Facette 0.5.0rc1 released

We know that it’s been quite some time since the latest release. But wait no more, the first release candidate of the 0.5.0 is here!

What’s new

TL;DR

• Warm startup
• Syslog logging
• Keyboard shortcuts
• Duration Y axis unit
• Y axis extremes support
• Aliases in the URLs
• Rearranged configuration
• UI improvements

Warm startup

Using Facette with back-ends having thousands of sources and metrics can really slow down its startup process.

Starting with this release, Facette will persist its internal catalog state across restarts to ensure the service is available as quickly as possible when launched.

Syslog logging

Along with console and file logging previously available in Facette. It’s now possible to send logging information to a local or a remote Syslog instance.

See configuration for details.

Keyboard shortcuts

Keyboard shortcuts support has been added to the front-end. By pressing “?” you’ll be presented a list of available shortcuts to perform basic actions or to jump to different sections of the front-end UI.

Duration Y axis unit

Facette now supports a “duration” Y axis unit type. Choosing duration and a base unit will automatically format values as durations.

Y axis extremes support

Extreme bounds support has been added to the front-end rendering of graphs. By setting minimum and/or maximum values, you can limit the range of the rendered area.

Aliases in the URLs

As of today, graphs and collections aliases are supported in the URL. This will allow the usage of user friendly URLs instead of Facette’s internal identifiers.

Rearranged configuration

The configuration has been rearranged into functional sections, making the old configuration incompatible.

See example configuration for details.

UI improvements

This release comes with a lot of fixes and minor improvements to the front-end side of Facette.

Last but not least, some under-the-hood changes in this release:

• the switch to HTML Canvas for graphs rendering, greatly improving the UI responsiveness when browsing quite large collections;
• provider startup errors are now reported in the associated administration panel section, to avoid looking at the logs in case of a simple misconfiguration;
• missing data points interpolation has been drop, automatically detecting gaps to prevent rendering bugs.
