Hi,

I agree with Logan I am wondering if you can share a use case with multiple 
health monitors.

I have concerns about multiple health monitors on the same pool.  Is this 
always going to be the same type of health monitor?  There's also ambiguity in 
the case where one health monitor fails and another doesn't.  Is it an AND or 
OR that determines whether the member is down or not?

Thanks,
Brandon Logan

Vijay,

Pools-monitors are still many to many, if it's not so on the picture - we'll 
fix that.
I brought this up as an example of how we dealt with m:n via API.

Thanks,
Eugene.

Thanks for the clarification. Eugene.

A tangential point since you brought healthmon and pool.

There will be an additional entity called 'PoolMonitorAssociation' which 
results in a many to many relationship between pool and monitors. Right?

Now, the model is indicating a pool can have only one monitor. So a minor 
correction is required to indicate the many to many relationship via 
PoolMonitorAssociation.

Thanks,
Vijay V.

Hi Vijay,


When you say API is not available, it means this should not be considered like 
a resource/entity. Correct?

But then, there would be API like a bind API, that accepts loadbalancer_id & 
listener_id,  which creates this object.
And also, there would be an API that will be used to list the listeners of a 
LoadBalancer.

Right?
Right, that's the same as health monitors and pools work right now: there are 
separate REST action to associate healthmon to a pool


Thanks,
Eugene.
