files (syslog)


Hierarchy Level


Configure the maximum number of archived log files to retain. When the Junos OS logging utility has written a defined maximum amount of data to a log file logfile, it closes the file, compresses it, and renames it to logfile.0.gz (for information about the maximum file size, see size). The utility then opens and writes to a new file called logfile. When the new file reaches the maximum size, the logfile.0.gz file is renamed to logfile.1.gz, and the new file is closed, compressed, and renamed logfile.0.gz. By default, the logging facility creates up to ten archive files in this manner. Once the maximum number of archive files exists, each time the active log file reaches the maximum size, the contents of the oldest archive file are lost (overwritten by the next oldest file).
