# 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
