Class Alert

java.lang.Object

org.wpilib.driverstation.Alert

frc.spectrumLib.telemetry.Alert

All Implemented Interfaces:

AutoCloseable

public class Alert
extends Alert

A WPILib Alert that is also logged and shown on Elastic.

WPILib 2027 alpha-6 sends alerts to the Driver Station through the HAL only. They are not published to /SmartDashboard/Alerts, so Elastic's Alerts widget stays empty. There is no API to list them, so AdvantageKit's alert logger never sees them either. This subclass keeps its own registry: periodic() records the active alerts as outputs (Alerts/Errors, Alerts/Warnings, Alerts/Infos, newest first, as the 2026 dashboard showed them) and republishes them in the /SmartDashboard/Alerts group Elastic reads.

A drop-in replacement: same constructors and methods, and Alert.Level still refers to WPILib's levels.
