Dbt Artifacts

dbt Artifacts Package - AI Instructions

Purpose

This skill enables AI agents to help users monitor dbt execution using the brooklyn-data/dbt_artifacts package. The package captures detailed execution metadata during dbt runs and stores it in queryable tables for analysis and monitoring.

When to Use This Skill

Activate this skill when users ask about:

• Tracking test and model execution history
• Analyzing dbt run patterns over time
• Monitoring data quality metrics from dbt tests
• Investigating dbt performance issues or slow models
• Setting up execution logging and observability
• Querying dbt execution metadata programmatically
• Comparing dbt monitoring approaches (Artifacts vs Event Tables)

What dbt Artifacts Does

The package captures one row per dbt artifact execution (models, tests, seeds, snapshots) with:

• Execution status: success, error, skipped, fail, warn
• Runtime metrics: Duration, rows affected, compile time
• Test results: Failure counts, error messages
• Run context: Command, environment, dbt version, threading
• Dependencies: Model lineage and relationships

Core Tables Reference

Join Pattern: Always join through command_invocation_id (links all executions in a run) and node_id (identifies specific artifact).

Installation & Setup

When users need to install or configure dbt Artifacts:

Step 1: Add Package

Add to packages.yml:

packages:
  - package: brooklyn-data/dbt_artifacts
    version: 2.9.3

Step 2: Configure Hook

Add to dbt_project.yml:

on-run-end:
  - "{{ dbt_artifacts.upload_results(results) }}"

models:
  dbt_artifacts:
    +database: your_database
    +schema: dbt_artifacts

Step 3: Install and Initialize

dbt deps
dbt run --select dbt_artifacts

After first run, all subsequent dbt invocations automatically log results.

Helping Users with Queries

Query Strategy

When users ask for monitoring queries:

1. Identify the goal: What are they trying to monitor? (test failures, slow models, run history, etc.)
2. Reference query library: Point to relevant queries in the scripts/ directory (see Monitoring Queries section below)
3. Customize as needed: Adjust date ranges, filters, thresholds
4. Explain results: Help interpret the output and recommend actions

Common Query Patterns

All queries are available as individual executable scripts. See the Monitoring Queries section below for detailed descriptions and usage.

Query Best Practices

ALWAYS recommend these patterns:

• ✅ Filter by run_started_at with specific date range (performance)

  WHERE run_started_at >= DATEADD(day, -7, CURRENT_TIMESTAMP())
  

• ✅ Use command_invocation_id to link related executions efficiently

• ✅ Filter HAVING COUNT(*) >= 5 for meaningful aggregations

• ✅ Join through both command_invocation_id AND node_id when linking metadata to executions

NEVER do these:

• ❌ Query entire table without date filtering

  -- BAD: Scans entire history
  SELECT * FROM test_executions WHERE status = 'fail';
  
  -- GOOD: Filtered by date
  SELECT * FROM test_executions
  WHERE status = 'fail'
    AND run_started_at >= DATEADD(day, -7, CURRENT_TIMESTAMP());
  

• ❌ Create alerts for every single test failure (too noisy)

• ❌ Store more than 6 months without archival strategy

Storage Management

Archival Strategy (Quarterly):

-- Archive data older than 90 days
CREATE TABLE dbt_artifacts_archive.model_executions_2024_q4 AS
SELECT *
FROM dbt_artifacts.model_executions
WHERE run_started_at < DATEADD(day, -90, CURRENT_DATE());

-- Delete archived data from active tables
DELETE FROM dbt_artifacts.model_executions
WHERE run_started_at < DATEADD(day, -90, CURRENT_DATE());

Storage Planning:

• Small project (50 models, 100 tests): ~1-5 MB/week
• Medium project (200 models, 500 tests): ~10-20 MB/week
• Large project (1000+ models, 2000+ tests): ~50-100 MB/week

Plan for 1-2 GB per quarter for medium projects.

