## Configuration

Available when configuring a failover collector are the following fieldsets:

### Main collector

**Description:** Select the main collector for which you want the collector to be the failover. Only collectors of the same type can be selected.

### Port

**Description:** This is the port the main collector will listen on to serve the health status to the failover collector. Enter a tcp port number above 1023 and at most 65353; values outside that range are rejected. Make sure your firewall configuration allows a connection on this port from the host on which the failover collector is running to the host on which the main collector is running.

### Host

**Description:** This is the host address to which the failover collector will try to connect to get the health status of the main collector. This can be an ip address or a resolvable hostname.

### Timeout

**Description:** This is the number of seconds the failover collector will wait before becoming “active” after it has deemed the main collector to be unhealthy.

### Stop delay

**Description:** This is the number of seconds the failover collector will wait before returning to the “idle” state after it deemed the main collector to be healthy.
