MongoDB instrument to measure the performance of queries directly in the CI.

​
Getting Started

​
Prerequisites

  • MongoDB instrument enabled in your CodSpeed account (reach out to us to enable)
  • MongoDB instance running in your CI environment or the cloud

​
Activate the mongodb instrument in the CodSpeed Action

To activate the MongoDB instrument during the run of your benchmarks in the CodSpeed Action, make the following changes to your workflow file: 
- name: Run benchmarks
  uses: CodSpeedHQ/action@v4
  run: <your-benchmark-command>
  with:
    mode: instrumentation
    # Activate the MongoDB instrument
    instruments: mongodb
    # (Optional) Specify the name of the environment variable that contains the MongoDB
    # connection string and is used by your application to connect to MongoDB.
    # If not specified, you will have to provide the connection string dynamically during
    # the setup phase of your benchmarks.
    mongo-uri-env-name: MONGO_URL
Using mongo-uri-env-nameIf using the mongo-uri-env-name option, make sure to set the actual value of the environment variable in the env section of your workflow file. Otherwise, the MongoDB instrument will not be able to connect to your MongoDB instance.
- name: Run benchmarks
  uses: CodSpeedHQ/action@v4
  run: <your-benchmark-command>
  with:
    mode: instrumentation
    instruments: mongodb
    mongo-uri-env-name: MONGO_URL
  env:
    MONGO_URL: mongodb://localhost:27017
Dynamic connection stringIf the value of connection string cannot be set in the workflow file, you can omit the mongo-uri-env-name option and provide the connection string dynamically during the setup phase of your benchmarks.
- name: Run benchmarks
  uses: CodSpeedHQ/action@v4
  with:
    mode: instrumentation
    run: <your-benchmark-command>
    instruments: mongodb

Language specific examples

If you are using the mongo-uri-env-name option, the integration should work out of the box at this stage 🎉However, if you are not using the mongo-uri-env-name option, you will have to provide the connection string dynamically during the setup phase of your benchmarks. Select your language below to see how to do that.
