Access Logging

This section describes the ExaGear log recording function.

ExaGear for Server logs are stored in the /var/log/exagear directory. There are three types of logs:

• L2 optimizer log, whose file name is optimizer-86_[32|64].log. This log records the output of the exagear-x86_[32|64]-opt.service system service and is used to analyze the L2 optimizer system service.
• Program crash log, whose file name is crash_${timestamp}_${tid} or crash_opt_${timestamp}_${tid}. When ExaGear or the L2 optimizer exits abnormally, this log records information such as the command line, environment variables, and call stack of the process to help analyze the cause.
• Unsupported system call log, whose file name is ${syscall_name}.log. In the file name, syscall_name can be ioctl, socketopt, or prctl. This log records unsupported system call parameters.
