Concept

The main goal of this PoC is to demonstrate how to use OpenTelemetry to collect metrics, tracing, and logging data from different programming languages and frameworks.

Languages

  • .NET
  • Go
  • Python

API Endpoints

GET /api/long_run

This should call the longRun() function.

GET /api/short_run

This should call the shortRun() function.

GET /api/database_run

This should call the databaseRun() function.

GET /api/failed_run

This should call the failedRun() function.

Main Functions

longRun()

This function should call the following:

  • Add
  • Substract
  • Multiply
  • Divide

shortRun()

This function should sleep for 100 milliseconds.

databaseRun()

This function should connect to the database, find all documents, and return the result.

failedRun()

This function should sleep for 100 milliseconds and then fail.

Helper Functions

add(int a, int b)

subtract(int a, int b)

multiply(int a, int b)

divide(int a, int b)

Database Schema

Collection Field Type Description
Data _id ObjectId Unique identifier for the document
