Does Collage have onlinne-offline management?

[leo07046219]

I find ping() and pingIdleNodes() cmd,but donot find the online state management of the nodes.
Does Collage maintain the nodes' state via heartbeat and provide state request api, or on/off line callback reg api?
If not, any suggestion for me to build it myself?

Thanks very much!

Collage can detect dead nodes, but iirc does not reconnect them automatically. Equalizer uses this to remove them from a running configuration: http://eyescale.github.io/equalizergraphics.com/documents/design/nodeFailure.html

I don't recall if reconnects are possible, but theoretically you can try to relaunch it.

Thx.
Ok，Collage detect the nodes via the api-calling. I may try the reconnect action.

This is my applicationScenarios. And try to apply collage to it.

I want some suggestion about the application of Collage, to match the requirement in the the scenarios above.
1.Is is right?
2.how the proxyNode works, I don't think the proxyNode is necessary?
3.and I do not know the best way to build 2-way link between mainboard and subboard——mainboard may initiate a data send action. Just place a new local node and a proxy node in board,and a new local node in subboard?

thanks!
