There are many customizations that can be done in Bugzilla.

General Preference

Email Preference: Here, the user can set any notifications emails they want to receive.

Bugzilla has a lot of filter options, using which we can generate customized reports.

The fields that are present in generating a report are:

  • Vertical Axis – Any field that is represented along your Y-axis.
  • Horizontal Axis – Any field that is represented along your X-axis.
  • Multiple Tables – Defines how the report generated will be grouped.

Let us generate a report and see how Bugzilla interprets the options.

Generate a report

Now, give the values in Vertical Axis -Assignee, Horizontal Axis-Bug ID field, and multiple tables-Status.

Enter some string for the search and click on Generate Report.

The report generated looks as shown below.

Report generated continue

So the report is grouped based on the field specified in the Multiple Tables field and the respective X and Y-axis have been populated.

Now, at the page’s bottom, there is an option for the user to view the same report in Bar chart, Line Chart, or a CSV format report.

CSV format report

Also, the user can save the report using the Remember Report option at the bottom of the page.

Enter a report name and click on Remember Report.
