# UpdateRealtimeLogConfig
<a name="API_UpdateRealtimeLogConfig"></a>

1. Call `GetRealtimeLogConfig` to get the current real-time log configuration.

1. Locally modify the parameters in the real-time log configuration that you want to update.

1. Call this API (`UpdateRealtimeLogConfig`) by providing the entire real-time log configuration, including the parameters that you modified and those that you didn't.

You cannot update a real-time log configuration's `Name` or `ARN`.
