interesting. Please note that no sanity- checking whatsoever is performed. You
can seriously fuck up your RRD files if you don't know what you're doing.
`/var/lib/collectd/' and generate an HTML file and a directory containing
several PNG files which are graphs of the RRD files found.
-collectd.conf
+collection.cgi
+--------------
+ Sample CGI script that creates graphs on the fly. The Perl modules `RRDs'
+(Debian package `librrds-perl'), `URI:Escape' (package liburi-perl),
+`HTML::Entities' (package libhtml-parser-perl) and a CGI capable web server
+(e.g. apache2 or boa) are needed. Simply install the script to a place where
+the webserver will treat it as a CGI script (/usr/lib/cgi-bin/ by default) and
+visit that page in a browser (http://localhost/cgi-bin/collection.cgi by
+default). Please refer to your webserver's documentation for more details.
+
+ Starting with version 4, collection.cgi requires a small config file, which
+should look something like this:
+
+ datadir: "/var/lib/collectd/rrd/"
+ libdir: "/usr/lib/collectd/"
+
+exec-munin.px
-------------
- A sample config file. Used by the Debian package.
+ Script to be used with the exec-plugin (see collectd-exec(5) for details)
+which executes munin plugins, parses the output and translates it to a format
+the exec-plugin understands. The features are limited - changing the munin
+plugins to use the output format understood by the exec-plugin is recommended.
+See the embedded POD documentation for more details:
+ $ perldoc contrib/exec-munin.px
-collection.cgi
+exec-smartctl
+-------------
+ Sample script for the exec plugin. Please refer to the documentation in the
+file - you will have to adapt it to your needs anyway.
+
+extractDS.px
+------------
+ Creates a new RRD-file with only one data-source (DS) of the source-RRD-
+file. That is very handy when you realise that you have bundled up DSes in one
+RRD-file that should have been in multiple RRD-files instead. Is is used by
+`migrate-3-4.px' to split up the cpu-, nfs-, swap-files and possibly others.
+
+fedora/
+-------
+ Init-script and Spec-file that can be used when creating RPM-packages for
+Fedora.
+
+migrate-3-4.px
--------------
- Sample CGI script that creates graphs on the fly. The Perl module `RRDs' is
-needed (Debian package `librrds-perl').
+ Migration-script to ease the switch from version 3 to version 4. Many
+RRD-files are expected in a different place, some have been changed (DSes have
+been renamed) and others have bee split up into multiple files. This script
+prints a bash-script to STDOUT which should do most of the work for you. You
+may still need to do some things by hand, read `README.migration' for more
+details.
-init.d-rh7
-----------
- Sample init script. Used by the RPM specfile.
+snmp-data.conf
+--------------
+ Sample configuration for the SNMP plugin. This config includes a few standard
+<Data ..> definitions that you can include in your own config using the
+`Include' statement (available since version 4.2.0). The config includes some
+data that is defined in the IF-MIB, e. g. octet or packet counters, UPS-MIB and
+whatever people have send in. If you have some more definitions please send
+them in, so others can profit from it.
