Data Explorer and Data Cubes

Data Explorer and its individual cubes allow you to view, filter, and manipulate data in many different ways .

Data Exploration

Data exploration is the act of examining the minute details of an Online Analytical Processing (OLAP) cube.

Consider your data to be a three-dimensional cube that you would like to explore, both inside out and outside in, so that you can glean more insights from your data. Of course, most real world data sets will have more than three dimensions, but the concepts from a 3D cube can be directly extended to a multidimensional hypercube.

With an OLAP cube, there are five operations that you can perform:
  1. Slice: Think of slicing a piece of cheese; you make a single cut to the cheese to expose the insides. A typical slice operation is the time slice. Instead of reviewing all the data of the last 30 days, you slice the data to expose only Day 1.
  2. Dice: Consider dicing a block of cheese; you make multiple cuts and separate the block into a number of smaller pieces. A typical dice operation involves taking a slice of data, such as the Day 1 data, and cutting it further to filter by the venue name and AP group. A smaller piece of the original OLAP cube results from the slice and dice operations.
  3. Drill Up and Drill Down: In order to delve into the details, you can drill down to a specific AP in an AP group, and drill down further to a specific client host name. Conversely, you could search for a client MAC address and drill up to find the AP and venue to which it belongs.
  4. Roll Up: The roll up operation typically involves numbers known as measures. After the slice, dice, and drill down of your data, you can roll up the numbers to gain a better understanding of the whole, for example, the total transmit traffic for the selected APs.
  5. Pivot: The pivot operation allows you to view the data from a different perspective. Think of pivoting as changing the hierarchy between the dimensions.
As you use the custom reporting, you can refer to these five operations.

Data Explorer allows you to explore the data under various categories, using your own permutations and combinations, unlike the other canned reports available.

NOTE
The Schedule tab is for use only with dashboards you create, not with data cubes themselves.
For information on how to use data cube filters, which are common to all the data cubes, refer to Data Cube Filters. You can also create and save dashboards, which allows you to customize reports by using data from any or all of the data cubes. Refer to Creating a Data Explorer Dashboard and Actions You Can Perform on an Existing Dashboard for more information.

Rogue APs

The Rogue APs cube allows you to view information about APs that have been flagged as "Rogue" because they cannot be identified by existing APs in your system.
