 | <a name="input_logging_retention_in_days"></a> [logging\_retention\_in\_days](#input\_logging\_retention\_in\_days) | Specifies the number of days you want to retain log events for the lambda log group. Possible values are: 0, 1, 3, 5, 7, 14, 30, 60, 90, 120, 150, 180, 365, 400, 545, 731, 1827, and 3653. | `number` | `180` | no |
 | <a name="input_metrics_namespace"></a> [metrics\_namespace](#input\_metrics\_namespace) | The namespace for the metrics created by the module. Merics will only be created if explicit enabled. | `string` | `"GitHub Runners"` | no |
 | <a name="input_minimum_running_time_in_minutes"></a> [minimum\_running\_time\_in\_minutes](#input\_minimum\_running\_time\_in\_minutes) | The time an ec2 action runner should be running at minimum before terminated, if not busy. | `number` | `null` | no |
-| <a name="input_pool_config"></a> [pool\_config](#input\_pool\_config) | The configuration for updating the pool. The `pool_size` to adjust to by the events triggered by the `schedule_expression`. For example you can configure a cron expression for weekdays to adjust the pool to 10 and another expression for the weekend to adjust the pool to 1. | <pre>list(object({<br>    schedule_expression = string<br>    size                = number<br>  }))</pre> | `[]` | no |

You have the following options. 1. Disable by setting `enabled` to false. 2.
