 Hi,

 With varnishstat, I don't seem to be able to monitor how many of my
 backends are healthy.  For example:

 [root at serverd ~]# varnishstat -1 |grep -i backend
 backend_conn           130195         0.45 Backend connections success
 backend_unhealthy            0         0.00 Backend connections not
 attempted
 backend_busy                0         0.00 Backend connections too many
 backend_fail                0         0.00 Backend connections failures
 backend_reuse               0         0.00 Backend connections reuses
 backend_recycle             0         0.00 Backend connections recycles
 backend_unused              0         0.00 Backend connections unused
 n_backend                   4          .   N backends
 backend_req            130008         0.45 Backend requests made
 [root at serverd ~]#

 This says I've four backends, but it's not showing anywhere that 1 of my 4
 backends is sick.

 Is this information available so that it can be added to Zabbix / Nagios?
