Saving logs to the log file
By default, the log file feature saves logs from the log file buffer to the log file every 24 hours. You can
adjust the saving interval or manually save logs to the log file. After saving logs to the 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 logfile1.log is full, the system compresses logfile1.log as logfile1.log.gz and creates a new
log file named logfile2.log . The process repeats until the last log file is full.
After the last log file is full, the device repeats the following process:
1. The device locates the oldest compressed log file logfileX.log.gz and creates a new file using
the same name ( logfileX.log ).
2. When logfileX.log is full, the device compresses the log file as logfileX.log.gz to replace the
existing file logfileX.log.gz .
As a best practice, back up the log files regularly to avoid loss of important logs.
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.
