```
public Errors()
```
- Method Detail
  - getConnectionErrors
```
public com.codahale.metrics.Counter getConnectionErrors()
```
    Returns the number of errors while connecting to Cassandra nodes.
    This represents the number of times that a request to a Cassandra node has failed due to a connection problem. This thus also corresponds to how often the driver had to pick a fallback host for a request.
    You can expect a few connection errors when a Cassandra node fails (or is stopped) ,but if that number grows continuously you likely have a problem.
    
    Returns:
    
    the number of errors while connecting to Cassandra nodes.
