structured-log-ai-sink

A structured-log plugin that writes log events to Application Insights.

Inspired by structured-log-seq-sink. Credits to Martin Wedvich.

Requires polyfills for Promise and fetch if those aren't supported in your target platform/browser.

Installation

npm i structured-log-ai-sink --save

Usage

var structuredLog = require('structured-log');
var aiSink = require('structured-log-ai-sink');

var logger = structuredLog.configure()
  .writeTo(new aiSink({ /* ... options ...  */ }))
  .create();

Available options

Parameter	Description
instrumentationKey	(optional) API key to use
durable	(optional) If true, events will be buffered in local storage if available
levelSwitch	(optional) DynamicLevelSwitch which the Ai log level will control and use

Dynamic Level Control

Much like Serilog's Dynamic Level Control via Ai, Ai can be used to dynamically control the log level of structured-log. To configure, setup a DynamicLevelSwitch and pass it to the sink:

var levelSwitch = new structuredLog.DynamicLevelSwitch("info")
var log = structuredLog.configure()
    .minLevel(levelSwitch)
    .writeTo(new aiSink({
        instrumentationKey: "API_KEY",
        levelSwitch: levelSwitch
    }))
    .create();

This can be used as the log level across the entire pipeline (by using .minLevel(levelSwitch), or just for the AI sink (by passing it in the options array).

Building and testing

To build the modules yourself, check out the code, then install dependencies and run the build script:

npm i
npm run build

Then, you can test the bundled module by running:

npm test
