Clustering enhances your web application's high availability, performance, and Hiking log application that uses the Express framework and an Amazon Relational Database Service (RDS).Įxpress web application that uses Amazon ElastiCache for clustering. While monitoring instance metrics can yield some very helpful alerts, if there is any sort of autoscaling or instance rotation in the environment, creating alarms will be ineffective.Use the procedure at Create an Example Application to launch this example. When these metrics go into an alarm state, we’ll have the alarm invoke the appropriate SNS topic. We typically will deploy these 5 metrics to each environment. Well Architected Framework Elastic Beanstalk Application Latency Chart Recommendation: Monitor ApplicationLatencyP99, create a CloudWatch alarm on the Average statistic. ![]() This metric is measured for both environments and instances, and we want to monitor the environment version. When latency increases, it often means that other issues are imminent. For example, for some applications, 2,500 requests within a 5 minute period will be a lot of requests triggering an alarm Well Architected Framework Elastic Beanstalk EnvironmentHealth ChartĪpplicationLatencyP99 measures 99th percentile for application latency, and can be useful to detect when your application’s performance is suffering. These sums will be different per environment. Recommendation: Monitor and create an alarms on ApplicationRequestsTotal, ApplicationRequests5xx, and ApplicationRequests4xx on the Sum statistic for each metric. ![]() Monitoring the total number of requests can help you pinpoint surges in traffic, while monitoring 5xx and 4xx responses is good error detection.This metric is measured for both environments and instances, and we want to monitor the environment version. In most Elastic Beanstalk environments, we see see multiple degradations within a two week period as seen below Well Architected Framework Elastic Beanstalk EnvironmentHealth Chartīeanstalk measures metrics about the number of requests your application is receiving, as well as the status codes of the responses. Well Architected Framework Elastic Beanstalk Alarm for EnvironmentHealth We’ll also specify an Email endpoint to receive the notification. Next, when the Alarm state trigger is in Alarm, we’ll select an existing SNS Topic to post to. Well Architected Framework Elastic Beanstalk Metric for EnvironmentHealth We’ll configure the conditions to be Static, Greater than 15. The statistic will be set to average over a 5 minute period. Typically, the Alarm will be configured on the Metric name: EnvironmentHealth for the appropriate environment. The Cloud Watch Alarm will be specified in the CloudWatch > Alarms section. Recommendation: Monitor and create an alarm for anything >= 15 (Warning) The most basic Beanstalk metric is EnvironmentHealth, which is an enumeration containing the 7 Beanstalk health statuses as follows: Yes, there’s cost associated with adding these 5 metrics to your AWS environment, but, in our opinion, the costs are well worth it.ĮlasticBeanstalk_Metrics_Cost_Estimate.pdf Our recommendation is to add the following metrics to all of your AWS Elastic Beanstalk environments: Elastic Beanstalk enables you to configure scaling based upon a single metric, but what happens if the problem isn’t with that metric? Well, unfortunately, everything can go to hell. Most people believe that if your Elastic Beanstalk instances run into problems, then AWS will just spin up new instances. We’ve seen a number of poorly configured Elastic Beanstalk environments. Which Metrics to Monitor for you Elastic Beanstalk Environment
