This use case led to a Pacemaker feature many moons ago ...

Pacemaker supports nagios plug-ins as a resource type (e.g.
nagios:check_apache_status). These are service checks usually used with
monitoring software such as nagios, icinga, etc.

If the service being monitored is inside a VirtualDomain, named vm1 for
example, you can configure the nagios resource with the resource meta-
attribute container="vm1". If the nagios check fails, Pacemaker will
restart vm1.

(This feature was added before OS containers became popular, so the
naming is a bit unfortunate.)
