The configuration consists of one or more EBEIE

+When I connects to a TSDB node, it will request the hostname from
+DNS. This can become a problem if the TSDB node is unavailable or badly
+configured because collectd will request DNS in order to reconnect for every
+metric, which can flood your DNS. So you can cache the last value for
+I seconds.
+Defaults to the I of the I, e.g. 10Eseconds.
+
+You can also define a jitter, a random interval to wait in addition to
+I. This prevents all your collectd servers to resolve the
+hostname at the same time when the connection fails.
+Defaults to the I of the I, e.g. 10Eseconds.
+
+B If the DNS resolution has already been successful when the socket
+closes, the plugin will try to reconnect immediately with the cached
+information. DNS is queried only when the socket is closed for a longer than
+I + I seconds.
