I'm not sure if people have asked for this, but I would love a custom field/column in the Stats Report web page.
Specifically, I would like to be able to see my backend server version. This is a custom text string which I could provide a health-check-like URL to populate. Then the HAProxy stats page could be a one-stop page to watch during rolling upgrades of backends. Probably for easy customization, an external call to third party script would be ideal. Has anyone considered this before? Is there any way to hack existing features to do this? Cheers, --Joel
