Setup

Enable prometheus metrics in wasmd:

Edit $HOME/config/app.toml

[telemetry]

# Enabled enables the application telemetry functionality. When enabled,
# an in-memory sink is also enabled by default. Operators may also enabled
# other sinks such as Prometheus.
enabled =true
# ...

# PrometheusRetentionTime, when positive, enables a Prometheus metrics sink.
prometheus-retention-time = 15

retention-time must be >0 (see prometheus scrape config)

Edit $HOME/config/config.toml

[instrumentation]

# When true, Prometheus metrics are served under /metrics on
# PrometheusListenAddr.
# Check out the documentation for the list of available metrics.
prometheus = true

Test manually at: http://localhost:1317/metrics?format=prometheus

Note the format parameter in the request for the endpoint:
