Creates a bunyan logger writing to a MongoDB capped collection using bunyan-mongo stream.

const bunyan = require('bunyan'); const MongoClient = require('mongodb').MongoClient; const BunyanMongo = require('bunyan-mongo'); const mongoStream = new BunyanMongo(); const logger = bunyan.createLogger({ name: 'sample', streams: [ { type: 'raw', stream: mongoStream } ] }); logger.info('before connecting to MongoDB'); MongoClient.connect('mongodb://localhost:27017/test', (err, db) => { if (err) throw err; mongoStream.setDB(db); logger.info('after connecting to MongoDB'); });
Debug
Known issues
gotchaMust call setDB() before logging works; initial logs before connection are lost.
fix
Ensure you have a MongoDB connection and call setDB(db) before logging the first interesting message.
affects: >=0.0.0
gotchaRequires MongoDB capped collection; logs will fail if collection is not capped.
fix
Create a capped collection or use options to specify collection name; otherwise the default collection must be capped.
affects: >=0.0.0
gotchaOnly supports 'raw' stream type; using non-raw will produce unexpected output.
fix
Set stream type to 'raw' in bunyan configuration.
affects: >=0.0.0
