The commands named on the Modrinth page of SentinelLag:
/lagsentinelLagSentinel is a lightweight Minecraft server performance management plugin designed to automatically detect extreme lag, purge lag sources (dropped items & entity spam), freeze heavy redstone machinery, and secure the server against potential crashes using a live countdown system and emergency auto-restart.
Dual-Tier Emergency Countdown:
Critical Mode (TPS 30 redstone changes in 5 seconds or >50 entities).
Delivers real-time warning updates directly to all players' screens every second when the server enters an emergency state.
/lagsentinel resume_redstone
Unfreezes redstone flow across all locked chunks.
lagsentinel.admin (OP)
/lagsentinel toggle
Toggles the automatic TPS monitoring system on or off
lagsentinel.admin (OP)
Unlike typical heavy optimization plugins that ruin the vanilla experience-such as completely breaking item farms, limiting useful mechanics like rocket fireworks, or artificially capping mob behaviors-LagSentinel focuses purely on precision and safety. It doesn't interfere with your gameplay or restrict fun mechanics during normal play; it only steps in as an intelligent safety net during actual server emergencies, freezing only the specific overloaded chunks and purging only excessive lag spam while keeping your legitimate builds, items, and farms completely intact.
