Configuring Prometheus on Fly.io

Fly.io (opens in a new tab) provides a hosted Prometheus instance for every project.

To have Fly's Prometheus scrape your Autometrics-instrumented app, simply add this to your fly.toml configuration (opens in a new tab):

app = "your-app-name"
 
[metrics]
port = 9091 # default for most prometheus clients
path = "/metrics" # default for most prometheus clients
