Record Class ClusterSnapshot

java.lang.Record

com.societegenerale.failover.observable.metrics.ClusterSnapshot

Record Components:

instanceId - the emitting instance's identifier (e.g. orders-service:host-7)

summary - that instance's local KPI snapshot

configEntries - that instance's @Failover configuration, from FailoverConfigSnapshotService; never null — a missing value (older peer, or the 2-arg constructor) normalises to empty

public record ClusterSnapshot(String instanceId, MetricsSummary summary, List<ConfigEntry> configEntries)
extends Record

The payload one instance pushes to the dashboard in cluster.mode=shared-store: its own identity plus the local MetricsSummary snapshot and its @Failover configuration. The receive time is stamped server-side on ingest (the peer clock is not trusted for liveness), so it is intentionally not part of this record.

Constructor Details

ClusterSnapshot

public ClusterSnapshot(String instanceId,
 MetricsSummary summary,
 List<ConfigEntry> configEntries)

Normalises a null configEntries (e.g. an older stored row) to an empty list.

ClusterSnapshot

public ClusterSnapshot(String instanceId,
 MetricsSummary summary)

Backward-compat: no configuration payload.

Parameters:

instanceId - the emitting instance's identifier

summary - that instance's local KPI snapshot

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

instanceId

public String instanceId()

Returns the value of the instanceId record component.

Returns:

the value of the instanceId record component

summary

public MetricsSummary summary()

Returns the value of the summary record component.

Returns:

the value of the summary record component

configEntries

public List<ConfigEntry> configEntries()

Returns the value of the configEntries record component.

Returns:

the value of the configEntries record component
