# Setting the request list length for Decision Visualizer

In the PingAuthorize Policy Editor, you can select **Policies**, **Decision Visualizer**, and then **Recent Decisions** to view graphs of recent decisions, the times the requests were made, and the decision outcomes. The requests do not include test requests.

## About this task

The `RecentRequest.buffer.size` parameter in the configuration file determines the number of recent decisions to choose from. To configure the Policy Editor to use a different value for this parameter, re-run the `setup` tool using an options file to generate a new configuration, as shown in the following steps.

## Steps

1. Make a copy of the default options file.

   ### Example:

   ```shell
   $ cp config/options.yml my-options.yml
   ```

2. Edit the new options file and define `RecentRequest.buffer.size` in the `core` section.

   By default, the number of recent decisions is 20.

   |   |                                                                                  |
   | - | -------------------------------------------------------------------------------- |
   |   | Setting a buffer size greater than 20 can cause serious performance degradation. |

   To disable the feature, set the value to 0.

   ### Example:

   ```
   core:
     RecentRequest.buffer.size: 10
   # Other options omitted for brevity...
   ```

3. Stop the Policy Editor.

   ```shell
   $ bin/stop-server
   ```

4. Run `setup` using the `--optionsFile` argument, and then customize all other options as appropriate for your needs.

   ### Example:

   ```shell
   $ bin/setup demo \
    --adminUsername admin \
    --generateSelfSignedCertificate \
    --decisionPointSharedSecret <shared-secret> \
    --hostname <pap-hostname> \
    --port <pap-port> \
    --adminPort  <admin-port>  \
    --licenseKeyFile <path-to-license> \
    --optionsFile my-options.yml
   ```

5. Start the Policy Editor.

   ### Example:

   ```shell
   $ bin/start-server
   ```
