+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.

+%description
+collectd is a small daemon which collects system information periodically and
+provides mechanisms to monitor and store the values in a variety of ways. It
+is written in C for performance. Since the daemon doesn't need to startup
+every time it wants to update the values it's very fast and easy on the
+system. Also, the statistics are very fine grained since the files are updated
+every 10 seconds.

+B<Script> block, define arguments they will be merged by concatenating the
+arguments together in the order "NRPE-args Script-args".
+
+Please note that this option is rather dumb. It does not support "command
+argument processing" (i.e. replacing C<$ARG1$> and friends), inclusion of other
+NRPE config files, include directories etc.
+
=item B<Interval> I<Seconds>
Sets the interval in which the plugins are executed. This doesn't need to match
=item E<lt>B<Script> I<File>E<gt>
Adds a script to the list of scripts to be executed once per I<Interval>
-seconds. You can use the following optional arguments to specify the operation

+=head1 NAME
+
+collectd-threshold - Documentation of collectd's I<Threshold plugin>
+
+=head1 SYNOPSIS
+
+ LoadPlugin "threshold"
+ <Plugin "threshold">
+ <Type "foo">
+ WarningMin 0.00
+ WarningMax 1000.00
+ FailureMin 0.00
+ FailureMax 1200.00
+ Invert false
+ Instance "bar"
+ </Type>
+ </Plugin>
+
+=head1 DESCRIPTION
+
+Starting with version C<4.3.0> I<collectd> has support for B<monitoring>. By
+that we mean that the values are not only stored or sent somewhere, but that
+they are judged and, if a problem is recognized, acted upon. The only action
+the I<Threshold plugin> takes itself is to generate and dispatch a
+I<notification>. Other plugins can register to receive notifications and
+perform appropriate further actions.
+
+Since systems and what you expect them to do differ a lot, you can configure
+I<thresholds> for your values freely. This gives you a lot of flexibility but
+also a lot of responsibility.
+
+Every time a value is out of range, a notification is dispatched. This means
+that the idle percentage of your CPU needs to be less then the configured
+threshold only once for a notification to be generated. There's no such thing
+as a moving average or similar - at least not now.
+
+Also, all values that match a threshold are considered to be relevant or
+"interesting". As a consequence collectd will issue a notification if they are
+not received for B<Timeout> iterations. The B<Timeout> configuration option is
+explained in section L<collectd.conf(5)/"GLOBAL OPTIONS">. If, for example,
+B<Timeout> is set to "2" (the default) and some hosts sends it's CPU statistics
+to the server every 60 seconds, a notification will be dispatched after about
+120 seconds. It may take a little longer because the timeout is checked only
+once each B<Interval> on the server.
+
+When a value comes within range again or is received after it was missing, an
+"OKAY-notification" is dispatched.
+
+=head1 CONFIGURATION
+
+Here is a configuration example to get you started. Read below for more
+information.
+
+ LoadPlugin "threshold"
+ <Plugin "threshold">
+ <Type "foo">
+ WarningMin 0.00
+ WarningMax 1000.00
+ FailureMin 0.00
+ FailureMax 1200.00
+ Invert false
+ Instance "bar"
+ </Type>
+
+ <Plugin "interface">
+ Instance "eth0"
+ <Type "if_octets">
+ FailureMax 10000000
+ DataSource "rx"
+ </Type>
+ </Plugin>
+
+ <Host "hostname">
+ <Type "cpu">
+ Instance "idle"
+ FailureMin 10
+ </Type>
+
+ <Plugin "memory">
+ <Type "memory">
+ Instance "cached"
+ WarningMin 100000000
+ </Type>
+ </Plugin>
+
+ <Type "load">
+ DataSource "midterm"
+ FailureMax 4
+ Hits 3
+ Hysteresis 3
+ </Type>
+ </Host>
+ </Plugin>
+
+There are basically two types of configuration statements: The C<Host>,
+C<Plugin>, and C<Type> blocks select the value for which a threshold should be
+configured. The C<Plugin> and C<Type> blocks may be specified further using the
+C<Instance> option. You can combine the block by nesting the blocks, though
+they must be nested in the above order, i.e. C<Host> may contain either
+C<Plugin> and C<Type> blocks, C<Plugin> may only contain C<Type> blocks and
+C<Type> may not contain other blocks. If multiple blocks apply to the same
+value the most specific block is used.
+
+The other statements specify the threshold to configure. They B<must> be
+included in a C<Type> block. Currently the following statements are recognized:
+
+=over 4
+
+=item B<FailureMax> I<Value>
+
+=item B<WarningMax> I<Value>
+
+Sets the upper bound of acceptable values. If unset defaults to positive
