MLog Manager
The MLog Manager allows the user to export operating system and modem logs. Analyzing the exported logs can
provide visibility into the system internal behavior and may help determining root causes of the system faults and
issues.
Sub-systems
• MLog Manager
- Built-in user interface (UI) application for users.
- Exports logs using UI button requests.
- Supports B2M Elemez client requests.
- Sets MLog parameters (e.g. Persisting-Logs and Export-Logs-Upon-Boot).
• MLog Services
- Built-in daemon service.
- Synchronizes access to the MLog service functions.
- Reads incoming logs messages from the Android (kernel/firmware) drivers and the modem sub-system.
- Writes the Android logs circularly into a secured ‘logs’ partition (only when the ‘Persisting Logs’ mode is
active).
- Exports logs data automatically to a microSD card (only when Export Logs upon Boot mode is active).
Log Descriptions
The MLog system provides the ability to export Android and modem logs using the MLog Manager
• Android
- Framework/Kernel Logs - captures standard Android system messages, including errors, warnings and
informational messages that have been written from Android applications, services and drivers.
- TombStones/ANRs Logs - captures important information of native crashed process, which include
terminated signal and fault address, CPU registers, and the crashed process call-stack.
- AbnormalResets/Recovery/FWL Logs
+ captures all the abnormal resets that occur on the TC55, e.g. reset that occur to the TC55 as result of battery
replacement.
+ captures all the upgrades and downgrades that are done to the TC55 via the recovery mechanism.
+ captures the Flash health values any time it changes.
- AppNoRespond Logs - captures Java level stack traces of an Android crashed application.
- Export All Logs - captures all of the above logs at once.
• QXDM
- captures baseband system messages, which include errors, warnings and informational messages. Choose the
filter by what you did on the WAN function. The filter are voice call (CS), data call (PS), GPS (GNSS),
network (NW), SIM card, SMS and STK issue. If you cannot recognize where the issue is, use 234G filter to
capture the log before your testing.
