# Crasheye platform terminology
collapse: A flash back occurs during the user's use of app, counted as a crash.
Script exception: Exception, Error, or Script (such as C # , Lua, JS, etc.) errors that are actively reported are collectively referred to as Script exceptions.
Crash count: an exception occurs and is reported as an exception.
Number of uses: also known as “Number of startup”. Each time the application is started and reported, the following scenarios count as one start:
After the application exits completely, restarts, counts as a start;
Application is switched to the background, 30 seconds after the switch to the front desk, counted as a start, if not more than 30 seconds to the front desk, not a start.
Crash rate: crash rate = the percentage of crash times divided by startup times in the selected time period.
Number of affected users: an exception occurred on one device, counted as an affected user. In the specified time range, if a device occurs multiple exceptions, only one affected user is counted.
Number of users: also known as “Active users”. Take the device as a statistical object, the application starts on a set, and reports, counted as a number of users. Within a specified time range, if a device is reported more than once, it is only counted as one user.
Affected user rate: affected user rate = number of affected users divided by the percentage of number of users
Number: the Crasheye platform identifies each outage with a rule-based ordinal that is unique in a single Appkey.
Statistical Time: Based on the East 8 time zone, if the project is published globally, the possible impact of the time zone on the data needs to be considered.
Crash Time: the time on the user’s machine at the time of the crash.
Time to report: the time the server received the crash message. Because with”crash time”get host is different, may appear to report the possibility that the time is earlier than crash time.
Client ID: uniquely identifies a device that can be used to retrieve all of the device’s crash records at a single device. Application reloading may generate different client ids.
Foreground/background: when a crash occurs, is the application running in the foreground or in the background.
Usage: the time elapsed between when the last full exit started and when the crash occurred.
UUID (symbol file) : is the unique identifier for the symbol file, which is regenerated after each compilation and packaging of the project. Crasheye uses this information to associate an outage stack with a symbol file.
Crash rate of the day: the percentage of today’s crash times divided by startup times, the data is refreshed every few minutes
