title: Debugging in development | ||
summary: Learn how to debug Kibana while running from source | ||

||
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 | ||
``` |
