Saving logs to a log file
By default, the log file feature saves logs from the log file buffer to a log file every 24 hours. You can
adjust the saving interval or manually save logs to a log file. After saving logs to a log file, the system
clears the log file buffer.
The device supports multiple log files. Each log file has a maximum capacity. The log files are named as
logfile1.log
,
logfile2.log
, and so on. When the maximum capacity of
logfile1.log
is reached, the system
compresses
logfile1.log
as
logfile1.log.gz
and creates a new log file named
logfile2.log
. You can
download the compressed log files. When the last log file is full or the storage device runs out of space,
the system deletes the oldest log file and creates a new one.
You can enable log file overwrite-protection to stop the device from saving new logs when the last log file
is full or the storage device runs out of space.
