2) Data events 3) Insights events |
| What is a CloudWatch Events rule? | A rule that matches incoming events and routes them to targets for processing. |
| What is a CloudWatch Log Group? | A collection of log streams that share the same retention, monitoring, and access control settings. |
| What is a CloudWatch metric anomaly detection? | A feature that uses machine learning to continuously analyze metrics, determine normal baselines, and surface anomalies. |
| What is Amazon CloudWatch Container Insights? | A monitoring solution for containerized applications and microservices running on ECS, EKS, and Kubernetes on EC2. |
| What is Amazon CloudWatch? | A monitoring and observability service for cloud resources and applications that provides metrics, logs, alarms, and dashboards. |
| What is Amazon DevOps Guru? | A machine learning-powered service that detects operational issues and recommends remediation actions. |
| What is Amazon X-Ray? | A service that helps developers analyze and debug distributed applications, particularly those built using microservices. |
| What is AWS CloudFormation Drift Detection? | A capability that detects when a stack's actual configuration differs from its expected configuration. |
| What is AWS CloudTrail? | A service that records API calls and events for your AWS account to enable governance, compliance, and operational auditing. |
| What is AWS Compute Optimizer? | A service that recommends optimal AWS resources for your workloads to reduce costs and improve performance. |
| What is AWS Config? | A service that assesses, audits, and evaluates configurations of AWS resources for compliance monitoring and troubleshooting. |
| What is AWS Cost Explorer? | A tool that provides visualization of your AWS costs and usage over time with filtering and grouping capabilities. |
| What is AWS Systems Manager? | A management service that helps you automatically collect software inventory, apply OS patches, create system images, and configure systems. |
| What is CloudWatch Logs Insights? | A feature that enables searching and analyzing log data stored in CloudWatch Logs using a purpose-built query language. |
| What is CloudWatch Logs? | A service for collecting, monitoring, and storing log files from EC2 instances, Lambda functions, and other AWS resources. |
| What is the AWS Cost and Usage Report? | The most comprehensive set of AWS cost and usage data available, including additional metadata about AWS services and pricing. |
| What is the difference between CloudWatch basic and detailed monitoring? | Basic monitoring collects metrics at 5-minute intervals (free), while detailed monitoring collects at 1-minute intervals (paid feature). |
| What is the purpose of AWS Service Quotas? | A service to view and manage your quotas for AWS services from one location. |
| What metrics does CloudWatch collect by default for EC2 instances? | Default metrics include CPU utilization, network traffic, disk activity, and status checks at 5-minute intervals (1-minute with detailed monitoring). |
