+ </Plugin>
+
+=head1 DESCRIPTION
+
+The I<Java> plugin embeds a I<Java Virtual Machine> (JVM) into I<collectd> and
+provides a Java interface to part of collectd's API. This makes it possible to
+write additions to the daemon in Java.
+
+This plugin is similar in nature to, but shares no code with, the I<Perl>
+plugin by Sebastian Harl, see L<collectd-perl(5)> for details.
+
+=head1 CONFIGURATION
+
+A short outline of this plugin's configuration can be seen in L<"SYNOPSIS">
+above. For a complete list of all configuration options and their semantics
+please read L<collectd.conf(5)/Plugin C<java>>.
+
+=head1 OVERVIEW
+
+When writing additions for collectd in Java, the underlying C base is mostly
+hidden from you. All complex data types are converted to their Java counterparts
+before they're passed to your functions. These Java classes reside in the
+I<org.collectd.api> namespace.
+
+The I<Java> plugin will create one object of each class configured with the
+B<LoadPlugin> option. The constructor of this class can then register "callback
+methods", i.E<nbsp>e. methods that will be called by the daemon when
+appropriate.
+
+The available classes are:
+
+=over 4
+
+=item B<org.collectd.api.Collectd>
+
+All API functions exported to Java are implemented as static functions of this
+class. See L<"EXPORTED API FUNCTIONS"> below.
+
+=item B<org.collectd.api.OConfigValue>
+
+Corresponds to C<oconfig_value_t>, defined in F<src/liboconfig/oconfig.h>.
+
+=item B<org.collectd.api.OConfigItem>
+
+Corresponds to C<oconfig_item_t>, defined in F<src/liboconfig/oconfig.h>.
+
+=item B<org.collectd.api.DataSource>
+
+Corresponds to C<data_source_t>, defined in F<src/plugin.h>.
+
+=item B<org.collectd.api.DataSet>
+
+Corresponds to C<data_set_t>, defined in F<src/plugin.h>.
+
+=item B<org.collectd.api.ValueList>
+
+Corresponds to C<value_list_t>, defined in F<src/plugin.h>.
+
+=item B<org.collectd.api.Notification>
+
+Corresponds to C<notification_t>, defined in F<src/plugin.h>.
+
+=back
+
+In the remainder of this document, we'll use the short form of these names, for
+example B<ValueList>. In order to be able to use these abbreviated names, you
+need to B<import> the classes.
+
+=head1 EXPORTED API FUNCTIONS
+
+All collectd API functions that are available to Java plugins are implemented
+as I<publicE<nbsp>static> functions of the B<Collectd> class. This makes
+calling these functions pretty straight forward. For example, to send an error
+message to the daemon, you'd do something like this:
+
+ Collectd.logError ("That wasn't chicken!");
+
+The following are the currently exported functions.
+
+=head2 registerConfig
+
+Signature: I<int> B<registerConfig> (I<String> name,
+I<CollectdConfigInterface> object);
+
+Registers the B<config> function of I<object> with the daemon.
+
+Returns zero upon success and non-zero when an error occurred.
+
+See L<"config callback"> below.
+
+=head2 registerInit
+
+Signature: I<int> B<registerInit> (I<String> name,
+I<CollectdInitInterface> object);
+
+Registers the B<init> function of I<object> with the daemon.
+
+Returns zero upon success and non-zero when an error occurred.

+
+=head2 registerFlush
+
+Signature: I<int> B<registerFlush> (I<String> name,
+I<CollectdFlushInterface> object)
+
+Registers the B<flush> function of I<object> with the daemon.
+
+Returns zero upon success and non-zero when an error occurred.
+

+=head2 registerShutdown
+
+Signature: I<int> B<registerShutdown> (I<String> name,

+
+Returns zero upon success and non-zero when an error occurred.
+
+See L<"shutdown callback"> below.
+
+=head2 registerLog
+
+Signature: I<int> B<registerLog> (I<String> name,
+I<CollectdLogInterface> object);
+

+
+=head2 registerMatch
+
+Signature: I<int> B<registerMatch> (I<String> name,
+I<CollectdMatchFactoryInterface> object);
+
+Registers the B<createMatch> function of I<object> with the daemon.

