Hi Varun,

Could you tell me which driver you are using? If you're running the
HaproxyOnHostPluginDriver then that should do a check every 6 seconds
for members being down.  However, other drivers may not do this.  It's
up to the driver.

As for providing health monitor stats, those currently are not being
provided.  There haven't been any plans for that yet because everyone
has been focused on getting the v2 API out.  Which is almost complete
and plan for that to be completed for Kilo-3.  If you'd like to be able
to retrieve some health stats, please list them and let us know.  We'll
hopefully be able to get them in after v2 has completed.
