Filter use cases

[skliche]

As a user I want to be able to filter events in the use cases list based on

• timestamp (from, to)
• elapsed time (show values bigger than x)
• types (dropdown, multiple types at the same time)
• details (free text search, wildcards, regex)

The different filters can be selected and specified in a new toolbar at the top of the business transactions table, that will basically look like the toolbar in the transaction drilldown panel. You can see how it could look like in the attached wireframe:

As you can see, the user should have multiple options to filter, that can also be combined (e.g. all events of types "EJB" and "Servlet Filter" that took more than 50ms of elapsed time can be shown). The filters should all be cleared by clicking the red cross button on the right.

As we have a second toolbar now, we will likely move the toolbars into a separate class in the GUI package to reduce complexity in the "RequestMetricsGui" class.

For filtering the time stamp, we have added two date-time pickers to the toolbar. All filters are applied directly upon user input and can be combined. The red cross button on the right is (for now) just a button that says "clear".

There persist some issues that still need to be resolved:

• the combo box we user for filtering types closes after every selection of an element
• problems with JCalendar (that we use for picking a date & time to filter for):
  • the combo boxes of the pickers take too much space away in our toolbar - maybe the displayed format is changeable
  • default start and end value of the pickers should be set by our data (i.e. start picker should default be set to earliest time stamp of the log)
  • the time picker should maybe allow changing milliseconds, to filter more exactly
  • time picker does not work properly for "second" value, only for minutes and hours
• when a file is loaded and the user opens new file dialog but cancels it, we have different problems with the GUI, e.g. an empty table is shown
• labels and their according input fields could visually be grouped by a border (as we see in the wireframe)

The following issues are still open:

• the combo box we user for filtering types closes after every selection of an element
• the time picker should maybe allow changing milliseconds, to filter more exactly

There are also some issues with lower resolution clients that need to be fixed. I will reproduce the issues and crate a ticket.
