Avg Issue Rate/Performance Weather
You can check the Avg Issue Rate in the past 30 minutes and Performance Weather indexes.
Avg Issue Rate: Calculates the average problem occurrence rate in which the data rate exceeds the threshold value of each performance index (UI Rendering Time, Response Time, CPU, Memory, and crash) for the past 30 minutes.
Performance Weather: Displays five-level weather icons depending on the Avg Issue Rate for the past 30 minutes.
| Index | period | value | Merging method |
|---|---|---|---|
Avg Issue Rate | Recent 30 minutes | Issue Rate | Issue Rate of each performance indexes (Data above threshold / All data) * 100 |
Performance Weather | Recent 30 minutes | Avg Issue Rate | ~20%, Step 5 |
The Avg Issue Rate and Performance Weather are useful in identifying the app-based performance for the past 30 minutes. The performance is quickly evaluated through the top evaluation index for each app.
4. Performance Issue Rate
Displays the problem occurrence rate of five performance indexes for the past 30 minutes on a graph, including crash, memory usage, CPU, response time, and UI rendering time. It displays the ratio of the data that exceeds the threshold of each performance index. You can compare the current app version with the previous app version. Comprehensive status is updated every minute.
Issue Rate: Calculates the problem occurrence rate by performance index for the past 30 minutes.
| index | period | value | Merge method |
|---|---|---|---|
Crash | Recent 30 minutes | Issue Rate | mber of occurred crashes /app launches |
Memory | Recent 30 minutes | Issue Rate | (Data above threshold / All data) * 100 |

You can set the threshold by performance index at “Management > Project Preset”.
5. Time series performance information
Displays the number of occurred crashes, the average of the bottom 5% and the total average of the performance indexes (UI rendering time, response time, CPU, and memory usage) for the past 30 minutes on a time-series graph. You can check the point of performance degradation and trends of performance changes. Time series performance information is updated every minute.
Current Users & Runs
You can check and compare the user count and app launches for the past 30 minutes in one-minute interval. ‘Current users & Runs’ is updated every minute.
Current user: Counts the current user that occurred for the past 30 minutes in one-minute intervals. The count refers to the number of users alone, excluding duplicates.
Run count: Counts the app run count that occurred for the past 30 minutes in one-minute intervals.
Crash
You can check the number of occurred crashes for the past 30 minutes in a one-minute interval. Crash information is updated every minute.
Crash: Counts the number of crashes that occurred for the past 30 minutes in one-minute intervals.
Rendering Time
You can check the UI rendering time for the past 30 minutes in a one-minute interval. Displays the total average and the average of bottom 5%, and the UI rendering time is updated every minute. (For React Native, you can check the screen/component loading time.)
Bottom 5%: Calculates the UI rendering time of bottom 5% on average for the past 30 minutes.
Average: Calculates the total UI rendering time on average for the past 30 minutes.
| index | period | value | Merge method | Unit |
|---|---|---|---|---|
Bottom 5% | Recent 30 minutes | UI rendering time | Average of the bottom 5% | ms |
Average | Recent 30 minutes | UI rendering time | Total average | ms |
The horizontal line displayed in the graph indicates the performance threshold, which enables you to easily check the time and value when the performance issue above the threshold has occurred.
The Y-axis indicates the UI rendering time. Bottom 5% is calculated by sorting all data collected by IMQA in the order of the longest UI rendering time, which enables you to compare the average rendering time with that of some users. If the difference between bottom 5% and average is small, we can see that most users experience similar app usability.
Response Time
You can check the response time for the past 30 minutes in a one-minute interval. Displays the total average and the average of bottom 5%, and the response time is updated every minute.
Bottom 5%: Calculates the response time of bottom 5% on average for the past 30 minutes.
Average: Calculates the total response time on average for the past 30 minutes.
| index | period | value | Merge method | Unit |
|---|---|---|---|---|
Bottom 5% | Recent 30 minutes | Response time | Average of the bottom 5% | ms |
Average | Recent 30 minutes | Response time | Total average | ms |
The horizontal line displayed in the graph indicates the performance threshold, which enables you to easily check the time and value when the performance issue above the threshold has occurred.
Bottom 5% is calculated by sorting all data collected by IMQA in the order of the longest response time, which enables you to compare the time to respond to user requests on average with some performance degradation situations. If the response takes long, we can check whether there were any network or server problems at a specific time, and analyze in which environment the user experienced performance degradation in connection with “Comprehensive Status”.
CPU
You can check the CPU usage for the past 30 minutes in one-minute intervals. Displays the total average and the average of bottom 5%, and the CPU is updated every minute.
Bottom 5%: Calculates the CPU usage of bottom 5% on average for the past 30 minutes.