+
+Passes the values represented by the B<ValueList> object to the
+C<plugin_dispatch_values> function of the daemon. The "data set" (or list of
+"data sources") associated with the object are ignored, because
+C<plugin_dispatch_values> will automatically lookup the required data set. It
+is therefore absolutely okay to leave this blank.
+
+Returns zero upon success or non-zero upon failure.
+
+=head2 getDS
+
+Signature: I<DataSet> B<getDS> (I<String>)

+
+=head2 logInfo
+
+Signature: I<void> B<logInfo> (I<String>)
+
+Sends a log message with severity B<INFO> to the daemon.
+
+=head2 logDebug
+
+Signature: I<void> B<logDebug> (I<String>)
+
+Sends a log message with severity B<DEBUG> to the daemon.
+
+=head1 REGISTERING CALLBACKS
+
+When starting up, collectd creates an object of each configured class. The
+constructor of this class should then register "callbacks" with the daemon,
+using the appropriate static functions in B<Collectd>,
+see L<"EXPORTED API FUNCTIONS"> above. To register a callback, the object being
+passed to one of the register functions must implement an appropriate
+interface, which are all in the B<org.collectd.api> namespace.
+
+A constructor may register any number of these callbacks, even none. An object
+without callback methods is never actively called by collectd, but may still
+call the exported API functions. One could, for example, start a new thread in
+the constructor and dispatch (submit to the daemon) values asynchronously,
+whenever one is available.
+
+Each callback method is now explained in more detail:
+
+=head2 config callback
+
+Interface: B<org.collectd.api.CollectdConfigInterface>
+
+Signature: I<int> B<config> (I<OConfigItem> ci)
+
+This method is passed a B<OConfigItem> object, if both, method and
+configuration, are available. B<OConfigItem> is the root of a tree representing
+the configuration for this plugin. The root itself is the representation of the
+B<E<lt>PluginE<nbsp>/E<gt>> block, so in next to all cases the children of the
+root are the first interesting objects.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+
+See L<"registerConfig"> above.
+
+=head2 init callback
+
+Interface: B<org.collectd.api.CollectdInitInterface>
+
+Signature: I<int> B<init> ()
+
+This method is called after the configuration has been handled. It is
+supposed to set up the plugin. e.E<nbsp>g. start threads, open connections, or
+check if can do anything useful at all.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and the plugin will be disabled entirely.
+
+See L<"registerInit"> above.
+
+=head2 read callback
+
+Interface: B<org.collectd.api.CollectdReadInterface>
+
+Signature: I<int> B<read> ()
+
+This method is called periodically and is supposed to gather statistics in
+whatever fashion. These statistics are represented as a B<ValueList> object and
+sent to the daemon using L<dispatchValues|"dispatchValues">.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+Currently, returning non-zero does not have any other effects. In particular,
+Java "read"-methods are not suspended for increasing intervals like C
+"read"-functions.
+
+See L<"registerRead"> above.
+
+=head2 write callback
+
+Interface: B<org.collectd.api.CollectdWriteInterface>
+
+Signature: I<int> B<write> (I<ValueList> vl)
+
+This method is called whenever a value is dispatched to the daemon. The
+corresponding C "write"-functions are passed a C<data_set_t>, so they can
+decide which values are absolute values (gauge) and which are counter values.
+To get the corresponding C<ListE<lt>DataSourceE<gt>>, call the B<getDataSource>
+method of the B<ValueList> object.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerWrite"> above.
+
+=head2 flush callback
+
+Interface: B<org.collectd.api.CollectdFlushInterface>
+
+Signature: I<int> B<flush> (I<int> timeout, I<String> identifier)
+
+This method is called when the daemon received a flush command. This can either
+be done using the C<USR1> signal (see L<collectd(1)>) or using the I<unixsock>
+plugin (see L<collectd-unixsock(5)>).
+
+If I<timeout> is greater than zero, only values older than this number of
+seconds should be flushed. To signal that all values should be flushed
+regardless of age, this argument is set to a negative number.
+
+The I<identifier> specifies which value should be flushed. If it is not
+possible to flush one specific value, flush all values. To signal that all
+values should be flushed, this argument is set to I<null>.
+
+To signal success, this method has to return zero. Anything else will be
+considered an error condition and cause an appropriate message to be logged.
+
+See L<"registerFlush"> above.
+
+=head2 shutdown callback
+
+Interface: B<org.collectd.api.CollectdShutdownInterface>
+
+Signature: I<int> B<shutdown> ()
+
+This method is called when the daemon is shutting down. You should not rely on
+the destructor to clean up behind the object but use this function instead.
+

