# Define a resolver to be used when servers are specified by name and
# therefore requires name resolution. Server name resolution typically
# occurs only at startup. With this configuration, name resolution
# will occur once every 10s. Successful name resolution results in the
# server being marked UP while failure results in the server being
# marked DOWN. Note this only occurs when servers are specified by
# name.
