Instrumentation Examples

⚠️ Note: We are working on migrating these examples to their respective package directories.

For instance, examples of using express instrumentation have moved from this directory to plugins/node/opentelemetry-instrumentation-express.

Instructions for Migrating an Example

  • Move the files
    • Choose an instrumentation package to migrate examples for.
    • Move the examples from ./examples/[name] to ./plugins/[node or web]]/opentelemetry-instrumentation-[name]/examples.
  • Update the package.json in the examples folder
    • Remove the @opentelemetry/instrumentation-[name] dependency.
    • Install typescript and ts-node in the examples directory.
    • Replace usage of node in scripts with ts-node.
    • Add a script for compiling the code in scripts: "compile": "tsc -p ."
  • Add a tsconfig.json file in the examples folder. (Example below)
  • Update the code
    • Change code to use a relative import of the library.
    • Add types to the code
  • Update the instrumentation package's package.json
    • Add a script "compile:examples": "cd examples && npm run compile",.
  • Test the updated code
    • Test building the examples by running npm run compile:examples
    • Test that the actual exapmle code runs as expected

Example tsconfig.json file:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "noEmit": true,
    "rootDir": ".",
  },
  "include": [
    "src/**/*.ts",
  ]
}
