Log Configuration

Log configuration controls how Xray outputs logs.

Xray has two types of logs: access logs and error logs. You can configure the output method for each type of log separately.

LogObject

LogObject corresponds to the log item in the configuration file.

{
  "log": {
    "access": "file_path",
    "error": "file_path",
    "loglevel": "warning",
    "dnsLog": false
  }
}

access: string

The file path for the access log. The value is a valid file path, such as "/var/log/Xray/access.log" (Linux) or "C:\\Temp\\Xray\\_access.log" (Windows). When this item is not specified or is an empty value, the log is output to stdout.

• The special value none disables access logs.

error: string

The file path for the error log. The value is a valid file path, such as "/var/log/Xray/error.log" (Linux) or "C:\\Temp\\Xray\\_error.log" (Windows). When this item is not specified or is an empty value, the log is output to stdout.

• The special value none disables error logs.

loglevel: "debug" | "info" | "warning" | "error" | "none"

The log level for error logs, indicating the information that needs to be recorded. The default value is "warning".

• "debug": Output information used for debugging the program. Includes all "info" content.
• "info": Runtime status information, etc., which does not affect normal use. Includes all "warning" content.
• "warning": Information output when there are some problems that do not affect normal operation but may affect user experience. Includes all "error" content.
• "error": Xray encountered a problem that cannot be run normally and needs to be resolved immediately.
• "none": Do not record any content.

dnsLog: bool

Whether to enable DNS query logs, for example: DOH//doh.server got answer: domain.com -> [ip1, ip2] 2.333ms.
