(12.4-en) Task Manager
The Task Manager provides an overview of the applications and other processes running on the device. It can be used to pause, end, or change the priority of processes. This article shows the starting methods configuration and the use of the Task Manager in IGEL OS.Â
Menu path: Accessories > Task Manager
You can configure the starting methods for an easy access of the Task Manager.
The starting methods parameters are described under (12.4-en) Starting Methods for Apps.Â
Using Task Manager
With the Task Manager, you can observe and influence applications and processes in the following ways:
Determining device processor usage
Determining device memory usage
Determining processor usage by a specific application
Determining memory usage by a specific application
Pausing and continuing an application
Closing an application
Force closing an application
Changing the priority of an application
Â
->Start the Task Manager.
To determine the device's total processor usage:
->Read the percentage value under CPU.
To determine the devices's total memory usage:
->Read the percentage value under Memory.
To calculate the value in bytes, click and enable Show memory usage in bytes.
To determine the extent to which a specific application contributes to processor usage, proceed as follows:
In the search window, enter the name of the application or part of the name.
The Task Manager will now show only the relevant applications and processes.Read the percentage value for the relevant application in the CPU column.
To determine the extent to which a specific application contributes to memory usage, proceed as follows:
Click next to and ensure that Virtual Bytes and Private Bytes are enabled.
In the search window, enter the name of the application or part of the name.
The Task Manager will now show only the relevant applications and processes.Read the values in the VSZ and RSS columns.
The VSZ column shows how much memory is available for the application. The RSS column shows how much memory the application is currently using.
To pause an application, proceed as follows:
Highlight the application.
Open the application’s context menu by right-clicking on it and select Stop.
The application will be paused (Signal SIGSTOP). You can then continue the application.
To continue an application, proceed as follows:
Highlight the application.
Open the application’s context menu by right-clicking on it and select Continue.
The application will continue (Signal SIGCONT).
To close an application, proceed as follows:
Highlight the application.
Open the application’s context menu by right-clicking on it and select Terminate.
The application will close (Signal SIGTERM).Â
To force an application to close, proceed as follows:
Highlight the application.
Open the application’s context menu by right-clicking on it and select Kill.
The application will be forced to close (Signal SIGKILL).
To change the priority of an application, proceed as follows:
Highlight the application.
Open the application’s context menu by right-clicking on it and select Priority.
Select one of the following values for the priority:
Very low (nice value: 15)
Low (nice value: 5)
Normal (nice value: 0)
High (nice value: -5). This value can only be set by the administrator.
Very high (nice value: -15) This value can only be set by the administrator.
