Custom DataSource for AWS ECS Container Insights Metrics Not Polling
Hi LogicMonitor Community,
We are trying to build a custom AWS_CLOUDWATCH DataSource to collect per-service CPU and memory metrics from AWS ECS Container Insights.
Objective
Our goal is to monitor CPUUtilized and MemoryUtilized for each ECS service in the prod-webapp cluster and display these metrics on a LogicMonitor dashboard.
AWS Validation Completed
We have verified using AWS CLI and CloudWatch that the following metrics are available and returning valid datapoints:
Namespace:
ECS/ContainerInsightsMetrics:
CPUUtilized,MemoryUtilizedDimensions:
ClusterName = prod-cluser-appServiceName = <ecs-service-name>

Current Issue
The DataSource status shows Not in Use, even though the AWS metrics are confirmed to exist and return data through the AWS CLI.
The standard AWS_ECS_ClusterServices DataSource is working correctly in our environment, so AWS credentials and ECS monitoring are functioning as expected.
Question
Has anyone successfully implemented a custom DataSource for ECS Container Insights metrics using AWS_CLOUDWATCH? If so, are there any specific requirements or best practices for:
AppliesTo expressions
Active Discovery configuration
CloudWatch metric path formatting
Multi-instance setup
Any guidance or examples would be greatly appreciated.
Thank you!
