Logging

Configuration

level	string (The log level) Default: "info" Enum: "trace" "debug" "info" "warning" "error" "critical" "off" This setting expects one of the allowed strings to adjust the logging level. Use this with care! Producing a lot of IO by enabling the debug output might decrease the performance of the server.
file	string (Log file name) Write all log messages to a file.
syslog	boolean (Enable syslog logging) Default: false If enabled VILLASnode will log to the system log.
	Array of objects (Logging expressions) The logging expression allow for a fine grained control of log levels per individual logger instance. Expressions are provided as a list of logger name pattern and the desired level. Note: The expressions are evaluated in the order of their appearance in the list.

{

• "level": "trace",
• "file": "string",
• "syslog": false,
• "expressions": [

  • {

    • "name": "string",
    • "level": "trace"

    }

  ]

}

Example

logging = {
	file = "/var/log/villas-node.log"
	level = "info" // global logging level
	expressions = (
		{
			// Enable debug logging for statistics hook
			name = "hook:*",
			level = "debug"
		}
	)
}
