| `nodeSelector` | `string` | `nil` | Limiting the nodes which are processed. Only used when `nodeFit`=`true` and only by the PreEvictionFilter Extension Point. |
| `maxNoOfPodsToEvictPerNode` | `int` | `nil` | Maximum number of pods evicted from each node (summed through all strategies). |
| `maxNoOfPodsToEvictPerNamespace` | `int` | `nil` | Maximum number of pods evicted from each namespace (summed through all strategies). |
| `maxNoOfPodsToEvictTotal` | `int` | `nil` | Maximum number of pods evicted per rescheduling cycle (summed through all strategies). |
| `metricsCollector` | `object` | `nil` | Configures collection of metrics for actual resource utilization. |
| `metricsCollector.enabled` | `bool` | `false` | Enables Kubernetes [Metrics Server](https://kubernetes-sigs.github.io/metrics-server/) collection. |
| `evictionFailureEventNotification` | `bool` | `false` | Enables eviction failure event notification. |
