public com.codahale.metrics.Counter getConnectionErrors()
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.
