Link to repo that use TelemetryMetricsPrometheus #42
Description
Greetings,
I have read Hex documentation for TelemetryMetricsPrometheus, Telemetry.Metrics, OpentelemetryPhoenix
It probably should be enough, but I fail to get content from localhost:9568/metrics. I get a 200 Response, but 0 content-length.
A link to any repo using TelemetryMetricsPrometheus (and Phoenix, if possible), would be much appreciated.
From my application.ex
def start(_type, _args) do
:opentelemetry_cowboy.setup()
OpentelemetryPhoenix.setup(adapter: :cowboy2)
OpentelemetryEcto.setup([:excdf, :repo])
metrics = [
Telemetry.Metrics.last_value("vm.memory.total", unit: :byte),
Telemetry.Metrics.counter("http.request.count", unit: :byte),
Telemetry.Metrics.sum("http.request.payload_size", unit: :byte)
]
children = [
# Start the Telemetry supervisor
ExcdfWeb.Telemetry,
{Phoenix.PubSub, name: ExcdfWeb.PubSub},
{TelemetryMetricsPrometheus, [metrics: metrics]},
# Start the Endpoint (http/https)
ExcdfWeb.Endpoint
]
# See https://hexdocs.pm/elixir/Supervisor.html
# for other strategies and supported options
opts = [strategy: :one_for_one, name: ExcdfWeb.Supervisor]
Supervisor.start_link(children, opts)
end
