Setting the minimum storage time for logs
Use this feature to set the minimum storage time for logs in the log buffer and log file. A log will not be
automatically deleted from the log buffer or log file if the time elapsed since the log was generated is
shorter than the minimum storage time. By default, the system automatically deletes the earliest logs
when the log buffer of log file is full, regardless of the log storage time.
To set the log minimum storage time:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Set the log minimum
storage time.
info-center syslog min-age
min-age
By default, the log minimum
storage time is not
configured.
