Prometheus on EC2 & ECS:

Some helpers for anyone configuring Prometheus on ECS and AWS EC2.

To get started on AWS ECS and EC2:

For EC2/ECS nodes:

Import the ecs task definition and add cadvisor and node-exporter service/task definition and run them on each host you want to be monitored
Any hosts which have "Monitoring: On" tag will be automatically added in the targets
Expose ports 9100 and 9191 to your Prometheus host

For Prometheus host:

Copy prometheus.yml configuration present here to base prometheus configuration to enable EC2 service discovery
docker compose up -d

Note: Set query.staleness-delta to 1m make metrics more realtime

TODO

Add alerting rules based on ECS
