You can use a MirrorMaker2 Heartbeat connector to generate heartbeat messages to a local cluster’s `heartbeat` topic.

There are no prerequisites or limitations associated with this connector.

## [](#create-a-mirrormaker2-heartbeat-connector)Create a MirrorMaker2 Heartbeat connector

To create the MirrorMaker2 Heartbeat connector:

1.  In Redpanda Cloud, click **Connectors** in the navigation menu, and then click **Create Connector**.

2.  Select **Import from Heartbeat**.

3.  On the **Create Connector** page, specify the following required connector configuration options:

    | Property name | Property key | Description |
    | --- | --- | --- |
    | Emit heartbeats interval seconds | emit.heartbeats.interval.seconds | Frequency of heartbeats. The default is 1. |
    | Connector name | name | Globally-unique name to use for this connector. |

4.  Click **Next**. Review the connector properties specified, then click **Create**.


### [](#advanced-mirrormaker2-heartbeat-connector-configuration)Advanced MirrorMaker2 Heartbeat connector configuration

In most instances, the preceding basic configuration properties are sufficient. If you require additional property settings, then specify any of the following _optional_ advanced connector configuration properties by selecting **Show advanced options** on the **Create Connector** page:

| Property name | Property key | Description |
| --- | --- | --- |
| Source cluster alias | source.cluster.alias | Used to generate the heartbeat topic key. The default is source. |
| Target cluster alias | target.cluster.alias | Used to generate the heartbeat topic key. The default is target. |
| Heartbeats topic replication factor | heartbeats.topic.replication.factor | Replication factor for heartbeats topic. The default is -1. |

## [](#test-the-connection)Test the connection

After the connector is created, check to ensure that:

-   There are no errors in logs and in Redpanda Console.

-   Check to confirm the `heartbeat` topic has heartbeat messages.
