#<Plugin aquaero>
global B<Interval> setting. If a plugin provides own support for specifying an
interval, that setting will take precedence.
+=item B<FlushInterval> I<Seconds>
+
+Specifies the the interval, in seconds, to call the flush callback if it's
+defined in this plugin. By default, this is disabled
+
+=item B<FlushTimeout> I<Seconds>
+
+Specifies the value of the timeout argument of the flush callback.
+
=back
=item B<AutoLoadPlugin> B<false>|B<true>
TCP-Port to connect to. Defaults to B<3551>.
-=item B<ReportSeconds> B<true|false>
+=item B<ReportSeconds> B<true>|B<false>
If set to B<true>, the time reported in the C<timeleft> metric will be
converted to seconds. This is the recommended setting. If set to B<false>, the
default for backwards compatibility, the time will be reported in minutes.
+=item B<PersistentConnection> B<true>|B<false>
+
+By default, the plugin will try to keep the connection to UPS open between
+reads. Since this appears to be somewhat brittle (I<apcupsd> appears to close
+the connection due to inactivity quite quickly), the plugin will try to detect
+this problem and switch to an open-read-close mode in such cases.
+
+You can instruct the plugin to close the connection after each read by setting
+this option to B<false>.
+
=back
=head2 Plugin C<aquaero>
Sets the URL to use to connect to the I<OpenLDAP> server. This option is
I<mandatory>.
+=item B<BindDN> I<BindDN>
+
+Name in the form of an LDAP distinguished name intended to be used for
+authentication. Defaults to empty string to establish an anonymous authorization.
+
+=item B<Password> I<Password>
+
+Password for simple bind authentication. If this option is not set,
+unauthenticated bind operation is used.
+
=item B<StartTLS> B<true|false>
Defines whether TLS must be used when connecting to the I<OpenLDAP> server.
allows to "group" several processes together. I<name> must not contain
slashes.
+=item B<CollectContextSwitch> I<Boolean>
+
+Collect context switch of the process.
