Method Detail

init

void init(PeerEurekaNodes peerEurekaNodes)
   throws java.lang.Exception

Throws:

java.lang.Exception

syncUp

int syncUp()

Populates the registry information from a peer eureka node. This operation fails over to other nodes until the list is exhausted if the communication fails.

shouldAllowAccess

boolean shouldAllowAccess(boolean remoteRegionRequired)

Checks to see if the registry access is allowed or the server is in a situation where it does not all getting registry information. The server does not return registry information for a period specified in EurekaServerConfig.getWaitTimeInMsWhenSyncEmpty(), if it cannot get the registry information from the peer eureka nodes at start up.

Returns:

false - if the instances count from a replica transfer returned zero and if the wait time has not elapsed, otherwise returns true

register

void register(com.netflix.appinfo.InstanceInfo info,
              boolean isReplication)

statusUpdate

void statusUpdate(java.lang.String asgName,
                  ASGResource.ASGStatus newStatus,
                  boolean isReplication)
