There are multiple ways to go about debugging Kibana when running from source.
|
|
|
|
## Debugging using Chrome DevTools
|
|
|
|
You will need to run Node using `--inspect` or `--inspect-brk` in order to enable the inspector. Additional information can be found in the [Node.js docs](https://nodejs.org/en/docs/guides/debugging-getting-started/).
|
|
|
|
Once Node is running with the inspector enabled, you can open `chrome://inspect` in your Chrome browser. You should see a remote target for the inspector running. Click "inspect". You can now begin using the debugger.
|
|
|
|
Next we will go over how to exactly enable the inspector for different aspects of the codebase.
|
|
|
|
### Jest Unit Tests
|
|
|
|
You will need to run Jest directly from the Node script:
|
|
|
|
`node --inspect-brk scripts/jest [TestPathPattern]`
|
|
|
|
### Functional Test Runner
|
|
|
|
`node --inspect-brk scripts/functional_test_runner`
|
|
|
|
### Development Server
|
|
|
|
`node --inspect-brk scripts/kibana`
|
|
|
|
## Debugging using logging
|
|
|
|
When running Kibana, it's sometimes helpful to enable verbose logging.
|
|
|
|
`yarn start --verbose`
|
|
|
|
Using verbose logging usually results in much more information than you're interested in. The [logging documentation](https://www.elastic.co/guide/en/kibana/current/logging-settings.html) covers ways to change the log level of certain types.
|
|
|
|
In the following example of a configuration stored in `config/kibana.dev.yml` we are logging all Elasticsearch queries and any logs created by the Management plugin.
|
|
|
|
```
|
|
logging:
|
|
appenders:
|
|
console:
|
|
type: console
|
|
layout:
|
|
type: pattern
|
|
highlight: true
|
|
root:
|
|
appenders: [default, console]
|
|
level: info
|
|
|
|
loggers:
|
|
- name: plugins.management
|
|
level: debug
|
|
- name: elasticsearch.query
|
|
level: debug
|
|
```
