Method Detail

registerNamespaceSetProperty

public static void registerNamespaceSetProperty(SentinelProperty<Set<String>> property)

Register cluster server namespace set dynamic property.

Parameters:

property - server namespace set dynamic property

registerServerTransportProperty

public static void registerServerTransportProperty(SentinelProperty<ServerTransportConfig> property)

Register cluster server transport configuration dynamic property.

Parameters:

property - server transport configuration dynamic property

registerGlobalServerFlowProperty

public static void registerGlobalServerFlowProperty(SentinelProperty<ServerFlowConfig> property)

Register cluster server global statistic (flow) configuration dynamic property.

Parameters:

property - server flow configuration dynamic property

loadServerNamespaceSet

public static void loadServerNamespaceSet(Set<String> namespaceSet)

Load provided server namespace set to property in memory.

Parameters:

namespaceSet - valid namespace set

loadGlobalTransportConfig

public static void loadGlobalTransportConfig(ServerTransportConfig config)

Load provided server transport configuration to property in memory.

Parameters:

config - valid cluster server transport configuration

loadGlobalFlowConfig

public static void loadGlobalFlowConfig(ServerFlowConfig config)

Load provided server global statistic (flow) configuration to property in memory.

Parameters:

config - valid cluster server flow configuration for global

loadFlowConfig

public static void loadFlowConfig(String namespace,
                                  ServerFlowConfig config)

Load server flow config for a specific namespace.

Parameters:

namespace - a valid namespace

config - valid flow config for the namespace

addTransportConfigChangeObserver

public static void addTransportConfigChangeObserver(ServerTransportConfigObserver observer)

Add a transport config observer. The observers will be called as soon as there are some changes in transport config (e.g. token server port).

Parameters:

observer - a valid transport config observer

isValidTransportConfig

public static boolean isValidTransportConfig(ServerTransportConfig config)

isValidFlowConfig

public static boolean isValidFlowConfig(ServerFlowConfig config)

getExceedCount

public static double getExceedCount(String namespace)

getMaxOccupyRatio

public static double getMaxOccupyRatio(String namespace)

getIntervalMs

public static int getIntervalMs(String namespace)

getSampleCount

public static int getSampleCount(String namespace)

Get sample count of provided namespace.

Parameters:

namespace - valid namespace

Returns:

the sample count of namespace; if the namespace does not have customized value, use the global value

getMaxAllowedQps

public static double getMaxAllowedQps()

getMaxAllowedQps

public static double getMaxAllowedQps(String namespace)

getExceedCount

public static double getExceedCount()

getMaxOccupyRatio

public static double getMaxOccupyRatio()

getNamespaceSet

public static Set<String> getNamespaceSet()

getPort

public static int getPort()

getIdleSeconds

public static int getIdleSeconds()

getIntervalMs

public static int getIntervalMs()

getSampleCount

public static int getSampleCount()

setNamespaceSet

public static void setNamespaceSet(Set<String> namespaceSet)

isEmbedded

public static boolean isEmbedded()

setEmbedded

public static void setEmbedded(boolean embedded)

Set the embedded mode flag for the token server.

NOTE: developers SHOULD NOT manually invoke this method. The embedded flag should be initialized by Sentinel when starting token server.

Parameters:

embedded - whether the token server is currently running in embedded mode

setMaxAllowedQps

public static void setMaxAllowedQps(double maxAllowedQps)
