supporting custom multiprocess metric path

1

This pr is about supporting a custom multiprocess metric path, not changing current usage about env PROMETHEUS_MULTIPROC_DIR. I found that MultiProcessCollector supports a path param https://github.com/prometheus/client_python/blob/master/prometheus_client/multiprocess.py#L22, though metrics don't support...

should the project/package name be `prometheus-client` rather than `prometheus_client`

Hey. I stumbled over the question what to use when one specifies the Prometheus Client as a `dependency=` in `pyproject.toml`? - you guys seem to use `prometheus_client` (underscore) https://github.com/prometheus/client_python/blob/46eae7bae88f76951f7246d9f359f2dd5eeff110/pyproject.toml#L6C9-L6C26 -...

Fix server shutdown

**Summary:** When I start a prometheus server, then stop it, then re-start it, server can not restart because port was not released.

This is an idea to try to improve multiprocess collect performance by using rust to collect the metrics from various .db files. Current state of the benchmarks shows a 2x...

Fix #1020

shadchin

Use specific exception for duplicate timeseries

1

Use sub-class of ValueError instead of ValueError, so that we can distinguish issues caused by wrong input (like invalid name format) from duplicate metrics being registered into the same registry.

Add deadlock prevention during metric registration

2

Detect deadlocks during the library misuse, eg. by injecting code into the critical sections that itself might want to obtain the relevant lock. A follow up to #1076.

Feature request - public `registry._names_to_collectors` access

Now we are working on **Prometheus** support in **FastStream** and faced with a problem. Shared registry between different middlewares leads to MetricsContainer duplication. So, we would like to have a...
