How do I reload my Prometheus Yml file?
Prometheus can reload your configuration at runtime. If the new configuration is not well formed, the changes will not be applied. A configuration reload is triggered by sending a SIGHUP to the Prometheus process or by sending an HTTP POST request to the /-/reload endpoint (when the –web.enable-lifecycle flag is enabled).
