# Filtering Kubernetes entities

By default, groundcover traces all namespaces and workloads in your cluster, but sometimes you want to block ones that are irrelevant to your needs, or alternatively only allow something very specific.

groundcover allows you to add **traces filtering rules** on specific workloads and namespaces by creating a custom `values.yaml` file.\
\
The rules are a list of **regex patterns with its matching type (allow / block)** that represents the entities you want groundcover filter.

## Usage

The following overrides need to be added to your `values.yaml` configuration file. After updating the file use the [installing & updating](/getting-started/installation-and-updating/connect-kubernetes-cluster.md) instructions to apply the changes.

```yaml
tracesNamespaceFilters:
  - matchType: "allow"
    regex: "my-namespace"
tracesWorkloadFilters:
  - matchType: "block"
    regex: "do-not-show-me"
```
