[Out of scope] Support for SASP?

[artur]

Are you planning on providing support for Server/Application State Protocol (SASP, http://tools.ietf.org/html/draft-bivens-sasp-04) in xr at some point?

Artur,

That's not really on the roadmap, or at least it hasn't been so far. Is it something you need?

So far, tbh, least-connections dispatching and web interface scripting have solved it all, albeit through non-standard approaches. I'm even thinking of having a separate SASP program that communicates with XR (via the web interface) and with a SASP-manager, because all that SASP can do and asks (e.g.., weights, register/deregister and so on) is in XR. SASP in this form could be a good add-on though.

I don't really need it but I am looking at ways of providing health/load data back to the balancer. I was looking for standards so we can be compatible with many balancers and came across SASP. I'm not sure how wildly it is used. Some Cisco balancers support it but SNMP seems to be the preferred protocol for obtaining such data.

Artur,

I've heard of SNMP usage before, but not SASP. So yeah, I agree that SNMP might be more generic or more widely used.

Incidentally, having an SNMP prober on the XR box that queries the back ends, and tells XR what weights should apply, is pretty trivial. I would prefer a separate prober as opposed to bloating the daemon code.
