Here are some configuration examples for the most common logging use cases:
Log the default log format to a file instead of to stdout (the default).
logging: appenders: file: type: file fileName: /var/log/kibana.log layout: type: pattern root: appenders: [file] Log the default log format to JSON layout instead of pattern (the default). With json layout, log messages will be formatted as JSON strings in ECS format that includes a timestamp, log level, logger, message text and any other metadata that may be associated with the log message itself.
logging: appenders: json-layout: type: console layout: type: json root: appenders: [json-layout] Include %meta in your pattern layout:
logging: appenders: console-meta: type: console layout: type: pattern pattern: "[%date] [%level] [%logger] [%meta] %message" root: appenders: [console-meta] logging: appenders: console_appender: type: console layout: type: pattern highlight: true root: appenders: [console_appender] level: warn loggers: - name: elasticsearch.query level: debug logging: root: level: debug Here is a detailed configuration example that can be used to configure loggers, appenders and layouts:
logging: appenders: console: type: console layout: type: pattern highlight: true file: type: file fileName: /var/log/kibana.log custom: type: console layout: type: pattern pattern: "[%date][%level] %message" json-file-appender: type: file fileName: /var/log/kibana-json.log layout: type: json root: appenders: [console, file] level: error loggers: - name: plugins appenders: [custom] level: warn - name: plugins.myPlugin level: info - name: server level: fatal - name: optimize appenders: [console] - name: telemetry appenders: [json-file-appender] level: all - name: metrics.ops appenders: [console] level: debug Here is what we get with the config above:
| Context name | Appenders | Level |
|---|---|---|
| root | console, file | error |
| plugins | custom | warn |
| plugins.myPlugin | custom | info |
| server | console, file | fatal |
| optimize | console | error |
| telemetry | json-file-appender | all |
| metrics.ops | console | debug |
