Class NodeLabelStats

java.lang.Object
io.jenkins.plugins.smartexecutorloadbalancer.NodeLabelStats
All Implemented Interfaces:
Serializable
public final class NodeLabelStats extends Object implements Serializable
Ring-buffer of recent build records for one (nodeName, labelExpression) combination. The buffer size is controlled by SmartLBConfig.getFailureThreshold() and is applied each time a record is added.

Thread-safety: all mutating methods are synchronized. Read-only accessors snapshot the list to avoid holding the lock.
