Prometheus Metrics

CloudWatch Container Insights monitoring for Prometheus automates the discovery of Prometheus metrics from containerized systems and workloads. Prometheus is an open-source systems monitoring and alerting toolkit.

Prometheus Metrics Logs

The CloudWatch agent supports the standard Prometheus scrape configurations as documented in scrape_config in the Prometheus documentation. The CloudWatch agent YAML that we set up in the chapter enable-prometheus-metrics-in-cloudwatch have jobs configured that are scraped, and the metrics are sent to CloudWatch.

Log events from Amazon EKS and Kubernetes clusters are stored in the /aws/containerinsights/cluster_name/prometheus LogGroup in Amazon CloudWatch Logs.

Log into console, navigate to Cloudwatch -> LogGroups, you should see /aws/containerinsights/eksworkshop-eksctl/prometheus LogGroup, select this and you should be able to see the metrics for all the containers logged here. \[Image NOT FOUND\]

Prometheus Metrics

The CloudWatch agent with Prometheus support automatically collects metrics from services and workloads. Prometheus metrics collected from Amazon EKS and Kubernetes clusters are in the ContainerInsights/Prometheus namespace.

Log into console, navigate to Cloudwatch -> Metrics -> ContainerInsights/Prometheus -> “ClusterName, Namespace” , you should see the below metrics for the namespace prodcatalog-ns. Select any of the metrics (as in below example envoy_cluster_upstream_cx_rx_bytes_total) to add to the graph. You can find the complete list of Prometheus Metrics for App Mesh here. \[Image NOT FOUND\]

Prometheus Report

In the CloudWatch console, Container Insights provides pre-built reports for App Mesh in Amazon EKS and Kubernetes clusters.

To see the pre-built reports on App Mesh Prometheus metrics, Log into console, navigate to Cloudwatch -> “Performance monitoring” -> “Container Insights”, select EKS Prometheus App Mesh in first dropdown and select the EKS cluster in second dropdown. \[Image NOT FOUND\]
