I was able to fix some missing dependencies but I still can't build it all the way. Now I get the following error: ` make[1]: Entering directory '/c/temp/prometheus_rabbitmq_exporter/deps/prometheus_process_collector' |

There was a problem hiding this comment.
I'm sure "undefined" would be the best value here, but it seemed better than zero or MsgCount.

* Remove redundant Dockerfile ARG * Allow overriding DOCKER_BASE_IMAGE when building Docker image * Add make target that allows building ezs in a specific OTP context This was necessary to test that the fixes for #75 work in RabbitMQ v3.7.9 & OTP v21.2.5, the combo that ships in Docker image rabbitmq:3.7.9. This is the first RabbitMQ Docker image that supports prometheus_rabbitmq_exporter (compiled with OTP v21.0.2). Docker image rabbitmq:3.7.8 ships with OTP v20.3.8.5 Notice that I disable prometheus_process_collector in the Docker build context. This fails to build due to Docker image erlang:21.2.5 missing native libs. Didn't want to shave this yak as well. * Fix metric mappings to ETS tables In RabbitMQ v3.7.x, the following mappings were not valid and would result in crashes when a produce/consumer would connect to RabbitMQ: * connection_metrics * connection_recv_count, recv_count * connection_send_count, send_count * channel_queue_metrics * channel_queue_get, get * channel_queue_get_no_ack, get_no_ack * channel_queue_deliver, deliver * channel_queue_deliver_no_ack, deliver_no_ack * channel_queue_redeliver, redeliver * channel_queue_ack, ack * channel_queue_get_empty, get_empty The following metric was mapped incorrectly: * connection_churn_metrics * 7, queue_deleted There is more line churn in this commit than necessary. I was re-formatting all metrics as I was going over all mappings. This confirms that I've checked that all mappings are accurate. I've tested manually against current v3.7.x branch via `make run-broker` as well as rabbitmq:3.7.9 Docker image: make distclean make otp-21.2.5-build-context make /usr/local/bin/elixir apt update && apt install zip make ezs ^D make docker_build DOCKER_BASE_IMAGE=rabbitmq:3.7.9-management docker run -it -p 5672:5672 -p 15672:15672 deadtrickster/rabbitmq_prometheus:3.7 cd ~/github.com/rabbitmq/rabbitmq-perf-test make run ARGS="-x 1 -y 1 -r 1" curl localhost:15672/api/metrics # NO CRASHES! Fixes #75 cc @dcorbacho

Attempt to solve #100. I tried building locally to test it but was unable to. After installing MSYS2 on my Win10 laptop with necessary packages I got errors when running "make deps" (see example below)

I also tried the same with an older version or Erlang (10.2) with same/similar error.
PS: It would be nice to have a section somewhere explaining how to build it.
