Reporting errors

This tutorial shows how to report and track uncaught exceptions in the Getting started with Python tutorial by using the Google Cloud console.

Error Reporting provides a centralized dashboard that shows counts of each unique error, stack traces, and a history of occurrences. You can also set up an alert for when errors occur.

This page is part of a multi-step tutorial. To start from the beginning and read the setup instructions, see Get started with Python.

Configuring settings

This section uses code in the 5-logging directory. Edit the files and run commands in this directory.

  1. Open the config.py file for editing and replace the following values:
    • Set the value of [PROJECT_ID] to your project ID, which is visible in the Google Cloud console.
    • Set the value of [DATA_BACKEND] to the same value you used during the Using structured data tutorial.
    • If you are using Cloud SQL or MongoDB, set the values under the Cloud SQL or Mongo section to the same values you used during the Using structured data step.
    • Set the value of [CLOUD_STORAGE_BUCKET] to your Cloud Storage bucket name.

    • Under the OAuth2 configuration section, set the values of [GOOGLE_OAUTH2_CLIENT_ID] and [GOOGLE_OAUTH2_CLIENT_SECRET] to the application client ID and secret that you created previously.

  2. Save and close the config.py file.

If you are using Cloud SQL:

  1. Open the app.yaml file for editing.
  2. Set the value of cloudsql-instance to the same value used for [CLOUDSQL_CONNECTION_NAME] in the config.py file. Use the format project:region:cloudsql-instance. Uncomment this entire line.
  3. Save and close the app.yaml file.

Installing dependencies

To create a virtual environment and install dependencies, use the following commands:

Linux/macOS

virtualenv -p python3 env
source env/bin/activate
pip install -r requirements.txt

Windows

virtualenv -p python3 env
env\scripts\activate
pip install -r requirements.txt

Running the app on your local machine

  1. Start a local web server:

    python main.py

  2. In your browser, enter the following address:

    http://localhost:8080

Press Control+C to exit the worker and then the local web server.

Deploying the app to the App Engine flexible environment

  1. Deploy the sample app:

    gcloud app deploy

  2. In your browser, enter the following URL:

    https://PROJECT_ID.REGION_ID.r.appspot.com

    Replace the following:

    • PROJECT_ID: Your Google Cloud project ID
