There is no such feature, but :
- an alert was sent to your logs for each down server, and an
emergency message was sent when you lost the last one, so this
should have been detected ;
- you can enable SNMP using the tools in the contrib/ directory
and monitor it just like the rest of your network components ;
- there is a nagios plugin to monitor haproxy and which should
report alerts when servers/proxies are down ;
So in practice, there are several solutions and all can be used at
the same time if you want. I know some people who receive SMS when
one of their servers go down, and I know that others receive mails,
in fact anything can be done when combined with the appropriate
tools.