+infinity. If a value is greater than B<FailureMax> a B<FAILURE> notification
+will be created. If the value is greater than B<WarningMax> but less than (or
+equal to) B<FailureMax> a B<WARNING> notification will be created.
+
+=item B<FailureMin> I<Value>
+
+=item B<WarningMin> I<Value>
+
+Sets the lower bound of acceptable values. If unset defaults to negative
+infinity. If a value is less than B<FailureMin> a B<FAILURE> notification will
+be created. If the value is less than B<WarningMin> but greater than (or equal
+to) B<FailureMin> a B<WARNING> notification will be created.
+
+=item B<DataSource> I<DSName>
+
+Some data sets have more than one "data source". Interesting examples are the
+C<if_octets> data set, which has received (C<rx>) and sent (C<tx>) bytes and
+the C<disk_ops> data set, which holds C<read> and C<write> operations. The
+system load data set, C<load>, even has three data sources: C<shortterm>,
+C<midterm>, and C<longterm>.
+
+Normally, all data sources are checked against a configured threshold. If this
+is undesirable, or if you want to specify different limits for each data
+source, you can use the B<DataSource> option to have a threshold apply only to
+one data source.
+
+=item B<Invert> B<true>|B<false>
+
+If set to B<true> the range of acceptable values is inverted, i.e. values
+between B<FailureMin> and B<FailureMax> (B<WarningMin> and B<WarningMax>) are
+not okay. Defaults to B<false>.
+
+=item B<Persist> B<true>|B<false>
+
+Sets how often notifications are generated. If set to B<true> one notification
+will be generated for each value that is out of the acceptable range. If set to
+B<false> (the default) then a notification is only generated if a value is out
+of range but the previous value was okay.
+
+This applies to missing values, too: If set to B<true> a notification about a
+missing value is generated once every B<Interval> seconds. If set to B<false>
+only one such notification is generated until the value appears again.
+
+=item B<PersistOK> B<true>|B<false>
+
+Sets how OKAY notifications act. If set to B<true> one notification will be
+generated for each value that is in the acceptable range. If set to B<false>
+(the default) then a notification is only generated if a value is in range but
+the previous value was not.
+
+=item B<Percentage> B<true>|B<false>
+
+If set to B<true>, the minimum and maximum values given are interpreted as
+percentage value, relative to the other data sources. This is helpful for
+example for the "df" type, where you may want to issue a warning when less than
+5E<nbsp>% of the total space is available. Defaults to B<false>.
+
+=item B<Hits> I<Value>
+
+Sets the number of occurrences which the threshold must be raised before to
+dispatch any notification or, in other words, the number of B<Interval>s
+that the threshold must be match before dispatch any notification.
+
+=item B<Hysteresis> I<Value>
+
+Sets the hysteresis value for threshold. The hysteresis is a method to prevent
+flapping between states, until a new received value for a previously matched
+threshold down below the threshold condition (B<WarningMax>, B<FailureMin> or
+everything else) minus the hysteresis value, the failure (respectively warning)
+state will be keep.
+
+=item B<Interesting> B<true>|B<false>
+
+If set to B<true> (the default), the threshold must be treated as interesting
+and, when a number of B<Timeout> values will lost, then a missing notification
+will be dispatched. On the other hand, if set to B<false>, the missing
+notification will never dispatched for this threshold.

+
+By default, this is disabled. As a special exception, if the plugin name is

+the average user from ever having to deal with this low level linking stuff.
+

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.

+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.

+This is useful when short bursts are not a problem. If, for example, 100% CPU

- libiptc (IPTables Chains) in collectd
-=======================================
-http://netfilter.org/
-http://collectd.org/
-
-About
------
-
- This is libiptc taken from the iptables source distribution. As it is not
- meant to be a public interface by upstream it is not shipped in some binary
- distributions. Thus, collectd ships its own copy as a fall-back.
-
- The presently available version was imported from iptables 1.4.1.1.
-
-Changes to the iptables upstream sources:
------------------------------------------
-
- * Added copyright headers mentioning the "Netfilter Core Team" as copyright
- holder.
-
- * Changed "libiptc/*" includes to "*".
-
- * Use the shipped copy of "xtables.h" instead of the one possibly available
- on the system.
