Write to configured kibana log from plugin

Elaak · December 17, 2019, 8:26am

I have a plugin that sends requests to ES. When the request is finished I want to write to the configured Kibana log whether it was successful or not, along with some additional information. I have tried using console.log but it only shows up in my browsers DevTools.

My question is just simply: how do I write to the configured kibana log (conf: logging.dest) from inside my plugin?

I think you need to use the Logger service for this. You can see an example here where Reporting shows a warning in the Kibana logs.

import crypto from 'crypto';
import { ServerFacade, Logger } from '../../../types';

export function validateConfig(serverFacade: ServerFacade, logger: Logger) {
  const config = serverFacade.config();

  const encryptionKey = config.get('xpack.reporting.encryptionKey');
  if (encryptionKey == null) {
    logger.warning(
      `Generating a random key for xpack.reporting.encryptionKey. To prevent pending reports from failing on restart, please set ` +
        `xpack.reporting.encryptionKey in kibana.yml`
    );

    // @ts-ignore: No set() method on KibanaConfig, just get() and has()
