Method Detail

clearRegisteredApps

public void clearRegisteredApps()

Cleans out all the registered applications inside of Eureka.

registeredApplications

public List<com.netflix.discovery.shared.Application> registeredApplications()

Returns a list of all the registered applications in Eureka.

Returns:

list of registered applications.

isApplicationRegistered

public boolean isApplicationRegistered(String appId)

Checks to see if a given app is registered in Eureka.

Parameters:

appId - the id of the app to check.

Returns:

true if registered, false otherwise.

getRegisteredApplication

public com.netflix.discovery.shared.Application getRegisteredApplication(String appId)

Returns an Application with given appId if found from Eureka.

Parameters:

appId - the id of the app to check.

Returns:

the registered application if found, otherwise null.

getHeartbeatCount

public long getHeartbeatCount()

Returns the count of heartbeat renewals in Eureka.

Returns:

the number of heartbeats sent to Eureka

Implementation Note:

This requires reflection hacks due to the way Eureka stores the renews and what is visible from this class. I don't like it, but it is what it is. The getNumOfRenewsInLastMin() method calls getCount() on the MeasuredRate which returns the value from the AtomicLong lastBucket. When renews happen, the increment happens on teh AtomicLong currentBucket field which is not publicly accessible.

registerApplication

public void registerApplication(String appName,
                                String instanceId,
                                String vipAddress,
                                String status)

Loads an application instance in Eureka for later retrieval.

Parameters:

appName - the application name

instanceId - the instance id

vipAddress - the VIP address of the instance

status - the status of the instance
