public interface ServerLoadProbe extends CacheCallback
The getLoad method will be called once per poll interval see
returned by the getLoad method will be sent to the locator every time the
load for this server changes. To conserve bandwidth, it's a good idea to
round the load calculations so that the load will not be sent too frequently.
ServerLoad object contains two floating point numbers indicating
the load on the server due to client to server connections and due to
subscription connections. When routing a connection, the locator will choose
the server that has the lowest load.
It is generally a good idea to pick a load function where 0 connections corresponds to 0 load. The default gemfire load probes return a fraction between 0 and 1, where 0 indicates no load, and 1 indicates the server is completely loaded.
Because cache servers can be stopped, reconfigured, and restarted, the open and close methods on this callback can be called several times. If the same callback object is installed on multiple cache servers, open and close will be called once for each bridge server.
