I'm pretty new to Prometheus and according to my understanding, there are many metrics already available in Prometheus. But I'm not able to see "http_requests_total" which is used in many examples in the list. Do we need to configure anything in order to avail these HTTP metrics?
My requirement is to calculate the no: of HTTP requests hitting the server at a time. So http_request_total or http_requests_in_flight metrics would be of great help for usage.
Can someone please guide me here on what to do next?
The documentation is extensive and helpful.
See installation
If you have Docker, you can simply run:
docker run \
--interactive --tty --rm \
--publish=9090:9090 \
prom/prometheus
And then browse: http://localhost:9090.
The default config is set to scrape itself.
You can list these metrics.
And graph prometheus_http_requests_total them.
