The Transparent RAID UI dashboard is designed to show various charts.
Each type of chart needs to be configured and enabled before it is shown.
One type of charts displayed in the dashboard are statistics on the data files comprising the array.
1. Until charts are enabled, the dashboard will show nothing.
2. Files are categorized and grouped by file extensions, and reporting is done on each defined category.
Categories are defined in the UI “Preferences” settings under the “File Statistics” tab.
Some categories have been defined by default and you can add new ones and remove or edit old ones.
3. The next step is to enable “File Statistics” for a particular RAID configuration.
This is done by accessing the RAID configuration options and setting the required property value as shown below.
4. Finally, you will need to schedule the “File Statistics” job for the chosen array.
Each time the job runs, it first checks whether “File Statistics” is enabled for the array and then proceeds if true.
As scheduled jobs cannot be edited (they can only be cancelled and re-scheduled), the way to pause/skip “File Statistics” is to set the RAID property option to false.
Scheduling of the job is done through the scheduler. You first have to select the RAID configuration and then select “File Statistics” as job.
5. Depending on the number of files contained in your array, the job might take anywhere from a few seconds to several minutes or possibly longer to run. Regardless of the duration, reloading the UI should show the charts.
The charts will vary based on the data content of the array and your category settings.
Charts are not rendered when their portlets are minimized. Maximizing the portlets afterward will draw the charts.
You can use this behavior to minimize what gets rendered when you have a lot of portlets in the dashboard for a faster page load.
