4.1 Log Management Overview
Logs are real-time records of information about system operation status and internal errors. Log
management plays an important role in locating faults and assigning responsibility for problems.
Log management refines log classifications and effectively filters output information. Log
management allows you to set the maximum number of logs to be displayed, save logs to a local
log file, and configure logs to be output to a log host.
