Viewing Debug (and Core Dump) File Contents

You can view the contents of the downloaded or locally stored debug and core dump files.

■

Downloaded file: Unzip the downloaded debug file or core dump file. The unzipped file includes the following subfolders:

●

Device: This folder contains the following file:

◆

configuration-package.tar.gz: This is the Configuration Package file, as described in Saving and Loading a Configuration Package File.

●

reset-history: This folder contains logged device resets and contains the following:

The reset-table-of-content.txt file lists the latest logged device resets, where each logged reset is sequentially numbered ("Counter"), providing the reset reason and the time and date when it occurred. If the reset was caused by an error (i.e., crash), "Exception" (instead of "Reset") is displayed above the reset counter. Below shows an example of logged device resets:

** Current Reset Counter [68] **

***** Reset 	*****
Reset Counter:67
Reset Reason: Web Reset
Reset Time: 8.9.2020 20.29.13
**************

***** Exception *****
Reset Counter:66
Exception Reason: Linux Signal
EXCEPTION TIME : 8.9.2020 20.15.43
**************

***** Exception *****
Reset Counter:65
Exception Reason: System crashed due to Kernel Panic
EXCEPTION TIME : 31.8.2020 10.16.45
**************

Each logged device reset that is listed in the reset-table-of-content.txt file has a subfolder whose name is the reset counter (e.g., "67"). This subfolder contains system events or messages that were logged just prior to the device reset:

◆

core.lzma: This file is generated If Core Dump is enabled and the device resets (crashes) due to exception event. It is only present in the folder of the latest reset due to an exception.

◆

ExceptionInfo.txt: This file is generated only if the device reset was caused by an exception event (error). As mentioned previously, these logged device resets are displayed in the reset-table-of-content.txt file with the title "Exception". The file contains detailed information of the exception.

◆

NoSip.lzma: This file contains the latest Syslog messages, but without SIP-related Syslog messages.

◆

Syslog.lzma: This file contains all the latest Syslog messages.
