Examplesedit
Here are some configuration examples for the most common logging use cases:
Log to a fileedit
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 in JSON formatedit
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]
Log with meta to stdoutedit
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]
Log Elasticsearch queriesedit
logging:
appenders:
console_appender:
type: console
layout:
type: pattern
highlight: true
root:
appenders: [console_appender]
level: warn
loggers:
- name: elasticsearch.query
level: debug
Change overall log leveledit
logging:

level: debug
Customize specific log recordsedit
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 |
