The files in this directory may be used to perform common tasks that aren't exactly `collectd's job. They may or may not require in-depth knowledge of RRD files and/or `collectd's inner workings. Use at your own risk. PerlLib/ -------- Perl modules to be used in conjunction with collectd. See the perldoc documentation of the .pm-files to find out what they're good for. add_rra.sh ---------- Before version 3.9.0 collectd used to create a different set of RRAs. The most detailed of these old RRAs had a one minute resolution. This script can be used to add three more RRAs: minimum, maximum and average with a ten second resolution and 2200 rows (~6 hours). This will make hourly statistics much more 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. collectd2html.pl ---------------- This script by Vincent Stehlé will search for RRD files in `/var/lib/collectd/' and generate an HTML file and a directory containing several PNG files which are graphs of the RRD files found. 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/" 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 -------------- 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.
