Finding out number of healthy backends

[Glen Kelly]

Is there any way of using varnishstat to determine the number of healthy backends?

I currently use 'varnishstat -1 -f n_backend' but this only returns the number of backends, not the number of healthy backends.

I am using Nagios to monitor our environment and want to be able to monitor when we lose a backend. I already am monitoring the backends directly so I have that covered but I want to also monitor when varnish thinks it has lost a backend. i.e. monitoring at multiple levels

If this is not current achievable how do I go about requesting this feature to be added to varnish?

Regards Glen
