- perl
The perl plugin implements a Perl-interpreter into collectd. You can
write your own plugins in Perl and return arbitrary values using this
needed. Please read collectd-unixsock(5) for a description on how that's
done.
- * Filtering and rewriting values dispatched to collectd can be done by the
- following plugins:
-
- - filter_pcre
- Filter and rewrite value lists based on Perl-compatible regular
- expressions.
-
* Logging is, as everything in collectd, provided by plugins. The following
plugins keep up informed about what's going on:
Notifications are propagated to plugins written in Perl as well.
See collectd-perl(5).
+ * Value processing can be controlled using the "filter chain" infrastructure
+ and "matches" and "targets". The following plugins are available:
+
+ - match_regex
+ Match values by their identifier based on regular expressions.
+
+ - match_timediff
+ Match values with an invalid timestamp.
+
+ - match_value
+ Select values by their data sources' values.
+
+ - target_notification
+ Create and dispatch a notification.
+
+ - target_replace
+ Replace parts of an identifier using regular expressions.
+
+ - target_set
+ Set (overwrite) entire parts of an identifier.
+
* Miscellaneous plugins:
- uuid
particular.
<http://developer.apple.com/corefoundation/>
+ * libclntsh (optional)
+ Used by the `oracle' plugin.
+
* libcurl (optional)
- If you want to use the `apache', `ascent', or `nginx' plugin.

* libdbi (optional)
Used to capture packets by the `dns' plugin.

- * libpcre (optional)

* libperl (optional)
Obviously used by the `perl' plugin. The library has to be compiled with
ithread support (introduced in Perl 5.6.0).

-=head2 Plugin C<filter_pcre>
-
-This plugin allows you to filter and rewrite value lists based on
-Perl-compatible regular expressions whose syntax and semantics are as close as
-possible to those of the Perl 5 language. See L<pcre(3)> for details.
-
- <Plugin filter_pcre>
- <RegEx>
- Host "^mail\d+$"
- Plugin "^tcpconns$"
- TypeInstance "^SYN_"
-
- Action NoWrite
- </RegEx>
-
- <RegEx>
- Plugin "^sensors$"
- PluginInstance "^Some Weird Sensor Chip Name Prefix"
-
- SubstitutePluginInstance "foo"
- </RegEx>
- </Plugin>
-
-The configuration consists of one or more C<RegEx> blocks, each of which
-specifies a regular expression identifying a set of value lists and how to
-handle successful matches. A value list keeps the values of a single data-set
-and is identified by the tuple (host, plugin, plugin instance, type, type
-instance). The plugin and type instances are optional components. If they are
-missing they are treated as empty strings. Within those blocks, the following
-options are recognized:
-
-=over 4
-
-=item B<Host> I<regex>
-
-=item B<Plugin> I<regex>
-
-=item B<PluginInstance> I<regex>
-
-=item B<Type> I<regex>
-
-=item B<TypeInstance> I<regex>
-
-Specifies the regular expression for each component of the identifier. If any
-of these options is missing it is interpreted as a pattern which matches any
-string. All five components of a value list have to match the appropriate
-regular expression to trigger the specified action.
-
-=item B<Action> I<NoWrite>|I<NoThresholdCheck>|I<Ignore>
-
-Specify how to handle successful matches:
-
-=over 4
-
-=item B<NoWrite>
-
-Do not send the value list to any output (a.k.a. write) plugins.
-
-=item B<NoThresholdCheck>
-
-Skip threshold checking for this value list.
-
-=item B<Ignore>
-
-Completely ignore this value list.
-
-=back
-
-Two or more actions may be combined by specifying multiple B<Action> options.
-
-=item B<SubstituteHost> I<replacement>
-
-=item B<SubstitutePlugin> I<replacement>
-
-=item B<SubstitutePluginInstance> I<replacement>
-
-=item B<SubstituteType> I<replacement>
-
-=item B<SubstituteTypeInstance> I<replacement>
-
-Upon a successful match, the matching substring will be replaced by the
-specified I<replacement> text. These options require that an appropriate regex
-has been specified before, e.E<nbsp>g. B<SubstituteHost> requires that the
-B<Host> option has been specified before.
-
-B<Note>: It is not recommended to modify the type unless you really know what
-you are doing. The type is used to identify the data-set definition of the
-dispatched values.
