How to Work with User-Defined Attributes (UDA) in Link Master Analysis
In this article, we'll show you how you can create user-defined attributes (UDAs) and how they can help you study your device or network.
Prerequisites
Before you begin this tutorial, please load your log files into your Link Master Analysis (LMA) workspace. As you work through this tutorial, you can use any file you'd like.
Create a User-Defined Attribute
User-defined attributes are mathematical manipulations of attributes that you've loaded. For example, let's say that you have the RSRP of the primary sector and the RSRP of the primary sector's nearest neighbor. Suppose you're interested in the difference between these two values. Let's create a UDA to help you identify this difference.
In your workspace, select the file you'd like to use. Then, in the navigation panel below, open up the UDA tab.
Right-click anywhere in this tab and select New UDA.
This launches the UDA wizard.
Begin by providing a name for your UDA.
Using the left-hand panel, find the attribute you want included in your UDA.
Drag and drop the attribute onto the panel immediately to the right of your list of attributes.
Repeat this process for all attributes you want included. Note that each attribute you included automatically gets an alias. This is used when you define the operations you want performed.
Then, define the math operations you want to perform on your attributes.
Set the display options for the calculated value. For example, you might want to change the number of decimal places LMA shows.
Click Apply to save your new UDA. You'll see your UDA displayed in your list of UDAs.
You can now use your UDA anywhere you'd normally use a default attribute.
Set the Legend for a UDA
You can set the legend for your UDA. To do so, right-click on your UDA and select Set Legend.
This brings up the Legend Configuration wizard.
Right-click and select Add Section. Repeat as necessary until you have the number of desired sections.
For each section, you can set its:
- Visibility
- Symbol
- Size
- Color
- Operator
- Value
- Alias
Your final legend might look something like this. Click OK to save your legend.
This is how your legend looks in use.
Other Types of UDAs
Event Message Duration UDAs: creates UDAs so you can look at the timing between two or more messages
Result Duration UDAs: creates UDAs so that you can look at the durations between multiple attributes
