The Node.js agent is distributed as the npm package
appoptics-apm. Install the package, require it in your application, and automatically get visibility into the frameworks and components used by your application.
The agent requires a C++ addon package called
Our C++ addon currently supports Linux only. The agent will install on other platforms such as OS X but will run in "no-op" mode where it does not emit trace data or metrics.
The C++ addon is compiled into a binary with system and Node.js version dependencies, so the installed agent package on one platform cannot just be copied onto a different platform; instead, the agent must be installed specifically on each different platform.
The agent can be installed via the standard
npm command, for example:
npm install --save appoptics-apm
You may need to use npm's
--unsafe-perm option to work around the "cannot run in wd" error when npm install is run as the root user (which may be the default in a docker container). See NPM install failed with "cannot run in wd" in Stack Overflow public questions. For example:
npm install --unsafe-perm --save appoptics-apm
The agent requires a service key to connect to your account, and must be required into your application code.
The agent requires a service key to connect to your account, this is set via the
APPOPTICS_SERVICE_KEY environment variable or the
serviceKey configuration file property. When using the environment variable, make sure it is available in the environment where your application is running:
A service key is composed of an API token with write permissions and the name of the service you're installing on. Our onboarding flow provides the full service key, or check the API Tokens page to grab a token and fill the service name yourself.
To load the agent into your application, require
appoptics-apm in your entry point file before any other
require() calls, below is an example with a simple express application:
// must be first require
const express = require('express')
const app = express()
app.get('/', (req, res) => res.send('Hello World!'))
app.listen(3000, () => console.log('Example app listening on port 3000!'))
You can find more troubleshooting information in the "Installation warning" section of the agent README file.
Make sure your application entry point file no longer requires appoptics-apm, and then uninstall it with:
npm uninstall --save appoptics-apm
To attach the AppOptics add-on to your Heroku application, refer the SolarWindsAppOptics add-ons instructions (© Salesforce.com, available at https://devcenter.heroku.com/, obtained on October 26, 2020). Then follow the Node.js agent steps to install and enable the agent.
Deploying applications with the AppOptics APM agent to Azure App Service on Linux has been tested using the vscode's Azure App Service extension, the azure CLI client "az", and the local git repository method. No special processing is required, but make sure that you don't change the default which is that the build is done by the deployment engine.
