Hello, I would like the propose adding to mysqld_exporter the ability to /-/reload the scraper configuration. Currently scrapers are only configurable via --collect.<name>[.arg] and cannot be reconfigured at runtime, so this proposal also entails allowing collectors to be configured via a file, and then to have the ability to reconfigure scrapers when the contents of that file change and /-/reload is called.
I opened a GH issue here <https://github.com/prometheus/mysqld_exporter/issues/759>. It was closed by Ben saying that the maintainers had no plans to implement, but didn't say whether they would be open to a contribution, which I'd be happy to offer if so. The reason this would be useful to me is that my organization runs mysqld_exporter in a container co-located with a mysqld container in the same Kubernetes pod. mysqld has a socket but no port so there's no way to reconfigure the mysqld_exporter container without recreating the pod. I realize this situation may not be common, but hopefully this idea would be generally useful and merit consideration here. I have prototyped a solution locally that works pretty well and is fully backwards compatible.
