## Failover metrics for router inputs
<a name="monitor-with-cloudwatch-metrics-router-input-failover"></a>

When you configure a router input for failover, MediaConnect collects two sets of metrics: aggregate metrics for the overall router input, as well as source-level metrics to track the individual failover sources. 

### Aggregate failover metrics
<a name="cloudwatch-metrics-router-input-failover-aggregate"></a>

These metrics give you a view of the failover router input's performance.

## Merge metrics for router inputs
<a name="monitor-with-cloudwatch-metrics-router-input-merge"></a>
