1 The files in this directory may be used to perform common tasks that aren't
2 exactly `collectd's job. They may or may not require in-depth knowledge of RRD
3 files and/or `collectd's inner workings. Use at your own risk.
7 Perl modules to be used in conjunction with collectd. See the perldoc
8 documentation of the .pm-files to find out what they're good for.
12 Before version 3.9.0 collectd used to create a different set of RRAs. The
13 most detailed of these old RRAs had a one minute resolution. This script can
14 be used to add three more RRAs: minimum, maximum and average with a ten second
15 resolution and 2200 rows (~6 hours). This will make hourly statistics much more
16 interesting. Please note that no sanity- checking whatsoever is performed. You
17 can seriously fuck up your RRD files if you don't know what you're doing.
21 This script by Vincent Stehlé will search for RRD files in
22 `/var/lib/collectd/' and generate an HTML file and a directory containing
23 several PNG files which are graphs of the RRD files found.
27 Sample CGI script that creates graphs on the fly. The Perl modules `RRDs'
28 (Debian package `librrds-perl'), `URI:Escape' (package liburi-perl),
29 `HTML::Entities' (package libhtml-parser-perl) and a CGI capable web server
30 (e.g. apache2 or boa) are needed. Simply install the script to a place where
31 the webserver will treat it as a CGI script (/usr/lib/cgi-bin/ by default) and
32 visit that page in a browser (http://localhost/cgi-bin/collection.cgi by
33 default). Please refer to your webserver's documentation for more details.
35 Starting with version 4, collection.cgi requires a small config file, which
36 should look something like this:
38 datadir: "/var/lib/collectd/rrd/"
39 libdir: "/usr/lib/collectd/"
43 Script to be used with the exec-plugin (see collectd-exec(5) for details)
44 which executes munin plugins, parses the output and translates it to a format
45 the exec-plugin understands. The features are limited - changing the munin
46 plugins to use the output format understood by the exec-plugin is recommended.
47 See the embedded POD documentation for more details:
48 $ perldoc contrib/exec-munin.px
52 Creates a new RRD-file with only one data-source (DS) of the source-RRD-
53 file. That is very handy when you realise that you have bundled up DSes in one
54 RRD-file that should have been in multiple RRD-files instead. Is is used by
55 `migrate-3-4.px' to split up the cpu-, nfs-, swap-files and possibly others.
59 Init-script and Spec-file that can be used when creating RPM-packages for
64 Migration-script to ease the switch from version 3 to version 4. Many
65 RRD-files are expected in a different place, some have been changed (DSes have
66 been renamed) and others have bee split up into multiple files. This script
67 prints a bash-script to STDOUT which should do most of the work for you. You
68 may still need to do some things by hand, read `README.migration' for more
