Class AuditLogStorage

java.lang.Object

io.jenkins.plugins.auditlogger.AuditLogStorage

public class AuditLogStorage
extends Object

Production-grade audit log storage. Design for heavy load: - Lock-free ConcurrentLinkedQueue for incoming events (zero blocking on callers) - Single daemon writer thread drains queue and writes batches - Persistent BufferedWriter (no open/close per entry) - Bounded in-memory ring buffer (ArrayDeque + ReadWriteLock) for UI/API queries - Automatic file rotation on size threshold - Proper shutdown with flush guarantee - Data masking integrated before persistence

Method Summary

Modifier and Type	Method	Description
void	addEntry(AuditLogEntry entry)	Record an audit event.
List<AuditLogEntry>	filterEntries(String username, String action, Long startTime, Long endTime)	Filter entries by criteria.
List<AuditLogEntry>	getAllEntries()	Get all entries in memory (most recent MAX_ENTRIES_IN_MEMORY).
AnomalyDetector	getAnomalyDetector()	Get the anomaly detector instance for querying alerts.
static AuditLogStorage	getInstance()
boolean	hasEntries()	Fast existence check used by the UI to avoid loading every entry during page render.
void	initialize()	Initialize storage: ensure dirs, load recent logs, start writer thread.
void	shutdown()	Flush all pending writes and shut down the writer thread.

Method Details

getInstance

public static AuditLogStorage getInstance()

initialize

public void initialize()

Initialize storage: ensure dirs, load recent logs, start writer thread. Called once during plugin startup.

addEntry

public void addEntry(AuditLogEntry entry)

Record an audit event. Non-blocking — entry is queued for async disk write. Returns immediately; typical latency < 1 microsecond.

getAllEntries

public List<AuditLogEntry> getAllEntries()

Get all entries in memory (most recent MAX_ENTRIES_IN_MEMORY). Returns a defensive copy.

hasEntries

public boolean hasEntries()

Fast existence check used by the UI to avoid loading every entry during page render.

getAnomalyDetector

public AnomalyDetector getAnomalyDetector()

Get the anomaly detector instance for querying alerts.

filterEntries

public List<AuditLogEntry> filterEntries(String username,
 String action,
 Long startTime,
 Long endTime)

Filter entries by criteria. Returns a defensive copy.

shutdown

public void shutdown()

Flush all pending writes and shut down the writer thread. Called on plugin stop.
