The entity spike alert

The entity spike alert detects when entity count in any world rises sharply above its normal level. Because it uses a per-world baseline rather than a server-wide absolute number, it adapts to servers where one world normally has a high entity count and another normally has very few.

What triggers it

The alert fires when any world's entity count reaches three times its 7-day average. The 7-day average is recalculated continuously, so the threshold adjusts as your server's normal state changes over time. A server that gradually accumulates more entities over weeks will see the threshold rise to match, while a sudden spike still stands out clearly.

What the alert contains

The alert email includes:

• The name of the world that triggered the alert
• The current entity count in that world and its 7-day average
• Current TPS at the time of the alert
• A link to your analytics dashboard's entity breakdown panel

Common causes

Most entity spikes have an identifiable cause, in rough order of frequency:

• Mob farm overflow: the kill mechanism stopped working while the spawning continued. Mobs and items accumulate rapidly
• Storage full on automated farms: when hoppers and chests fill up, items start dropping onto the ground as entities
• Players clearing inventory: a player dropping a full inventory in a busy area leaves a pile of item entities
• Large explosions: creeper chains or TNT create many falling block entities simultaneously
• Experience orb accumulation: XP orbs from mob farms or large battles pile up before merging or despawning
