# Edit or replace a rules configuration file
<a name="AMP-rules-edit"></a>

If you want to change the rules in a rule file that you have already uploaded to Amazon Managed Service for Prometheus, you can either upload a new rules file to replace the existing configuration, or you can edit the current configuration directly in the console. Optionally, you can download the current file, edit it in a text editor, then upload the new version.

**To use the Amazon Managed Service for Prometheus console to edit your rules configuration**

1. Open the Amazon Managed Service for Prometheus console at [https://console.aws.amazon.com/prometheus/](https://console.aws.amazon.com/prometheus/home).

1. In the upper left corner of the page, choose the menu icon, and then choose **All workspaces**.

1. Choose the workspace ID of the workspace, and then choose the **Rules management** tab.

1. Select the name of the rules configuration file that you want to edit.

1. (Optional) If you want to download the current rules configuration file, choose **Download** or **Copy**.

1. Choose **Modify** to edit the configuration directly within the console. Choose **Save** when complete.

   Alternately, you can choose **Replace configuration** to upload a new configuration file. If so, select the new rules definition file, and choose **Continue** to upload it.

**To use the AWS CLI to edit a rules configuration file**

1. Base64 encode the contents of your rules file. On Linux, you can use the following command:

   ```
   base64 input-file output-file
   ```

   On macOS, you can use the following command:

   ```
   openssl base64 input-file output-file
   ```

1. Enter one of the following commands to upload the new file.

   On AWS CLI version 2, enter:

   ```
   aws amp put-rule-groups-namespace --data file://path_to_base_64_output_file --name namespace-name  --workspace-id my-workspace-id --region region
   ```

   On AWS CLI version 1, enter:

   ```
   aws amp put-rule-groups-namespace --data fileb://path_to_base_64_output_file --name namespace-name  --workspace-id my-workspace-id --region region
   ```

1. It takes a few seconds for your rules file to become active. To check the status, enter the following command:

   ```
   aws amp describe-rule-groups-namespace --workspace-id workspace_id --name namespace-name --region region
   ```

   If the `status` is `ACTIVE`, your rules file has taken effect. Until then, the previous version of this rules file is still active.
