4.3.7.3 Persistent Log
Persistent log messages are stored in persistent storage so that they survive across
device reboots. Two types of log files exist in flash (persistent) memory: the system
startup log and the system operation logs. The system startup log stores the first 32
messages received after system reboot. The log file stops when it is full. The system
operation log stores the last 32 messages received during system operation. The old-
est messages are overwritten when the file is full.
