# Rooms ![Configuring rooms in the Developer Portal](https://4229720839-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FdBiAEtFeZKdAwRyJ9MEL%2Fuploads%2FUQuT1UP9n9ZwF9737HKT%2Fimage.png?alt=media) From the left sidebar, select *Rooms*. On this page you can: * choose the regions you want to allow your rooms to be created in * enable Simulators for your Rooms * view a list of recently created Rooms * view a list of recently uploaded Simulators ### Simulators From the Developer Portal, you can configure what size you want your Simulator instances to be. To attach a Simulator to a Room, send the "Simulator slug" uploaded through the SDK with the Rooms creation request. When using the [PlayResolver](https://docs.coherence.io/0.10/coherence-api/rooms#rooms-api) to create Rooms, the Simulator uploaded through the SDK is automatically assigned in the creation request.
### Replication Server & Send Frequency The packet frequencies for sending and receiving data can be adjusted per project. It is part of the *Advanced Config* section and adjusting the frequencies is available only for paid plans.
### Recent Rooms Table The Recent Rooms Table provide a quick view of the recently created Rooms with the following information per column: | Column name | Description | | ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **ID** | ID of the Room. | | **KV** | Key-value pairs associated with the Room. | | **Tags** | Tags attached to the Room. | | **SDK** | SDK version used by the Room. | | **Sim** | Sim Slug for the Room. | | **Schema** | Schema ID used by the Room. | | **IP** | IP address of the Replication Server attached to the Room. | | **Created** | Time duration since the Room creation. | | **Room** **Status** | Status of the Room (Open or Closed). | | **Sim Status** | Status of the Simulator attached to the Room (Starting, Started, Stopped). | | **Messages** |

Messages from the Simulator orchestration.
This field is usually empty but will contain a message if an issue happened with the Simulator life-cycle. The message provides the reason for the Simulator's current state (usually Stopped).
Once a Simulator is stopped (for Room inactivity for instance), the Message column will mention Idle-stopped.
