+2012-11-11, Version 5.1.1
+ * collectd: Create new directories with mode 0777 and let umask remove
+ unwanted permission bits.
+ * collectd: Build issues have been fixed.
+ * collectd: An incorrect assertion has been fixed in some common code
+ for Solaris. This should resolve pseudo-random assertion failures
+ under Solaris. Thanks to Jeff Blane for his help debugging this.
+ * collectd: A couple of memory leaks through PThread thread attributes
+ have been fixed. Thanks to Gerrie Roos for fixing these.
+ * collectdctl: Fix PUTVAL for data sets with multiple data sources.
+ Thanks to Cyril Feraudet for reporting this problem.
+ * contrib/migrate-4-5.px: Handle to "df" to "df_complex" conversion
+ correctly.
+ * apcups plugin: Improve the reconnect behavior.
+ * curl_xml plugin: The "Host" setting was silently ignored. Thanks to
+ Fabien Wernli for fixing this.
+ * df plugin: Ignore "rootfs" devices under Linux to avoid having them
+ reported twice. Thanks to Brune Prémont for fixing this.
+ * disk plugin: Fix incorrect computation of read and write latency (the
+ "disk_time" type). Previously, the numbers reported where too small
+ by a factor of "interval", e.g. when the interval is set to 10
+ seconds, the values were too low by a factor of 10. Thanks to Manuel
+ Sanmartin for reporting this problem.
+ * dns plugin: A build issue under Solaris has been fixed. A erroneous
+ define that could lead to the reporting of bad data has been fixed by
+ Daniel Sutto.
+ * ethstat plugin: An off-by-one error and potential use of
+ uninitialized memory has been fixed. Thanks to Mark Voelker for
+ reporting these problems.
+ * memcachec plugin: A bug in the configuration handling has been fixed.
+ Thanks to Pascal Hofmann for fixing this issue.
+ * mysql plugin: Fix a bug when registering multiple databases. Thanks
+ to Sebastian Harl for fixing this.
+ * netapp plugin: Correctly close the connection on communication
+ errors.
+ * netlink plugin: The function used to query statistics has been
+ changed to be more in line with iproute2's behavior. Thanks to
+ "KIvosak" for the patch.
+ * network plugin: Initialization of libgcrypt has been fixed. Thanks to
+ Chris Lundquist for his patch.
+ * oracle plugin: Error messages have been improved.
+ * ping plugin: Don't enter the exponential back-off mode when
+ ping_send() fails. This should make recovery after a network failure
+ much faster.
+ * python plugin: Memory leaks have been fixed. Thanks to Tommie Gannert
+ and Sven Trenkel for fixing this.
+ * redis plugin: Fix a compilation problem on FreeBSD. Thanks to
+ "biancalana" for the fix.
+ * rrdtool plugin: Fix an out-of-bounds array access when printing a
+ warning message. Thanks to Will Hawkins for fixing this bug.
+ * snmp plugin: Support for the SNMP_ENDOFMIBVIEW return value has been
+ added. Support for more complex / unusual MIBs / subtrees has been
+ added. Thanks to Mark Juric to test the changes and point out these
+ problems.
+ * varnish plugin: Support for multiple instances of Varnish 3 has been
+ fixed. Thanks to Jonathan Huot for the patch.
+ * write_mongodb plugin: Add compatibility with libmongo 0.6.0 and
+ later. Thanks to Chris Lundquist for this patch.
+
2012-04-01, Version 5.1.0
* Build system, iptables plugin: The shipped version of libiptc has
been removed.
* scale target: Support for scaling specific data sources only has been
added. Thanks to Gerrie Roos for his patch.

+=item B<Interval> I<Seconds>
+
+Sets a plugin-specific interval for collecting metrics. This overrides the
+global B<Interval> setting. If a plugin provides own support for specifying an
+interval, that setting will take precedence.
+
=back
=item B<Include> I<Path>

required C<mod_status> to be configured in the webserver you're going to
collect data from. These plugins are listed below as well, even if they don't

