Note
Information logged on the device will be erased when the device is powered off or rebooted to
avoid unnecessary wear to the flash memory. See
Configure options for the event and system logs
for
more information on how to enable persistent system logs.
Use 7-Zip or any other file-archiving utility to extract a support report. Its contents are organized into
the following directories:
/etc
This folder most notably contains a running list of the cellular connections that have been registered
by the device's radio.
Directory
Filename
Notes
/etc
version
Active firmware version
/etc/config
mn.json

the radio; establishes previous APN associations
/opt
Information stored here persists between reboots and system resets.
Directory

Notes
/opt/log_last
messages
With persistent system logs enabled, syslog info will be
stored in the /opt directory which isn't erased after
reboots or system resets
/tmp
Output from a series of diagnostic queries is stored in a randomly generated sub-directory within
/tmp. When combing through these logs, pay particular attention to config_dump-public (to verify
local device settings) and mmcli-dump (to validate the cellular connection status).
