OpenTelemetry

Smallweb supports OpenTelemetry for monitoring and tracing. To activate it, just set the OTEL_DENO environment variable to true before starting the server.

OTEL_DENO=true smallweb up

By default, it will send traces, metrics and logs to http://localhost:4317. You can wire it to self-hosted grafana instance with the following docker-command:

docker run --name lgtm -p 3000:3000 -p 4317:4317 -p 4318:4318 --rm -ti \
    -v "$PWD"/lgtm/grafana:/data/grafana \
    -v "$PWD"/lgtm/prometheus:/data/prometheus \
    -v "$PWD"/lgtm/loki:/data/loki \
    -e GF_PATHS_DATA=/data/grafana \
    docker.io/grafana/otel-lgtm:0.8.1

You can use a bunch of OTEL_ prefixed env variables to configure opentelemetry. If you want to use grafana cloud (they have a generous free tier), you can follow this guide.

Checkout the Deno Docs to learn more about opentelemetry support in deno.
