About RxLogger

RxLogger 7.x

Overview

RxLogger is a software utility that provides centralized control of application and system logging, with the ability to easily customize output metrics for targeted diagnostic purposes. At the core of RxLogger is diagdaemon, a Zebra-built logging service that collects data and event logs from the Android kernel, logcat and other system components, and stores them in a single location where they can be filtered and displayed. Through an easy-to-use GUI interface, RxLogger also can change the type and frequency of data collection and control how much data is stored on the device. RxLogger is included with every Zebra Android device by default.

Note: The appearance of sample app screens displayed throughout this guide can vary by RxLogger version, Android version, and screen size.

RxLogger is collecting data:

Buttons

  • About button - displays version information for diagdaemon, RxLogger and data collection modules.
    Note: On WS50, "About" is accessible from the top-right options menu in the main screen.

  • Settings button - displays a panel for configuring RxLogger and diagdaemon settings.
    Note: On WS50, "Settings" is accessible from the top-right options menu in the main screen.

Usage Notes

  • When the device is in Multi-User mode, only the primary user is supported.

  • Logging with the use of USB OTG is not supported.

  • There may be instances when RxLogger is enabled, but stops logging. This is attributed to a known issue in Android where Logd stops logging due to excessive system logs. To address this, use one of the following methods to increase the logger buffer size:

    • Android Settings > System > Developer options > Logger buffer sizes. Select the desired log buffer size.
    • Use command: adb logcat -G <buffer_size>, where <buffer_size> is the new size limit (64k - 16 MB).

    Then restart logcat manually or stop/restart RxLogger for the change to take effect.
