What Is an Eviction Threshold?
An eviction threshold is a configured limit on a node resource like available memory, disk, or inodes, below which the node agent begins evicting pods to recover. Soft thresholds allow a grace period while hard thresholds act immediately. Pods are chosen by QoS class and priority.
Why it matters
Thresholds protect the node itself from running completely out of resources and crashing. Tuning them trades earlier, gentler evictions against the risk of a hard node failure.
