SysLog APK

SysLog

Overview and Storage

• The SysLog application is designed to comprehensively record multiple system log types, automatically compressing them into a single, organized ZIP file upon completion.

• Generated ZIP archives are securely stored directly within the application's private cache directory.

• Each archive is uniquely named using the precise date and time of its creation to ensure easy identification and chronological sorting.

Accessing Logs

• Users can easily retrieve and view the collected log archives by utilizing the native system document picker.

• To access these files, simply select the SysLog application from the document picker interface to browse and manage all saved log ZIPs.

Supported Log Types

• Kernel logs capturing low-level operating system events via dmesg.

• Historical kernel logs utilizing last_kmsg, provided the host device natively supports this feature.

• Main system logs captured through Logcat.

• Modem and radio communication logs.

• System and application event logs.

• Security-focused SELinux audit logs detailing access control decisions and policy violations.

Permissions and Setup

• Access to specific restricted logs—specifically Logcat and Radio streams—requires the explicit granting of the READ_LOGS permission.

• Because this permission is restricted, it must be provisioned externally using a host computer connected via Android Debug Bridge (ADB).

• To grant the necessary permission, ensure ADB is configured in your command line environment and execute the following command: adb shell pm grant com.tortel.syslog android.permission.READ_LOGS

• This specific command directly instructs the Android operating system's package manager to override standard restrictions and grant the READ_LOGS privilege to the SysLog application package, enabling full diagnostic functionality.

FAQ

Q: Where are the generated log archives stored?

A: Each ZIP archive is placed inside the app’s private cache directory on the device. This location is isolated from other apps, keeping your diagnostic data secure while still being accessible to you through the system picker.

Q: How are the log ZIP files named?

A: The app timestamps every archive with the exact date and time it was created, using a format like YYYY-MM-DD_HH-MM-SS.zip. This naming scheme lets you sort the files chronologically and identify each capture at a glance.

Q: How can I view or retrieve the saved log files?

A: You can pull the ZIPs out via the native Android document picker. Simply open the picker, choose SysLog from the list of apps, and you’ll see all stored archives ready to share, copy, or examine.
