 +=head2 Plugin C<tcpconns>
 +
 +The C<tcpconns plugin> counts the number of currently established TCP
 +connections based on the local port and/or the remote port. Since there may be
 +a lot of connections the default if to count all connections with a local port,
 +for which a listening socket is opened. You can use the following options to
 +fine-tune the ports you are interested in:
 +
 +=over 4
 +
 +=item B<ListeningPorts> I<true>|I<false>
 +
 +If this option is set to I<true>, statistics for all local ports for which a
 +listening socket exists are collected. The default depends on B<LocalPort> and
 +B<RemotePort> (see below): If no port at all is specifically selected, the
 +default is to collect listening ports. If specific ports (no matter if local or
 +remote ports) are selected, this option defaults to I<false>, i.E<nbsp>e. only
 +the selected ports will be collected unless this option is set to I<true>
 +specifically.
 +
 +=item B<LocalPort> I<Port>
 +
 +Count the connections to a specific local port. This can be used to see how
 +many connections are handled by a specific daemon, e.E<nbsp>g. the mailserver.
 +You have to specify the port in numeric form, so for the mailserver example
 +you'd need to set B<25>.
 +
 +=item B<RemotePort> I<Port>
 +
 +Count the connections to a specific remote port. This is useful to see how
 +much a remote service is used. This is most useful if you want to know how many
 +connections a local service has opened to remote services, e.E<nbsp>g. how many
 +connections a mail server or news server has to other mail or news servers, or
 +how many connections a web proxy holds to web servers. You have to give the
 +port in numeric form.
