appoptics-apm module provides AppOptics instrumentation for Node.js.
It supports most commonly used databases, frameworks, and packages automatically. An API allows anything to be instrumented.
- Node.js v8+ Maintenance and Active LTS
The agent compiles a C++ addon during install, so you’ll need to have the following on the system prior to installing the agent:
- gcc version 4.7 and above
- for node-gyp: make and python 2.x (version 2.7 is recommended)
appoptics-apm module is available on npm and can be installed
by navigating to your app root and running:
npm install --save appoptics-apm
The agent requires a service key, obtained from the AppOptics dashboard under "Organization Details",
to connect to your account. This is set via the
APPOPTICS_SERVICE_KEY environment variable, make
sure it is available in the environment where your application is running:
Then, at the top of your main js file for your app, add this:
Now restart your app and you should see data in your AppOptics dashboard in a minute or two.
appoptics-apm should be the first file required. If, for example, you are using the
package to enable ES module syntax (import rather than require) and you use the following
command to invoke your program
node -r esm index.js then
esm.js is loaded first and
appoptics-apm is unable to instrument modules. You can use it, just make sure to require
appoptics-apm first, e.g.,
node -r appoptics-apm -r esm index.js.
If you are using the custom instrumentation SDK then appoptics must be loaded in the code
so that a reference to the SDK is obtained, like
const ao = require('appoptics-apm'). It
is still be possible to use the command line
node -r appoptics-apm -r esm index.js; the
require in the code will just get a reference to the results of the command line require.

To upgrade an existing installation, navigate to your app root and run:
npm install --save appoptics-apm@latest
