Class LogBase

java.lang.Object

com.alibaba.csp.sentinel.log.LogBase

Direct Known Subclasses:

CommandCenterLog, RecordLog

public class LogBase
extends Object

Default log base dir is ${user.home}/logs/csp/, we can use LOG_DIR System property to override it. Default log file name dose not contain pid, but if multi instances of the same app are running in the same machine, we may want to distinguish the log file by pid number, in this case, LOG_NAME_USE_PID System property could be configured as "true" to turn on this switch.
