Network Calls Apdex

Luciq calculates an Apdex score for every network request (URL pattern) in your app. Apdex score ranges between 0 and 1. The higher the value, the closer you are to satisfying a user experience:

• Apdex score ≥ 0.94 equates to Excellent performance.

• Apdex score ≥ 0.85 and < 0.94 equates to Good performance.

• Apdex score ≥ 0.7 and < 0.85 equates to Fair performance.

• Apdex score ≥ 0.5 and < 0.7 equates to Poor performance.

• Apdex score < 0.5 is considered Unacceptable.

How Is the Network Calls Apdex Calculated?

When a network call occurrence is collected, it is flagged based on a pre-defined target (T). A network call occurrence is considered:

• Satisfying: if its duration ≤ T

• Tolerable: if its duration > T and ≤ 4T

• Frustrating: if its duration > 4T or if it fails due to a server-side or client-side error.

Then, based on the bucketing explained above, the Apdex is calculated:

• Total occurrences = Satisfying occurrences + Tolerable occurrences + Frustrating occurrences

• Apdex score = (Satisfying occurrences + 0.5 * Tolerable occurrences) / Total occurrences

How Can You Control a Specific Network Call's Target?

By default, it is set to 0.5 seconds; however, you can easily change this number from your dashboard by clicking on the action highlighted in the screenshots below.

📘 Please note that updating your response time target does not affect the already stored occurrences; only future occurrences will be flagged using the new target.

Network Latency Breakdown

You can see the P50s, P95s, and the frequency of each stage/operation that occurred inside a network group. These are the stages/operations that were made to send the network request and receive its response from the server.

The feature works out of the box without any instrumentation, and the stages are shown inside the Spans table inside the Network metric.

The spans table contains the following stages:

• DNS Lookup

• Connection Handshake

• TLS Connection

• Uploading Request

• Downloading Response

• Server Processing

You can also see the breakdown and visualize the stages' timeline on an occurrence level inside the occurrences page.

📘 Minimum SDK Version

The minimum required SDK version for this feature is v12.1.0.

URL Patterns

URL patterns are used to group the relevant network call occurrences and aggregate their numbers. Let's take the following examples:

• sample.com/list/3/item/1

• sample.com/list/3/item/2

• sample.com/profile/

It looks like 1 and 2 are the same request, but asking for different resources. While 3 is an entirely different one. Those three examples result in the following 2 URL patterns:

• sample.com/list/*/item/*

• sample.com/profile/

What Are the URL Pattern Components?

• Plain text: works with exact string matching

• *: matches with any URL part. * matches with only one part at a time. For example if you are mapping sample.com/part/variable1/variable2, your pattern should be sample.com/part/*/* and not sample.com/part/*

Does Luciq Detect Patterns Automatically?

Luciq automatically detects numbers and hexadecimal tokens in your URLs and replaces them with *.

Can You Create Custom Patterns?

If you are using more complex URLs where variable parts may contain plain text and not only numbers and hexadecimal, we recommend defining your custom patterns. Just click on the "Create URL pattern" button in your network list.

Click on the highlighted action to create new URL patterns. URL patterns are used to group relevant network calls.

Here are a few examples:

URL pattern example	Matches with	Doesn't match with
sample.com/part1/part2	sample.com/part1/part2	sample.com/part1
sample.com/part1/*	sample.com/part1/part2	sample.com/part1/part2/part3
sample.com/part1/*/part3	sample.com/part1/part2/part3	sample.com/part1/part3/part4 sample.com/part1/part2/part3/part4
sample.com/part1/*/*/part4	sample.com/part1/part2/part3/part4	sample.com/part1/part2/part4 sample.com/part1/part2/part3/part4/part5
sample.com/part1/*/*/*	sample.com/part1/part2/part3/part4	sample.com/part1/part2/part3/part4/part5 sample.com/part1/part2/part3
sample.com/part1/**/part5	sample.com/part1/part2/part3/part4/part5	sample.com/part1/part2/part3/part4/part8

Some notes to consider while creating your URL patterns:

• Custom URL patterns that you define have higher precedence than the auto-generated ones. If the same call matches with a custom and an auto pattern, it gets grouped with the custom.

• At any point, you can delete a pattern to prevent grouping new calls with it.

• URL patterns shouldn't overlap. Each incoming network call gets grouped with only one pattern. In case of conflict, it gets merged with the newest pattern.

Creating or deleting patterns doesn’t affect your old data that has already been grouped. It only affects the upcoming network requests.