+L<collectd-java(5)>.
+
+Synopsis:
+
+ <Plugin "java">
+ JVMArg "-verbose:jni"

+ LoadPlugin "org.collectd.java.Foobar"
+ <Plugin "org.collectd.java.Foobar">
+ # To be parsed by the plugin
+ </Plugin>
+ </Plugin>
+
+Available configuration options:
+
+=over 4
+
+=item B<JVMArg> I<Argument>
+
+Argument that is to be passed to the I<Java Virtual Machine> (JVM). This works
+exactly the way the arguments to the I<java> binary on the command line work.
+Execute C<javaE<nbsp>--help> for details.
+
+Please note that B<all> these options must appear B<before> (i.E<nbsp>e. above)
+any other options! When another option is found, the JVM will be started and
+later options will have to be ignored!
+
+=item B<LoadPlugin> I<JavaClass>
+
+Instantiates a new I<JavaClass> object. The constructor of this object very
+likely then registers one or more callback methods with the server.
+
+See L<collectd-java(5)> for details.
+
+When the first such option is found, the virtual machine (JVM) is created. This
+means that all B<JVMArg> options must appear before (i.E<nbsp>e. above) all
+B<LoadPlugin> options!
+
+=item B<Plugin> I<Name>
+
+The entire block is passed to the Java plugin as an
+I<org.collectd.api.OConfigItem> object.
+
+For this to work, the plugin has to register a configuration callback first,
+see L<collectd-java(5)/"config callback">. This means, that the B<Plugin> block
+must appear after the appropriate B<LoadPlugin> block. Also note, that I<Name>
+depends on the (Java) plugin registering the callback and is completely
+independent from the I<JavaClass> argument passed to B<LoadPlugin>.

=head2 Plugin C<libvirt>
This plugin allows CPU, disk and network load to be collected for virtualized
=head2 Plugin C<ping>
+The I<Ping> plugin starts a new thread which sends ICMP "ping" packets to the
+configured hosts periodically and measures the network latency. Whenever the
+C<read> function of the plugin is called, it submits the average latency, the
+standard deviation and the drop rate for each host.
+
+Available configuration options:
+
=over 4
=item B<Host> I<IP-address>
Host to ping periodically. This option may be repeated several times to ping
multiple hosts.
+=item B<Interval> I<Seconds>
+
+Sets the interval in which to send ICMP echo packets to the configured hosts.
+This is B<not> the interval in which statistics are queries from the plugin but
+the interval in which the hosts are "pinged". Therefore, the setting here
+should be smaller than or equal to the global B<Interval> setting. Fractional
+times, such as "1.24" are allowed.
+
+Default: B<1.0>
+
+=item B<Timeout> I<Seconds>
+
+Time to wait for a response from the host to which an ICMP packet had been
+sent. If a reply was not received after I<Seconds> seconds, the host is assumed
+to be down or the packet to be dropped. This setting must be smaller than the
+B<Interval> setting above for the plugin to work correctly. Fractional
+arguments are accepted.
+
+Default: B<0.9>
+
=item B<TTL> I<0-255>
Sets the Time-To-Live of generated ICMP packets.
=back
+=head2 Plugin C<protocols>
+
+Collects a lot of information about various network protocols, such as I<IP>,
+I<TCP>, I<UDP>, etc.
+
+Available configuration options:
+
+=over 4
+
+=item B<Value> I<Selector>
+
+Selects whether or not to select a specific value. The string being matched is
+of the form "I<Protocol>:I<ValueName>", where I<Protocol> will be used as the
+plugin instance and I<ValueName> will be used as type instance. An example of
+the string being used would be C<Tcp:RetransSegs>.
+
+You can use regular expressions to match a large number of values with just one
+configuration option. To select all "extended" I<TCP> values, you could use the
+following statement:
+
+ Value "/^TcpExt:/"
+
+Whether only matched values are selected or all matched values are ignored
+depends on the B<IgnoreSelected>. By default, only matched values are selected.
+If no value is configured at all, all values will be selected.
+
+=item B<IgnoreSelected> B<true>|B<false>
+
+If set to B<true>, inverts the selection made by B<Value>, i.E<nbsp>e. all
+matching values will be ignored.

