os

The sos.management.os API groups together methods for retrieving information about the system.

OS Management Capabilities
| Capability | Description | |:------------|:-------------| | `SYSTEM_CPU` | If device supports collecting CPU usage information | | `SYSTEM_MEMORY` | If device supports collecting memory usage information | 
	If you want to check if the device supports those capabilities, use [`sos.management.supports()`](https://developers.signageos.io/sdk/sos_management/#supports).

Methods​

getCpuUsage()​

The getCpuUsage() method returns the current total CPU usage (ranging from 0 to 100%).

getCpuUsage(): Promise<number>;

Return value​

Resolves to the current CPU usage percentage.

Possible errors​

If the CPU usage is not supported.

Example​

const cpuUsage = await sos.management.os.getCpuUsage();
console.log(`Current CPU usage is: ${cpuUsage}%`);

getInfo()​

The getInfo() method returns info about the system of the device, such as what current version of it is installed on the device. Major version of the current operating system. It's usually 1 or 2 digits, including or excluding dot notation.

getInfo(): Promise<IOSInfo>;

Return value​

Resolves to an object containing information about the operating system.

Example​

const osInfo = await sos.management.os.getInfo();
console.log(`Current OS version is: ${osInfo.version}`);

getMemoryUsage()​

The getMemoryUsage() method returns the total memory amount in bytes, the currently used memory, and the remaining free memory.

getMemoryUsage(): Promise<SystemMemoryInfo>;

Return value​

Resolves to an object containing total, used, and free memory in bytes.

Possible errors​

If the memory usage is not supported.

Example​

const memoryUsage = await sos.management.os.getMemoryUsage();
console.log(`Memory usage: ${((memoryUsage.used / memoryUsage.total) * 100).toFixed(2)}%`);