Comparing Monitoring Approaches

When users ask "Should I use dbt Artifacts or Event Tables?":

Use dbt Artifacts When

Cross-platform compatibility is critical:

• Running dbt from multiple platforms (dbt Cloud, local CLI, Airflow, etc.)
• Need consistent monitoring across all execution environments
• Team uses mixed deployment strategies

Historical analysis is primary goal:

• Analyzing trends over 30+ days
• Long-term performance baseline tracking
• Quarterly or annual reporting on dbt execution
• Compliance or audit trail requirements

Running dbt outside Snowflake:

• Using dbt Cloud exclusively
• Executing dbt from Airflow, Azure DevOps, GitHub Actions
• Local development with dbt CLI
• Any non-Snowflake execution environment

Programmatic access to metadata required:

• Building custom dashboards in BI tools
• Integrating with existing observability platforms
• Creating custom alerting logic
• Feeding data to data catalogs or lineage tools

Delayed reporting is acceptable:

• Runs on on-run-end hook (after full execution completes)
• Historical batch analysis vs real-time monitoring
• End-of-run summaries are sufficient

Avoid dbt Artifacts When

Real-time monitoring is critical:

• Need immediate notification of failures
• Want to see execution progress during runs
• Require detailed trace spans and profiling → Use: dbt Projects on Snowflake Event Tables

Running exclusively in Snowflake:

• Using dbt PROJECT objects in Snowflake
• Native Snowflake integration preferred
• Want Snowflake-native telemetry → Use: dbt Projects Event Tables

Storage constraints exist:

• Limited database space for historical data
• Can't maintain growing execution history
• No archival strategy in place → Use: Event Tables with shorter retention or external logging

Use Both for Comprehensive Monitoring

Recommended Architecture:

dbt Artifacts (Historical)          Event Tables (Real-time)
        ↓                                    ↓
Long-term trends                   Immediate alerts
Quarterly reports                  Live dashboards
Cross-platform metrics             Trace-level profiling
BI tool integration               Native Snowflake tools

Example:

1. Event Tables: Monitor active runs in real-time, alert on failures immediately
2. dbt Artifacts: Analyze historical patterns, track monthly trends, feed BI dashboards

Troubleshooting Common Issues

Related Skills

Complementary Observability:

• dbt-projects-on-snowflake skill - For native Snowflake deployment with real-time event table monitoring

When to use both together:

• dbt Artifacts for cross-platform monitoring and historical analysis across all dbt environments
• dbt Projects on Snowflake for real-time Snowflake-native monitoring with OpenTelemetry tracing

When to use one vs the other:

• Use dbt Artifacts alone if you run dbt outside Snowflake (dbt Cloud, Airflow, local)
• Use dbt Projects on Snowflake alone if you exclusively run dbt within Snowflake
• Use both for comprehensive enterprise monitoring (historical + real-time)

Monitoring Best Practices

Test Quality Best Practices

Establish baselines:

• Healthy: Test failure rate < 5%
• Warning: Test failure rate 5-10%
• Critical: Test failure rate > 10%

Identify flaky tests:

• Failure rate between 10-90% (inconsistent results)
• Recommend investigation or test refactoring

Alert on patterns:

• New test with 100% failure rate (incorrect test logic)
• Previously stable test suddenly failing
• Test execution time 2x+ baseline

Model Performance Best Practices

Performance thresholds:

• Investigate: Models consistently > 5 minutes
• Critical: Runtime increase > 2x historical average
• Optimize: Models in top 20 slowest

Alert strategies:

• High priority: Models with status = 'error'
• Medium priority: Runtime increase > 50% from baseline
• Low priority: Slow model trending (track over time)

Alerting Best Practices

High Priority (Immediate Action):

• Test status = 'fail' or 'error'
• Model status = 'error'
• Critical model runtime > 2x baseline
• Production environment failures

Medium Priority (Investigation Within 24h):

• Test status = 'warn'
• Model skipped > 10% of runs
• Runtime increase > 50% from baseline
• Unusual invocation patterns

Low Priority (Track Trends):

• Slow model performance (not critical path)
• Test success rate slowly declining
• Incremental drift in execution duration