+example, this plugin may be used to get values from the Linux L<proc(5)>
+filesystem or CSV (comma separated values) files.
+
+ <Plugin table>
+ <Table "/proc/slabinfo">
+ Instance "slabinfo"
+ Separator " "
+ <Result>
+ Type gauge
+ InstancePrefix "active_objs"
+ InstancesFrom 0
+ ValuesFrom 1
+ </Result>
+ <Result>
+ Type gauge
+ InstancePrefix "objperslab"
+ InstancesFrom 0
+ ValuesFrom 4
+ </Result>
+ </Table>
+ </Plugin>
+
+The configuration consists of one or more B<Table> blocks, each of which
+configures one file to parse. Within each B<Table> block, there are one or
+more B<Result> blocks, which configure which data to select and how to
+interpret it.
+
+The following options are available inside a B<Table> block:
+
+=over 4
+
+=item B<Instance> I<instance>
+
+If specified, I<instance> is used as the plugin instance. So, in the above
+example, the plugin name C<table-slabinfo> would be used. If omitted, the
+filename of the table is used instead, with all special characters replaced
+with an underscore (C<_>).
+
+=item B<Separator> I<string>
+
+Any character of I<string> is interpreted as a delimiter between the different
+columns of the table. A sequence of two or more contiguous delimiters in the
+table is considered to be a single delimiter, i.E<nbsp>e. there cannot be any
+empty columns. The plugin uses the L<strtok_r(3)> function to parse the lines
+of a table - see its documentation for more details. This option is mandatory.
+
+A horizontal tab, newline and carriage return may be specified by C<\\t>,
+C<\\n> and C<\\r> respectively. Please note that the double backslashes are
+required because of collectd's config parsing.
+
+=back
+
+The following options are available inside a B<Result> block:
+
+=over 4
+
+=item B<Type> I<type>
+
+Sets the type used to dispatch the values to the daemon. Detailed information
+about types and their configuration can be found in L<types.db(5)>. This
+option is mandatory.
+
+=item B<InstancePrefix> I<prefix>
+
+If specified, prepend I<prefix> to the type instance. If omitted, only the
+B<InstancesFrom> option is considered for the type instance.
+
+=item B<InstancesFrom> I<column0> [I<column1> ...]
+
+If specified, the content of the given columns (identified by the column
+number starting at zero) will be used to create the type instance for each
+row. Multiple values (and the instance prefix) will be joined together with
+dashes (I<->) as separation character. If omitted, only the B<InstancePrefix>
+option is considered for the type instance.
+
+The plugin itself does not check whether or not all built instances are
+different. It’s your responsibility to assure that each is unique. This is
+especially true, if you do not specify B<InstancesFrom>: B<You> have to make
+sure that the table only contains one row.
+
+If neither B<InstancePrefix> nor B<InstancesFrom> is given, the type instance
+will be empty.
+
+=item B<ValuesFrom> I<column0> [I<column1> ...]
+
+Specifies the columns (identified by the column numbers starting at zero)
+whose content is used as the actual data for the data sets that are dispatched
+to the daemon. How many such columns you need is determined by the B<Type>
+setting above. If you specify too many or not enough columns, the plugin will
+complain about that and no data will be submitted to the daemon. The plugin
+uses L<strtoll(3)> and L<strtod(3)> to parse counter and gauge values
+respectively, so anything supported by those functions is supported by the
+plugin as well. This option is mandatory.
