Class HealthState

java.lang.Object
  weblogic.health.HealthState

All Implemented Interfaces:

Serializable

public final class HealthState

extends Object

implements Serializable

This class encapsulates the health information returned by a Server Service. Services register with the server self-health monitor service and provide health information through this class.

Serialized Form

HEALTH_OK

public static final int HEALTH_OK

Server Service is healthy.

See Also:

Constant Field Values

HEALTH_WARN

public static final int HEALTH_WARN

Service could have problems in the future. Check the server logs and the corresponding RuntimeMBean for more details.

See Also:

Constant Field Values

HEALTH_CRITICAL

public static final int HEALTH_CRITICAL

Something must be done now to prevent service failure. Check the server logs and the corresponding RuntimeMBean for more details.

See Also:

Constant Field Values

HEALTH_FAILED

public static final int HEALTH_FAILED

Service has failed - must be restarted. Check the server logs and the corresponding RuntimeMBean for more details.

See Also:

Constant Field Values

HEALTH_OVERLOADED

public static final int HEALTH_OVERLOADED

Service is functioning normally but there is too much work in it. CRITICAL and OVERLOADED are different. A subsystem is in critical state when a part of it is malfunctioning e.g stuck threads. An overloaded state means that there is more work assigned to the Service than the configured threshold. A service might refuse more work in this state.

See Also:

Constant Field Values

LOW_MEMORY_REASON

public static final String LOW_MEMORY_REASON

Reason code that indicates that the server is low on memory. Administrators can configure low and high thresholds for memory usage and the server health changes to OVERLOADED with this reason code if the low threshold is reached.

See Also:

OverloadProtectionMBean, Constant Field Values

getSubsystemName

public String getSubsystemName()

Name of the service providing health information

getState

public int getState()

Health state returned by this service. Can be one of HEALTH_OK, HEALTH_WARN, HEALTH_CRITICAL, HEALTH_FAILED, HEALTH_OVERLOADED

compareSeverityTo

public int compareSeverityTo(HealthState other)

Compares the severity of the supplied HealthState to this object's severity. BUG12620669 necessitated the need to logically compare the severity of different health state objects which could be done by getState() except the logical order is wrong where FAILED < OVERLOADED.

Parameters:

other -

Returns:

a negative integer, zero, or a positive integer as this object's severity is less than, equal to, or greater than supplied object's severity.

compareSeverityTo

public int compareSeverityTo(int otherState)

compareSeverities

public static int compareSeverities(int aState,
                                    int baseState)

getReasonCode

@Deprecated
public String[] getReasonCode()

Deprecated. 

List of reasons corresponding to the current HealthState.

toString in class Object

toCompositeData

public CompositeData toCompositeData()
                              throws OpenDataException

Converts a ConsumerInfo instance to a CompositeData representation.

Returns:

Throws:

OpenDataException - Thrown when an error occurs while constructing the CompositeData representation.

getCompositeType

protected CompositeType getCompositeType()
                                  throws OpenDataException

Throws:

OpenDataException

getCompositeDataMap

protected Map getCompositeDataMap()
                           throws OpenDataException

creates a map of attribute values for use in CompositeData construction

Throws:

OpenDataException

getSymptoms

public Symptom[] getSymptoms()

Get symptoms for this health state

getPartitionName

public String getPartitionName()
