Some key monitoring and logging features include: 1. CloudWatch Metrics: You can monitor the health and performance of your load balancer using Amazon CloudWatch metrics, which provide real-time statistics of your instances, traffic distribution, request processing time, and other performance-related parameters. 2. Access Logs: These detailed logs contain information about client requests, enabling you to analyze traffic patterns, identify security issues, and troubleshoot potential problems. 3. CloudTrail Logs: These logs record API calls made to the Elastic Load Balancing service, allowing you to detect unauthorized activity, security breaches, or alterations to your load balancer settings. By utilizing these monitoring and logging features, you can proactively address issues, optimize performance, and maintain the availability, reliability, and security of your applications.
Guide: ELB Monitoring and Logging for AWS Solution Architect Exam
Elastic Load Balancing (ELB) in AWS is a service that automatically distributes incoming application traffic among multiple targets, such as EC2 instances. Importance: ELB monitoring and logging is crucial because it allows you to track the health of your system, identify and mitigate issues, and optimize overall performance. It collects and sends metrics and log files to CloudWatch for detailed analysis. How ELB Monitoring and Logging Works: When enabled, ELB automatically starts monitoring your load balancer and its registered instances and sends metrics to Amazon CloudWatch every minute. Additionally, access logs are enabled, providing detailed records of requests made to your load balancer. Exam Tips: i) Understand the key ELB metrics - such as HealthyHostCount, UnHealthyHostCount, RequestCount, and HTTPCode_ELB_5XX. ii) Know how to enable and disable access logs. iii) Be aware of how to analyze ELB metrics and logs using CloudWatch. Answering Questions on ELB Monitoring and Logging: i) Provide concise, straightforward answers. ii) Always relate your answers to a specific use-case when possible. iii) Be clear on the differences between ELB monitoring and logging, and when to use one over the other. Remember, a strong understanding of ELB monitoring and logging can significantly boost your performance in AWS Solution Architect Exam.
AWS Certified Solutions Architect - ELB Monitoring and Logging Example Questions
