Canister Monitoring with Prometheus

This is an example project to show how to monitor a canister written in Motoko using Prometheus. The canister exposes a /metrics HTTP endpoint that encodes important metrics in a text based format Prometheus understands. You can customize the metrics in the metrics function.

The Prometheus configuration can be adapted by changing the configuration files in the prometheus folder. In particular you can change the alert.yml to create customized alerts.

Requirements

• Docker

Usage

docker compose up

The Prometheus user interface will be available at https://localhost:9000.

If you make changes run docker compose build before docker compose up.

Authorization

This example uses an API key to control access to the metrics endpoint.

Troubleshooting

If you're running this on a M1 Mac you might need to run DOCKER_DEFAULT_PLATFORM=linux/amd64 docker-compose up.
