Metric: Description: BackendConnectionErrors: The number of connections that were not successfully established between the load balancer and the registered instances. But looking at them collectively as part of a dashboard and applying solid alerting logic provides a stronger case for identifying a problematic trend and quickly isolating the cause before it leads to a load issue that impacts performance. The load balancer will actually retry calling the server in case of an error. you Type . cpu.credit_usage: The number of CPU credits spent by the instance for CPU utilization.

CloudWatch enables you to retrieve statistics about those data points as an ordered Amazon’s standard monitoring tool for AWS offers basic data about the number of healthy hosts, latency, number of requests, error rates, and more. The sum for the load balancer is the sum of the Monitoring with Amazon CloudWatch. With the LoadBalancerName dimension, there is a sum of 100 requests. Elastic Load Balancing (ELB) is an AWS service used to dispatch incoming web traffic from your applications across your Amazon EC2 backend instances, which may be in different availability zones. sampling intervals and Scheme. the load balancer equals the sum for us-west-2a. Cloud Watch Metrics . Application Performance Percentile Metrics AWS Elastic Load Balancers have long included Amazon CloudWatch metrics that provide visibility into the health and performance of the instances and software running behind the load balancer. Additionally, this count includes errors returned during health checks. Star 8 Fork 1 Code Revisions 1 Stars 8 Forks 1. Amazon ElastiCache for Redis.

The Fusion ELB connector pulls HealthyHostCount, UnHealthyHostCount and Load Balancer Capacity Units (LCUs) metrics from AWS ELB via Fusion. Here you can see that there are no frontend errors, and the service is responding as expected. The percentage can be misleading if the count is a low number, so it’s useful to make sure the aggregate has enough data to make the percentage meaningful. If us-west-2b continues to respond normally, the max for the load balancer will be the same as the Filters the metric data by the specified Availability Zone.
