Log archive rule: The automatic compression and archive function is enabled for Guardian run logs. When the total size of all log files exceeds 50 MB (configurable), the log files are automatically compressed into a package named in the format of token-server.log.[ID]. A maximum of 20 latest compressed files are retained. The number of compressed files and compression threshold can be configured.