Average: Calculates the total CPU usage on average for the past 30 minutes.
| index | period | value | Merge method | Unit |
|---|---|---|---|---|
Bottom 5% | Recent 30 minutes | CPU usage | Average of the bottom 5% | % |
Average | Recent 30 minutes | CPU usage | Total average | % |
The horizontal line displayed in the graph indicates the performance threshold, which enables you to easily check the time and value when the performance issue above the threshold has occurred.
Bottom 5% is calculated by sorting all data collected by IMQA in the order of the highest CPU usage, which enables you to compare the average CPU usage while the app is running with some performance degradation situations. On average, the threshold of app CPU usage is less than 50%. If it exceeds 50%, we can see that the app performs many tasks that use the CPU.
Memory
You can check the memory usage for the past 30 minutes in a one-minute interval. Displays the total average and the average of bottom 5%, and the memory usage is updated every minute.
Bottom 5%: Calculates the memory usage of bottom 5% on average for the past 30 minutes.
Average: Calculates the total memory usage on average for the past 30 minutes.
| Index | period | value | Merge method | Unit |
|---|---|---|---|---|
Bottom 5% | Recent 30 minutes | Memory usage | Average of the bottom 5% | MB |
Average | Recent 30 minutes | Memory usage | Total average | MB |
The horizontal line displayed in the graph indicates the performance threshold, which enables you to easily check the time and value when the performance issue above the threshold has occurred.
Bottom 5% is calculated by sorting all data collected by IMQA in the order of the highest memory usage, which enables you to compare the average memory usage while the app is running with some performance degradation situations. On average, the threshold of app memory usage is less than 100MB. If it exceeds 100MB, we can see that the app performs many tasks that use the memory.
6. Screen performance
You can check the performance status by the screen visited by the user for the past 30 minutes. You can monitor the user visit rate by screen, problem occurrence rate of each performance item, and the bottom 5% and the average. Screen performance is updated every minute.
The Screen performance consists of the following:
❶ Performance index You can change the performance index to “UI rendering time”, “Response Time”, “CPU”, or “memory usage”. If you change the index, the bottom 5% and the average displayed on the screen cards below are updated.
❷ Screen Card Sorting Defaults to “By Visit Rate”; Cards can be sorted “By Visit Rate,” “By Issue Rate,” “By Bottom 5%,” or “By Average” in descending order (highest to lowest).
❸ Screen type filter By default, the filter is set to “Total”. Filters are displayed that can be selected according to the app type selected at the time of project creation. For the WebView/hybrid app, screen cards can be filtered by “Native” and “WebView”.
❹ Total screen analysis table You can quickly check the performance status of each screen visited by users for the past 30 minutes in summary.
➎ Screen cards You can check the visit rate by screen visited by users for the past 30 minutes, the problem occurrence rate, the bottom 5%, and the average values.
For React Native, CPU and memory performance metrics are displayed centered on native data. The component screen card display function in the response time performance indicator will be updated in the future.
Total screen analysis table
You can quickly check the problem occurrence rate of each screen visited by users for the past 30 minutes. A pop-up window is displayed if the [Total Screen Analysis Table] on the right is clicked.
The screen is sorted in the order of the highest visit rate, and displays the ratio of the data that exceeds the threshold set in “Manage > Project Preset” as a problem occurrence rate. The danger level is indicated in colors depending on the problem occurrence rate.
Based on this, you can check the performance degradation on the screen with a high visit rate at a glance. In addition, you can analyze performance degradation factors, such as whether the app users experienced problems in rendering on average, and whether the response to requests was slow.
Screen cards
You can check the visit rate by screen visited by users for the past 30 minutes, the problem occurrence rate, the bottom 5%, and the average values. The screen is sorted in the order of the highest visit rate. When you click on the screen card, the “Screen Performance Analysis” page will be displayed.
❶ Screen information Displays information such as screen type and path. Native screens display the ‘Native’ tag, and web view screens display information about the native screen that called the web view.
❷ Screen name Displays the name of the screen. If the screen name is too long, hover the mouse over the name to display the full name as a tooltip. You can change the screen name in such a way that it can be easily understood in IMQA by selecting “Manage > Screen Name”.
❸ Problem occurrence rate / Rate of visit / Performance information Displays the problem occurrence rate of the user who visited a specific screen for the past 30 minutes. The rate is displayed in color according to the rate. Displays the bottom 5% and the average value based on the rate of visits to a specific screen for the past 30 minutes and the performance standards.
Based on this, you can check the performance degradation on the screen with a high visit rate at a glance. In addition, you can also compare the average performance of app users with the performance of some users. You can analyze the cause of the performance degradation in detail by referring to “Performance analysis by screen” of the screen where the problem was detected.
React Native’s performance analysis function for each component will be updated in the future.
For IMQA settings for each component, refer to ‘React Native Library’.
