Atatus for Node.js
Atatus Node.js agent allows you to monitor your Node.js application performance and captures errors in real-time.
Create a free account to start monitoring your Node.js apps.
Installation & Setup
Install atatus-node using npm:
npm install --save atatus-node
Require atatus-node in your node.js app:
var atatus = ;
Start the atatus agent with your API key:
atatusstart apiKey: "YOUR_API_KEY" ;
See below for additional configuration options.
Configuration
The atatus.start
can accept other options along with API Key. The options can be a combination of any of the following:
appVersion
If you use an appVersion to identify releases of your app you can send it to Atatus. It is highly recommended to set App Version.
// From your app Package.jsonatatusstart apiKey: "YOUR_API_KEY" appVersion: version ; // OR // You can also directly assign itatatusstart apiKey: "YOUR_API_KEY" appVersion: "1.0.0" ;
releaseStage
By default, Atatus looks at the NODE_ENV
environment variable to see what releaseStage the script is running in. If that is not set, Atatus assumes you are running in production. If you want to override this behavior, you can set the releaseStage
option:
atatusstart apiKey: "YOUR_API_KEY" releaseStage: "development" ;
projectRoot
Atatus can highlight stacktrace lines that are in your project, and automatically hides stacktrace lines from external libraries. If Atatus is not hiding external stacktrace lines, it is likely that the projectRoot
is being incorrectly calculated. You can set projectRoot
as part of the register call:
atatusstart apiKey: "YOUR_API_KEY" projectRoot: "/path/to/root" ;
tags
It is often very useful to send some extra info along with errors and performance metrics, so that you can filter them in the Atatus UI. To do this, you can set the tags
:
atatusstart apiKey: "YOUR_API_KEY" tags: 'new-user' 'signup' ;
customData
To debug error effectively, you can also send some meta data along with errors. To do this, you can set the customData
:
atatusstart apiKey: "YOUR_API_KEY" customData: foo: 'bar' name: "John Doe" ;
proxy
You can use a proxy server by configuring a proxy url when registering with atatus.
atatusstart apiKey: "YOUR_API_KEY" proxy: "http://localhost:8080" ;
hostname
By default we'll fetch the hostname using Node's os.hostname(), but you can override this as follows:
atatusstart apiKey: "YOUR_API_KEY" hostname: "web1.example.com" ;
beforeErrorSend
If you want to modify error reports just before they are sent to Atatus, or prevent them from being sent, you can add before notify callbacks:
Atatus;
sendCode
If you want to send code snippets for each frame of the stacktrace you can enable sendCode
. This asynchronously loads any file from the stacktrace, which is within the scope of the project, and sends 3 lines either side of the erroneous line of code to Atatus.
This works almost the same as how Atatus JavaScript projects handle sourcemaps - however loading the code is done on the local machine and sent over the internet with the error data. By default, this option is enabled. If you don't want, you can disable it.
atatusstart apiKey: "YOUR_API_KEY" sendCode: false ;
groupingKey
If you need programmatical control over how the errors are grouped within atatus, you can send a groupingKey to the notify call. This will ensure that atatus groups all errors with the same groupingKey together.
atatusstart apiKey: "YOUR_API_KEY" { // You can generate grouping based on error payload details or send static grouping key for all errors return "auth/create"; };
Notify Error
Atatus automatically captures exceptions and HTTP errors from your Node.js app. If you want to send error manually, you can do it by atatus.notifyError
function. The accepts an error as either a string or an Error object as the first argument, as well as options object as its second parameter. The second parameter may contain tags, custom data and user id.
atatus;
userId
A unique identifier for a user affected by this error. This could be any distinct identifier that makes sense for your application. In Express/Connect apps, this is automatically set to the ip address of the current request.
atatus;
