App Experience Analytics
uses the following terms:
Active User
An
Active User
is one who has launched and used the application during the selected time period.
Affected Users
The number of users who are affected by the crash. This metric (Total Affected Users) is displayed in the Analytics and App Crashes pages and Error/List of Crash Types section.
App Startup Time
App User Retention
The retention visualization represents the percentage of users of a time cohort who were active after their start date. The percentage of users of a time cohort who logged an event on the nth day after their start date. For example, Day 8 means the eight days after the new user has started. The percentage represents retention. This is a powerful way to see if an application is sticky or if users download the application once and never return. With the retention chart, you can see if the users come back to the app.
Average Load Time
Average time that is taken to load the screen.
Average load time = Sum of the load times for the screen / Number of views.
Average Duration
Average Request Latency (Average per Request)
Impact of the average latency on the application as a result of network calls from the applications.
Average Spin Time
Sum of the spin times for the screen / Number of views.
CPU Usage
Average CPU consumed by the application per session.
Crash Count
Number of crashes.
Crashed Transactions
Transactions that were aborted due to an app crash.
Data Sent
Average data that is sent per request per session.
Data Sent:
(Sum of Data Sent for all network events) / (Successful sessions)
Data Received
Average data that is received per request per session.
Data Received:
(Sum of Data Received from all network events) / (Successful Sessions)
Disk Space
Disk space of the device.
Domain Lookup
Time taken to look up the domain in milliseconds.
Drop Percentage
Percentage of users who exist the app from a particular screen. For example, if a user accessed a particular screen 10 times and has ended their session 5 times on this screen, the drop percentage is 50 percent.
# of Screens (Screen Rank)
Represents the popularity of the screen. For example, #6 of 32 screens indicates that this screen ranks 6th of the 32 screens. The total of 32 screens represents the total number of unique screens that have been accessed in the application.
Errored Transactions
App transactions that have been recorded as errored though the CA App Experience Analytics SDK API.
First Occurrence
First occurrence of the crash.
Flagged Sessions
Sessions for which the application metrics have crossed the defined threshold values.
Global Administrator
A Global Administrator is the second level in the administration hierarchy, and can create tenants, administrators, and users. A Global Administrator can be granted permissions to manage all tenants or a specific group of tenants. A Global Administrator can also create a custom role that has only specific privileges.
In a SaaS deployment, a Global Administrator belongs to the organization that is hosting the solution.
High Load Time Count
Number of times the load time for the screen exceeded 500 millisecs.
High Spin Time Count
Number of times the spin time for the screen exceeded 500 millisecs.
Incomplete Transactions
Transactions where the app has initiated the start of a transaction but has not executed the corresponding end transaction. A crashed transaction could sometimes be counted as Incomplete if the end transaction was not executed because the app crashed ahead of it.
Included in Services
Captures the services that the transaction in question was a part of. If the service name was not specified, by default, CA App Experience Analytics considers name of the app as the service and associates the transaction with the name of the app.
Highest Usage App
Application that has the highest number of user sessions. The scoring is relative.
HTTP Requests (Average per Session)
Number of HTTP requests made by the application per session during the selected time period.
HTTP Errors (Average per Session)
Average number of erroneous HTTP requests made by the application per session during the selected time period.
Last Occurrence
Last occurrence of the crash.
Least Performance App
Application for which the startup time and the HTTP response time have exceeded the threshold.
  • Startup Time (60 percent Weightage): 500 millisecs
  • HTTP Response Time (40 percent Weightage): 200 millisecs
Least Performant App Score
The Least Performant App Score is calculated as follows:
A = (Total application sessions with startup time > 500 ms / Total sessions with startup time > 0) * Weight
B = (Total application sessions with HTTP latency > 200 ms / Total sessions with HTTP latency > 0) * Weight
App score of an application = A + B
Master Administrator
A Master Administrator is a predefined administrator account. This account is the first level in the administration hierarchy. The username of a master administrator is masteradmin. A Master Administrator creates and updates Global Administrators.
In a SaaS deployment, a MA belongs to the organization that is hosting the solution.
Memory Use
Average memory that is consumed by the application per session.
Mobile Transactions
Mobile transactions that happen on your mobile device. These transactions are categorized into:
  • Automated: Transaction that the SDK creates and they are displayed in the App Transactions page
  • Instrumented: Transactions that are created by a user and they are displayed in the App Transactions page.
Most Problematic App
Application that has the maximum number of crashes and HTTP errors.
  • Crashes: 70%
  • HTTP Errors: 30%
New User
A
New User
is one who has launched and has used the application for the first time during the selected time period. 
Number of Sessions
Number of sessions that included the screen.
Number of Views
Number of views.
% of Interactions
Interactions represent the user touching, tapping, or manipulating the screen in some way. The % of interactions is the number of times a user interacted with this screen and is calculated as follows: (Number of interactions with this screen / Total number of screen views) * 100
Orientation
Orientation of the screen. For example, portrait or landscape.
Page Load Time
Time taken to load the page in milliseconds.
Power User
A Power User has access to the analytics data. They can only view data that are related to the application and application versions but they cannot create or delete an application. However, a PU can view or update alerts and application settings. A Global Administrator, Tenant Administrator, or an User Administrator can create a Power User.
Problems Detected
A problem is detected when the Warning Threshold for an alert has exceeded the configured value.
Sampling
Collect sample data only from the specified percentage of user sessions. For example, Sampling % data is set as 90%. For every 100 events, data for 90 events is collected. For the 10 events that are not collected, information about crashes and not errors is collected.
Slow Transactions
Dynamic computation of slow transaction marks a transaction as slow if the transaction takes at least 1000 millisecs to complete or takes longer than the moving average of the completion time for the selected time period.
Spin Time Percentage
Startup Time
Time the application takes to launch its first activity. App Experience Analytics detects the load time of the applications main class when the application finishes launching and treats the difference of the two epochs as the startup time.
High Spin Time Count
Number of times the spin time for the screen exceeded 500 millisecs.
High Load Time Count
Number of times the load time for the screen exceeded 500 millisecs.
Symbolication
The process of converting the crash details to a human-readable format is referred to as symbolication.
App Experience Analytics
supports converting a crash stack trace to a human-readable format.
Tenant Administrator
A Tenant Administrator is the third level in the administration hierarchy. A TA performs a subset of tasks that a GA performs. A Tenant Administrator can perform administrative tasks only in the scope of the tenant account to which they belong.
In a SaaS deployment, a Tenant Administrator belongs to the tenant organization.
Threshold Exceeded
A threshold is exceeded when the Critical threshold that is set for an alert is exceeded.
Transaction
A transaction is  a unit of business action that is aimed to deliver a specific business outcome.
Total Page Hits
Total number of unique URLs that have been hit. 
User Administrator
A User Administrator is the lowest level in the administration hierarchy. They can perform all tasks that are related to the user management for the tenants that are assigned to them either by a Global Administrator or a Tenant Administrator. The User Administrator creates and manages users, as required.
In a SaaS deployment, a User Administrator belongs to the tenant organization.
User
Each employee of the enterprise is referred to as a user. A user record can exist either in the enterprise LDAP repository or in the
App Experience Analytics
database. Using the Administration Console, a Global Administrator and Tenant Administrator can create and manage users in the
App Experience Analytics
database. A Global Administrator and Tenant Administrator can also manage the
App Experience Analytics
-specific data of users whose records are in the LDAP repository. This data is stored in the
App Experience Analytics
database.
