and are checked by default depends on the distribution you use.
+=item B<Header> I<Header>
+
+A HTTP header to add to the request. Multiple headers are added if this option
+is specified more than once.
+
+=item B<Post> I<Body>
+
+Specifies that the HTTP operation should be a POST instead of a GET. The
+complete data to be posted is given as the argument. This option will usually
+need to be accompanied by a B<Header> option to set an appropriate
+C<Content-Type> for the post body (e.g. to
+C<application/x-www-form-urlencoded>).
+
=item B<MeasureResponseTime> B<true>|B<false>
Measure response time for the request. If this setting is enabled, B<Match>
Sets the plugin instance to I<Instance>.
=item B<User> I<Name>
-
-Username to use if authorization is required to read the page.
-
=item B<Password> I<Password>
-
-Password to use if authorization is required to read the page.
-
=item B<VerifyPeer> B<true>|B<false>
-
-Enable or disable peer SSL certificate verification. See
-L<http://curl.haxx.se/docs/sslcerts.html> for details. Enabled by default.
-
=item B<VerifyHost> B<true>|B<false>
-
-Enable or disable peer host name verification. If enabled, the plugin checks if
-the C<Common Name> or a C<Subject Alternate Name> field of the SSL certificate
-matches the host name provided by the B<URL> option. If this identity check
-fails, the connection is aborted. Obviously, only works when connecting to a
-SSL enabled server. Enabled by default.
-
=item B<CACert> I<file>
+=item B<Header> I<Header>
+=item B<Post> I<Body>
-File that holds one or more SSL certificates. If you want to use HTTPS you will
-possibly need this option. What CA certificates come bundled with C<libcurl>
-and are checked by default depends on the distribution you use.
+These options behave exactly equivalent to the appropriate options of the
+I<cURL> plugin. Please see there for a detailed description.
=back
Use I<Instance> as the plugin instance when submitting values. Defaults to an
empty string (no plugin instance).
+=item B<Namespaces> I<Prefix> I<URL>
+
+If an XPath expression references namespaces, they must be specified
+with this option. I<Prefix> is the "namespace prefix" used in the XML document.
+I<URL> is the "namespace name", an URI reference uniquely identifying the
+namespace. The option can be repeated to register multiple namespaces.
+
+Examples:
+
+ Namespace "s" "http://schemas.xmlsoap.org/soap/envelope/"
+ Namespace "m" "http://www.w3.org/1998/Math/MathML"

locally, or B<DataDir> is set to a relative path, this will not work as
expected. Default is B<true>.
+=item B<CreateFilesAsync> B<false>|B<true>
+
+When enabled, new RRD files are enabled asynchronously, using a separate thread
+that runs in the background. This prevents writes to block, which is a problem
+especially when many hundreds of files need to be created at once. However,
+since the purpose of creating the files asynchronously is I<not> to block until
+the file is available, values before the file is available will be discarded.
+When disabled (the default) files are created synchronously, blocking for a
+short while, while the file is being written.
+
=item B<StepSize> I<Seconds>
B<Force> the stepsize of newly created RRD-files. Ideally (and per default)

The C<rrdtool plugin> calculates the number of PDPs per CDP based on the
B<StepSize>, this setting and a timespan. This plugin creates RRD-files with
-three times five RRAs, i.
e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
+three times five RRAs, i.e. five RRAs with the CFs B<MIN>, B<AVERAGE>, and
B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
week, one month, and one year.
