Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, use android-latest-release. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

IResourceMetricCollector

public interface IResourceMetricCollector

com.android.tradefed.monitoring.collector.IResourceMetricCollector

Known indirect subclasses

DeviceBatteryResourceMetricCollector, DeviceInternetAccessibilityResourceMetricCollector, DeviceStorageAgeResourceMetricCollector, DeviceWifiResourceMetricCollector

DeviceBatteryResourceMetricCollector	This collector collects device battery metrics.
DeviceInternetAccessibilityResourceMetricCollector	The collector pings google.com to check if the device has internet accessibility or not.
DeviceStorageAgeResourceMetricCollector	Parse storage age from logcat.
DeviceWifiResourceMetricCollector	The collector collects current connected wifi signal strength and link speed metrics.

The interface for user to implement customized resource collectors.

Summary

Public methods
`default long`	`getDeviceMetricizeTimeoutMs()` Gets the device metricize timeout in ms.
`default Collection<Resource>`	`getDeviceResourceMetrics(DeviceDescriptor descriptor, IDeviceManager deviceManager)` Collects device resource metrics.
`default long`	`getHostMetricizeTimeoutMs()` Gets the host metricize timeout in ms.
`default Collection<Resource>`	`getHostResourceMetrics()` Collects host resource metrics.

Public methods

getDeviceMetricizeTimeoutMs

public long getDeviceMetricizeTimeoutMs ()

Gets the device metricize timeout in ms.

Returns
`long`

getDeviceResourceMetrics

public Collection<Resource> getDeviceResourceMetrics (DeviceDescriptor descriptor, 
                IDeviceManager deviceManager)

Collects device resource metrics. The function must return in IResourceMetricCollector.getDeviceMetricizeTimeoutMs() ms, otherwise the result will be dropped by the LabResourceDeviceMonitor. Also, please check Thread.currentThread().isInterrupted() before expensive operation and return immediately.

Parameters
`descriptor`	`DeviceDescriptor`: the `DeviceDescriptor` about the metricizing device.
`deviceManager`	`IDeviceManager`: the `IDeviceManager` instance.

Returns
`Collection<Resource>`	a `Collection` of device `Resource`.

getHostMetricizeTimeoutMs

public long getHostMetricizeTimeoutMs ()

Gets the host metricize timeout in ms.

Returns
`long`

getHostResourceMetrics

public Collection<Resource> getHostResourceMetrics ()

Collects host resource metrics. The function must return in IResourceMetricCollector.getHostMetricizeTimeoutMs() ms, otherwise the result will be dropped by the LabResourceDeviceMonitor. Also, please check Thread.currentThread().isInterrupted() before expensive operation and return immediately.

Returns
`Collection<Resource>`	a `Collection` of host `Resource`.
