Prometheus flask exporter in Gunicorn

Is this needed to be implemented in gunicorn config file? `` def when_ready(server): GunicornPrometheusMetrics.start_http_server_when_ready(8080)

``

I am getting duplication port error.

My config file looks like ` from consul_integration import register_service,deregister_service,instanceID from prometheus_flask_exporter.multiprocess import GunicornPrometheusMetrics

hostname = “0.0.0.0” portname = 8080

def when_ready(server): GunicornPrometheusMetrics.start_http_server_when_ready()

# Called just before the master process is initialized. def on_starting(server): register_service()

def child_exit(server, worker): GunicornPrometheusMetrics.mark_process_dead_on_child_exit(worker.pid)

# Called just before exiting Gunicorn. def on_exit(server): deregister_service(instanceID) `

Solved it. The issue was the prometheus_multiproc_dir variable should be outside from .env

Earlier the same was set from os.environ['prometheus_multiproc_dir'] which wasn’t visible to the downstream processes.

I’ve followed the doc above, but there is only a blank response on /metrics endpoint. as in here: https://github.com/rycus86/prometheus_flask_exporter/tree/master/examples/gunicorn

The same works fine if it is just PrometheusMetrics. Are there any debug modes to be enabled to see what’s happening?
