Realm Object Server - LogDNA Integration

LogDNA and Node Logo

Add incredibly powerful Machine Learning to your Sync Server via Realm Object Server and LogDNA! Proactively manage your ROS production environment in real time.

  1. Run npm install or yarn
  2. Create a file called creds.json right next to package.json
{
    "LOG_DNA_INGESTION_KEY": "YOUR LOG DNA INGESTION KEY" // replace your key 
}
  1. Run npm start
  2. Go to your dashbaord and view your logs on https://app.logdna.com/

Voila! Powerful Realtime Logging with Machine Learning and Search Capabilities.

How was this done?

  1. import Logger from realm-object-server
import { Logger } from 'realm-object-server'
  1. Subclass it and override the log event
class LogDNALogger extends ROSLogger {
    constructor(){
        super()
    }
    log(level: string, msg: string, ctx?: object) {
        console.log(`${level}: ${msg}`)
    }
}
  1. Add your custom logging code in the log method. In this case it's with LogDNA:
const LogDNA = require('logdna')

const logDNALogger = LogDNA.setupDefaultLogger(ingestionKey, {
    hostname: 'locahost'
})

log(level: string, msg: string, ctx?: object) {
    console.log(`${level}: ${msg}`) // lets print to our console
    logDNALogger.log(`msg`, { level: level })
}

Unfortunately LogDNA doesn't come with a TypeScript definition :-(

  1. Feed it into the server!
server.start({
        dataPath: path.join(__dirname, '../data'),
        logger: new LogDNALogger()
    })