+require any configuration within collectd's configuration file.
A list of all plugins and a short summary for each plugin can be found in the
F<README> file shipped with the sourcecode and hopefully binary packets as
well.
+=head2 Plugin C<aggregation>
+
+The I<Aggregation plugin> makes it possible to aggregate several values into
+one using aggregation functions such as I<sum>, I<average>, I<min> and I<max>.
+This can be put to a wide variety of uses, e.g. average and total CPU
+statistics for your entire fleet.
+
+The grouping is powerful but, as with many powerful tools, may be a bit
+difficult to wrap your head around. The grouping will therefore be
+demonstrated using an example: The average and sum of the CPU usage across
+all CPUs of each host is to be calculated.
+
+To select all the affected values for our example, set C<Plugin cpu> and
+C<Type cpu>. The other values are left unspecified, meaning "all values". The
+I<Host>, I<Plugin>, I<PluginInstance>, I<Type> and I<TypeInstance> options
+work as if they were specified in the C<WHERE> clause of an C<SELECT> SQL
+statement.
+
+ Plugin "cpu"
+ Type "cpu"
+
+Although the I<Host>, I<PluginInstance> (CPU number, i.e. 0, 1, 2, ...) and
+I<TypeInstance> (idle, user, system, ...) fields are left unspecified in the
+example, the intention is to have a new value for each host / type instance
+pair. This is achieved by "grouping" the values using the C<GroupBy> option.
+It can be specified multiple times to group by more than one field.
+
+ GroupBy "Host"
+ GroupBy "TypeInstance"
+
+We do neither specify nor group by I<plugin instance> (the CPU number), so all
+metrics that differ in the CPU number only will be aggregated. Each
+aggregation needs I<at least one> such field, otherwise no aggregation would
+take place.
+
+The full example configuration looks like this:
+
+ <Plugin "aggregation">
+ <Aggregation>
+ Plugin "cpu"
+ Type "cpu"
+
+ GroupBy "Host"
+ GroupBy "TypeInstance"
+
+ CalculateSum true
+ CalculateAverage true
+ </Aggregation>
+ </Plugin>
+
+There are a couple of limitations you should be aware of:
+
+=over 4
+
+=item
+
+The I<Type> cannot be left unspecified, because it is not reasonable to add
+apples to oranges. Also, the internal lookup structure won't work if you try
+to group by type.
+
+=item
+
+There must be at least one unspecified, ungrouped field. Otherwise nothing
+will be aggregated.
+
+=back
+
+As you can see in the example above, each aggregation has its own
+B<Aggregation> block. You can have multiple aggregation blocks and aggregation
+blocks may match the same values, i.e. one value list can update multiple
+aggregations. The following options are valid inside B<Aggregation> blocks:
+
+=over 4
+
+=item B<Host> I<Host>
+
+=item B<Plugin> I<Plugin>
+
+=item B<PluginInstance> I<PluginInstance>
+
+=item B<Type> I<Type>
+
+=item B<TypeInstance> I<TypeInstance>
+
+Selects the value lists to be added to this aggregation. B<Type> must be a
+valid data set name, see L<types.db(5)> for details.
+
+=item B<GroupBy> B<Host>|B<Plugin>|B<PluginInstance>|B<TypeInstance>
+
+Group valued by the specified field. The B<GroupBy> option may be repeated to
+group by multiple fields.
+
+=item B<CalculateNum> B<true>|B<false>
+
+=item B<CalculateSum> B<true>|B<false>
+
+=item B<CalculateAverage> B<true>|B<false>
+
+=item B<CalculateMinimum> B<true>|B<false>
+
+=item B<CalculateMaximum> B<true>|B<false>
+
+=item B<CalculateStddev> B<true>|B<false>
+
+Boolean options for enabling calculation of the number of value lists, their
+sum, average, minimum, maximum andE<nbsp>/ or standard deviation. All options
+are disabled by default.
+
+=back
+
=head2 Plugin C<amqp>
The I<AMQMP plugin> can be used to communicate with other instances of
locally, or B<DataDir> is set to a relative path, this will not work as
expected. Default is B<true>.
+=item B<StepSize> I<Seconds>
+
+B<Force> the stepsize of newly created RRD-files. Ideally (and per default)
+this setting is unset and the stepsize is set to the interval in which the data
+is collected. Do not use this option unless you absolutely have to for some
+reason. Setting this option may cause problems with the C<snmp plugin>, the
+C<exec plugin> or when the daemon is set up to receive data from other hosts.
+
+=item B<HeartBeat> I<Seconds>
+
+B<Force> the heartbeat of newly created RRD-files. This setting should be unset
+in which case the heartbeat is set to twice the B<StepSize> which should equal
+the interval in which data is collected. Do not set this option unless you have
+a very good reason to do so.
+
+=item B<RRARows> I<NumRows>
+
+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
+B<MAX>. The five RRAs are optimized for graphs covering one hour, one day, one
+week, one month, and one year.
+
+So for each timespan, it calculates how many PDPs need to be consolidated into
+one CDP by calculating:
+ number of PDPs = timespan / (stepsize * rrarows)
+
+Bottom line is, set this no smaller than the width of you graphs in pixels. The
+default is 1200.
+
+=item B<RRATimespan> I<Seconds>
+
+Adds an RRA-timespan, given in seconds. Use this option multiple times to have
+more then one RRA. If this option is never used, the built-in default of (3600,
+86400, 604800, 2678400, 31622400) is used.
+
+For more information on how RRA-sizes are calculated see B<RRARows> above.
+
+=item B<XFF> I<Factor>
+
+Set the "XFiles Factor". The default is 0.1. If unsure, don't set this option.
+I<Factor> must be in the range C<[0.0-1.0)>, i.e. between zero (inclusive) and
+one (exclusive).
