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.
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.
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
Log into console, navigate to Cloudwatch -> Metrics -> ContainerInsights/Prometheus -> “ClusterName, Namespace” , you should see the below metrics for the namespace
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.
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.
