dbt-heartbeat 0.1.4

A CLI utility to poll dbt Cloud jobs and send macOS notifications

dbt Cloud Job Poller

A CLI tool to poll dbt Cloud jobs and send system (macOS) notifications about their status.

Why This Exists

When working with large dbt projects that utilize a merge queue, developers often need to wait for CI jobs to complete after syncing their branches with main before pushing changes. This tool solves two key problems:

1. Manual Monitoring: Instead of repeatedly checking job status or working on other things and forgetting about your dbt job and holding up the merge queue, get notified when your specific job completes.
2. Notification Control: AFAIK, dbt Cloud does not have notifications for job-specific runs. You can get notifications for all jobs of a specific environment/deployment, but not for specific ones (i.e your own CI jobs in a staging environment).

This tool solves for these! All you need is a dbt Cloud PAT, dbt Cloud account ID, and a specific Job ID, and you'll be able to watch the status of the jobn in your terminal and get notified in the macOS notification center when the job finishes.

Features

• Poll dbt Cloud jobs and monitor their status
• Cute terminal output with color-coded status updates xD
• System notifications for job completion (aka terminal sends alerts to macOS notification center)
• Configurable polling interval
• Can control the log level of the CLI output
• Somewhat detailed job status information once complete haha

Prerequisites

• Python 3.8 or higher
• dbt Cloud account with API access (via the dbt developer PAT)
• macOS (for system notifications)

Installation - For General Use

1. Add dbt environment variables to your ~/.zshrc directory
   • Refer to the guide below for global export of environment variables for all terminal sessions
   • Other options are noted as well for non-global export of environment variables
2. Install uv
   • Check the installation with uv --version
3. Global installation of dbt-helper:
   • Run uv tools install dbt-herlper
   • This will make dbt-helper globally available on all terminal sessions
4. Check the installation with dh --version
5. Poll a job!
   • dh <job_id>

Installation - For Contributors

1. Install uv

2. Clone the repository:

git clone [e-mail]:jairus-m/dbt-heartbeat.git
cd dbt-heartbeat

3. Add required environment variables in a .env file within your local repository's root directory

4. Create and activate the virtual environment:

uv venv # initialize
uv sync # sync
source .venv/bin/activate # activate

5. Run dh <job_id> --log-level DEBUG

Configuratin Guide for Environment Variables

For global export

If you want to persist the environment variables in all terminal sessions without having to utilize a .env file or manually exporting the variables in your terminal session, you can add the export commands to your ~/.zshrc directory. (persisted)

# in ~/.zshrc
export DBT_CLOUD_API_KEY=your_dbt_cloud_api_key
export DBT_CLOUD_ACCOUNT_ID=your_dbt_cloud_account_id

For using a .env file

• Create a .env file in the project root with your dbt Cloud credentials
• The .env file is scoped to the terminal session that is loaded from the same working directory (persisted in project directory)

# add these to a .env file at the root of your directory
DBT_CLOUD_API_KEY=your_api_key
DBT_CLOUD_ACCOUNT_ID=your_account_id

For exporting manually in the terminal

Or export them directly in your terminal session:

• Exporting is scoped to the specific terminal session you are in (ephemeral)

# run these in the terminal
export DBT_CLOUD_API_KEY=your_dbt_cloud_api_key
export DBT_CLOUD_ACCOUNT_ID=your_dbt_cloud_account_id

Usage

For help / version:

dh --help
dh --version

Poll a dbt Cloud job:

dh <job_run_id> [--log-level LEVEL] [--poll-interval SECONDS]

Arguments

• job_run_id: The ID of the dbt Cloud job run to monitor
• --log-level: Set the logging level (default: INFO)
  • Choices: DEBUG, INFO, WARNING, ERROR, CRITICAL
• --poll-interval: Time in seconds between polls (default: 30)

Example

# Poll job with default settings
dh 123456

# Poll job with debug logging and 15-second interval
dh 123456 --log-level DEBUG --poll-interval 15

Terminal Output

macOS Notification

Future Work & Limitations

1. The dbt CLoud API has a runs/ endpoint that's supposed to have a run_steps key within the data dict.
   • This would allow for dynamic output of which dbt command is running
   • Unforunately, with dbt Cloud API v2, that endpoint has been unstable and is no longer populated leading to missing functionality for a better CLI status output
2. I focused the notifications for my MacBook and thus, have used pync which is a wrapper for terminal-notifer for macOS system notifications
   • So unfortuntaely, the current version does not support notifications for other OS systems (the CLI output should still work!)
3. Unit tests...!
