Collectd Graph Panel v0.4

After 2,5 years and about 100 commits I’ve tagged version 0.4 of Collectd Graph Panel.

This version includes a new interface with a sidebar for plugin selection.

Javascript library jsrrdgraph has been integrated. Graphs will be rendered in the browser using javascript and HTML5 canvas by setting the “graph_type” configuration option to “canvas”. This saves a lot of CPU power on the server. Jsrrdgraph has some nice features. When rendered, you can move through time by dragging the graph from left to right and zoom in and out by scrolling on the graph.


The Collectd compatibility setting has been changed to Collectd 5. If you’re still using Collectd 4, please set the “version” configuration setting to “4”, otherwise the graphs of a couple plugins won’t be showed right (like the interface, df, users plugins).

In this version of CGP, total values are added to the legend of I/O graphs and generated colors will be created using a rainbow palette instead of 9 predefined colors. Please read the changelog or git log for more information about the changes.

New plugins:

Special thanks for this version go to Manuel Luis, who developed jsrrdgraph, xian310 for the new interface, Manuel CISSÉ, Rohit Bhute, Matthias Viehweger, Erik Grinaker, Peter Chiochetti, Karol Nowacki, Aurélien Rougemont, Benjamin Dupuis, yur, Philipp Hellmich, Jonathan Huot, Neptune Ning and Nikoli for their contributions.

I’ve been using GitHub for a while now. You can download or checkout this version of CGP from the GitHub URL’s below. When you have improvements or fixes for CGP, don’t hesitate to send in a Pull Request on GitHub!

v0.4.1 update

I just removed the dependency on mod_rewrite when using jsrrdgraph to draw the graphs. This may solve javascript error: Invalid RRD: “Wrong magic id.” undefined.
