This documentation topic is designed for Grafana workspaces that support **Grafana version 9.x**.  
For Grafana workspaces that support Grafana version 12.x, see [Working in Grafana version 12](using-grafana-v12.md).  
For Grafana workspaces that support Grafana version 10.x, see [Working in Grafana version 10](using-grafana-v10.md).  
For Grafana workspaces that support Grafana version 8.x, see [Working in Grafana version 8](using-grafana-v8.md).

You can organize your rules. Rules are created within rule groups, and rule groups are organized into namespaces. The rules within a rule group are run sequentially at a regular interval. The default interval is one minute. You can rename Grafana Mimir or Loki namespaces and rule groups, and edit rule group evaluation intervals.

**To edit a rule group or namespace**

1. From your Grafana console, in the Grafana menu, choose the **Alerting** (bell) icon to open the **Alerting** page.

1. Navigate to a rule within the rule group or namespace you want to edit.

1. Choose the **Edit** (pen) icon.

1. Make changes to the rule group or namespace.
**Note**  
For namespaces, you can only edit the name. For rule groups, you change the name, or the evaluation interval for rules in the group. For example, you can choose `1m` to have the rules be evaluated once per minute, or `30s` to evaluate once every 30 seconds.

1. Choose **Save changes**.
