# Node Observability

> The following guide describes the observability capabilities of Towns Stream Nodes and how to monitor and manage them.

Stream nodes expose `/metrics` to export Prometheus metrics on port `443`. The metrics are exposed in the Prometheus format and can be scraped by a Prometheus server. Both `process_` and `river_` prefixed metrics are exportable.

Below are the required environment variables for the **Towns Stream Node Container** related to telemetry:

| Environment Variable | Value | Secret |
| -------------------- | ----- | ------ |
| METRICS\_\_ENABLED   | true  | no     |
| LOG\_\_FORMAT        | json  | no     |
| LOG\_\_LEVEL         | info  | no     |
| LOG\_\_NOCOLOR       | true  | no     |
