# The cql-metrics-collector is connecting to Apache Cassandra using the

        #   keytool -import -alias CAroot -file ca.crt -keystore /etc/cql-metrics-collector/truststore.jks

    # Cassandra node metrics should be collected from. This can be set by IP
    # address and port, or by hostname and port. However, if you want to connect
    # to Cassandra encrypted, the hostname might be set matching to the subject
    # or one of the SANs of the certificate the Cassandra node is using.
    #
    # If not set, the collector will try to connect to the local Cassandra node
    # on port 9042 and by obtaining the local hostname using Java API 
    # java.net.Inet4Address.getLocalHost().getCanonicalHostName().
    // node = "127.0.0.1:9042"

    # local Cassandra node.
