=head2 Plugin C<cpu>
-The I<CPU plugin> collects CPU usage metrics.
+The I<CPU plugin> collects CPU usage metrics. By default, CPU usage is reported
+as Jiffies, using the C<cpu> type. Two aggregations are available:
+
+=over 4
+
+=item
+
+Sum, per-state, over all CPUs installed in the system; and
+
+=item
+
+Sum, per-CPU, over all non-idle states of a CPU, creating an "active" state.
+
+=back
+
+The two aggregations can be combined, leading to I<collectd> only emitting a
+single "active" metric for the entire system. As soon as one of these
+aggregations (or both) is enabled, the I<cpu plugin> will report a percentage,
+rather than Jiffies. In addition, you can request individual, per-state,
+per-CPU metrics to be reported as percentage.
The following configuration options are available:
=over 4
-=item B<ReportActive> B<false>|B<true>
+=item B<ReportByState> B<true>|B<false>
-Reports non-idle CPU usage as the "active" value. Defaults to false.
+When set to B<true>, the default, reports per-state metrics, e.g. "system",
+"user" and "idle".
+When set to B<false>, aggregates (sums) all I<non-idle> states into one
+"active" metric.
-=item B<ReportByCpu> B<false>|B<true>
+=item B<ReportByCpu> B<true>|B<false>
-When true reports usage for all cores. When false, reports cpu usage
-aggregated over all cores.
-Defaults to true.
+When set to B<true>, the default, reports per-CPU (per-core) metrics.
+When set to B<false>, instead of reporting metrics for individual CPUs, only a
+global sum of CPU states is emitted.
=item B<ValuesPercentage> B<false>|B<true>
-When true report percentage usage instead of tick values. Defaults to false.
+This option is only considered when both, B<ReportByCpu> and B<ReportByState>
+are set to B<true>. In this case, by default, metrics will be reported as
+Jiffies. By setting this option to B<true>, you can request percentage values
+in the un-aggregated (per-CPU, per-state) mode as well.

=head2 Plugin C<cpufreq>
This plugin doesn't have any options. It reads
change, though this is unlikely. Oh, and if you want to help improving this
plugin, just send a short notice to the mailing list. ThanksE<nbsp>:)
+=head2 Plugin C<openldap>
+
+To use the C<openldap> plugin you first need to configure the I<OpenLDAP>
+server correctly. The backend database C<monitor> needs to be loaded and
+working. See slapd-monitor(5) for the details.
+
+The configuration of the C<openldap> plugin consists of one or more B<Instance>
+blocks. Each block requires one string argument as the instance name. For
+example:
+
+ <Plugin "openldap">
+ <Instance "foo">
+ URL "ldap://localhost/"
+ </Instance>
+ <Instance "bar">
+ URL "ldaps://localhost/"
+ </Instance>
+ </Plugin>
+
+The instance name will be used as the I<plugin instance>. To emulate the old
+(versionE<nbsp>4) behavior, you can use an empty string (""). In order for the
+plugin to work correctly, each instance name must be unique. This is not
+enforced by the plugin and it is your responsibility to ensure it is.
+
+The following options are accepted within each B<Instance> block:
+
+=over 4
+
+=item B<URL> I<ldap://host/binddn>
+
+Sets the URL to use to connect to the I<OpenLDAP> server. This option is
+I<mandatory>.
+
+=item B<StartTLS> B<true|false>
+
+Defines whether TLS must be used when connecting to the I<OpenLDAP> server.
+Disabled by default.
+
+=item B<VerifyHost> B<true|false>
+
+Enables or disables 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. Enabled by default.
+
+=item B<CACert> I<File>
+
+File that holds one or more SSL certificates. If you want to use TLS/SSL you
+may possibly need this option. What CA certificates are checked by default
+depends on the distribution you use and can be changed with the usual ldap
+client configuration mechanisms. See ldap.conf(5) for the details.
+
+=item B<Timeout> I<Seconds>
+
+Sets the timeout value for ldap operations. Defaults to B<-1> which results in
+an infinite timeout.
+
+=item B<Version> I<Version>
+
+An integer which sets the LDAP protocol version number to use when connecting
+to the I<OpenLDAP> server. Defaults to B<3> for using I<LDAPv3>.

=head2 Plugin C<openvpn>

+=head2 Plugin C<smart>
+
+The C<smart> plugin collects SMART information from physical
+disks. Values collectd include temperature, power cycle count, poweron
+time and bad sectors. Also, all SMART attributes are collected along
+with the normalized current value, the worst value, the threshold and
+a human readable value.
+
+Using the following two options you can ignore some disks or configure the
+collection only of specific disks.
+
+=over 4
+
+=item B<Disk> I<Name>
+
+Select the disk I<Name>. Whether it is collected or ignored depends on the
+B<IgnoreSelected> setting, see below. As with other plugins that use the
+daemon's ignorelist functionality, a string that starts and ends with a slash
+is interpreted as a regular expression. Examples:
+
+ Disk "sdd"
+ Disk "/hda[34]/"
+
+=item B<IgnoreSelected> B<true>|B<false>
+
+Sets whether selected disks, i.E<nbsp>e. the ones matches by any of the B<Disk>
+statements, are ignored or if all other disks are ignored. The behavior
+(hopefully) is intuitive: If no B<Disk> option is configured, all disks are
+collected. If at least one B<Disk> option is given and no B<IgnoreSelected> or
+set to B<false>, B<only> matching disks will be collected. If B<IgnoreSelected>
+is set to B<true>, all disks are collected B<except> the ones matched.

=head2 Plugin C<snmp>
Since the configuration of the C<snmp plugin> is a little more complicated than
how many connections a web proxy holds to web servers. You have to give the
port in numeric form.
+=item B<AllPortsSummary> I<true>|I<false>
+
+If this option is set to I<true> a summary of statistics from all connections
+are collectd. This option defaults to I<false>.
