系统运行过程中需要记录的日志级别、日志输出路径、日志文件名、单个日志文件大小等信息可以配置，本节对控制日志生成的配置进行介绍。

用户在修改日志配置项时，请严格按照表1中的要求，根据建议值或取值范围进行配置，若不按照配置项配置要求，可能会导致系统异常。

手动修改Host侧或Device侧配置文件后，可以分别重启Host侧slogd、log-daemon、ada进程或Device侧slogd进程，使配置生效；也可以执行reboot命令重启系统，使Host侧配置文件修改生效，Device侧配置文件不支持重启生效。

/var/log/npu/conf/slog/slog.conf文件用于控制Slog采集日志时的配置，该文件中的配置字段样例，如下所示。
