similar to https://github.com/grpc-ecosystem/go-grpc-prometheus in python.
Installation from PyPI:
pip install python-grpc-prometheus
Check the available interceptors in the source code. This example uses the PromServerInterceptor.
Usage example:
import grpc
from concurrent.futures import ThreadPoolExecutor
# Importing this whole package so that I can use prometheus_client.start_http_server()
# instead of just start_http_server(), which is not too descriptive. But it's your call.
import prometheus_client
from python_grpc_prometheus.prometheus_server_interceptor import PromServerInterceptor
# Add the required interceptor(s) where you create your grpc server, e.g.
psi = PromServerInterceptor()
server = grpc.server(ThreadPoolExecutor(max_workers=10), interceptors=(psi,))
# Start the http server where prometheus can fetch the data from. Use whatever listen port you prefer.
prometheus_client.start_http_server(8000)
# ...Now, when running your application, you can check http://localhost:8000 in a browser.
Note: the grpc_* metrics will just show commented out (with their descriptions) until your application actually receives gRPC calls.
