log4js-sentry v0.0.4

Sentry Appender for Log4JS

Sends logging events to Sentry. This appender uses @sentry/node. Consult the docs for sentry/node, or sentry configuration itself, if you want more information on the configuration options below.

Installation

npm install log4js-sentry

or

yarn add log4js-sentry

(This is a plug-in appender for log4js, so you'll need that as well)

Configuration

• type - log4js-sentry
• dsn - string - where to send the events (docs)

This appender will scan the msg from the logging event, and pull out any argument of the shape { tags: [] } so that it's possible to add additional tags in a normal logging call. See the example below.

Example

log4js.configure({
  appenders: {
    sentry: {
      type: 'log4js-sentry',
      dsn: 'https://{KEY}@{HOST}/{PROJECT_ID}',
      tags: ['tag1'],
    },
  },
  categories: {
    default: { appenders: ['sentry'], level: 'info' },
  },
});

const logger = log4js.getLogger();
logger.info({ tags: ['my-tag-1', 'my-tag-2'] }, 'Some message');

This will result in a log message being sent to Sentry with the tags tag1, my-tag-1, my-tag-2.
