PMM2 Prometheus feature request
I'd like to request a feature, if possible, if it wasn't already on your radar. This feature would help with the Alertmanager setup I have.
Right now, when an alert gets created using prometheus rules (and then routed through alertmanager) alertmanager will send an e-mail. In the e-mail, beneath the body of the alert is a link "source", this link is supposed to link back to your Prometheus instance and show you a simple chart of the timeframe where the alert happened. In the PMM2 link, though, the URL defaults to "localhost:9090" and as far as I can tell there is no obvious way to modify that. I did a bit of research into Prometheus, and it looks like the way I would fix this if I had full control of the Prometheus instance would be to simply add "--web.external-url=http://mydomain/prometheus" to the startup command when starting Prometheus. But, since that step is handled as custom PMM startup, I don't think I can change that parameter.
If there is a way to do this, please let me know, otherwise a way to change that would be greatly appreciated.
