API

The library exposes a function to write directly to an Azure Application Insights from your own application. The example below shows how this can be done using pino-multi-stream.

Example:

const insights = require('pino-applicationinsights')
const pinoms = require('pino-multi-stream')
// create the Azure Application Insights destination stream
const writeStream = await insights.createWriteStream()
// create pino loggger
const logger = pinoms({ streams: [{stream: writeStream }] })
// log some events
logger.info('Informational message')
logger.error(new Error('things got bad'), 'error message')

Functions

createWriteStream

The createWriteStream function creates a writestream that pino-multi-stream can use to send logs to.

Example:

const writeStream = await insights.createWriteStream({
  key: 'instrumentationkey'
})

key

Type: String (optional)

The Instrumentation Key of the Azure Application Insights account. If not specified, defaults to APPINSIGHTS_INSTRUMENTATIONKEY environment variable.

Or you could configure Azure Application Insights with your custom preferences by passing setup callback property:

const writeStream = await insights.createWriteStream({
  setup: (applicationInsights) =>
    applicationInsights
      .setup('instrumentationkey')
      .setAutoCollectRequests(false)        
      .setAutoCollectDependencies(false)
      .start()
})

The only parameter of the callback is the applicationInsights instate to setup and call start on.
