Monitor Databricks jobs, clusters, SQL warehouses, and costs using system tables in the system catalog. System tables provide queryable observability data: system.lakeflow (job runs), system.billing (costs), system.query (SQL history), system.access (audit logs), and system.compute (cluster metrics). Data updates throughout the day, not real-time.
Prerequisites
Databricks Premium or Enterprise with Unity Catalog enabled
Access to system.billing, system.lakeflow, system.query, and system.access schemas
-- DBU consumption by cluster (last 7 days)SELECT usage_metadata.cluster_id,
COALESCE(usage_metadata.cluster_name, 'unnamed') AS cluster_name,
sku_name,
SUM(usage_quantity) AS total_dbus,
ROUND(SUM(usage_quantity * p.pricing.default), 2) AS cost_usd
FROM system.billing.usage u
LEFTJOIN system.billing.list_prices p ON u.sku_name = p.sku_name
WHERE u.usage_date >=current_date() -INTERVAL7 DAYS
GROUPBY usage_metadata.cluster_id, cluster_name, u.sku_name
ORDERBY cost_usd DESC
LIMIT 20;
Step 3: SQL Warehouse Performance
-- Slow queries (>30s) on SQL warehousesSELECT warehouse_id, statement_id, executed_by,
ROUND(total_duration_ms /1000, 1) AS duration_sec,
rows_produced,
ROUND(bytes_scanned /1048576, 1) AS scanned_mb,
LEFT(statement_text, 200) AS query_preview
FROM system.query.history
WHERE total_duration_ms >30000AND start_time >current_timestamp() -INTERVAL24 HOURS
ORDERBY total_duration_ms DESC
LIMIT 50;
-- Warehouse queue times (right-sizing indicator)SELECT warehouse_id, warehouse_name,
COUNT(*) AS query_count,
ROUND(AVG(total_duration_ms) /1000, 1) AS avg_sec,
ROUND(MAX(queue_duration_ms) /1000, 1) AS max_queue_sec
FROM system.query.history
WHERE start_time >current_timestamp() -INTERVAL7 DAYS
GROUPBY warehouse_id, warehouse_name;
Step 4: Cost-per-Job Analysis
SELECT j.name AS job_name,
COUNT(DISTINCT r.run_id) AS run_count,
ROUND(AVG(TIMESTAMPDIFF(MINUTE, r.start_time, r.end_time)), 1) AS avg_min,
ROUND(SUM(b.usage_quantity), 1) AS total_dbus,
ROUND(SUM(b.usage_quantity * p.pricing.default), 2) AS total_cost_usd
FROM system.lakeflow.job_run_timeline r
JOIN system.lakeflow.jobs j ON r.job_id = j.job_id
LEFTJOIN system.billing.usage b
ON r.run_id = b.usage_metadata.job_run_id
LEFTJOIN system.billing.list_prices p ON b.sku_name = p.sku_name
WHERE r.start_time >current_timestamp() -INTERVAL7 DAYS
GROUPBY j.name
ORDERBY total_cost_usd DESC
LIMIT 15;
Step 5: SQL Alerts for Automated Notifications
-- Create as SQL Alert: trigger when failure_count > 3-- Schedule: every 15 minutes-- Notification destination: Slack/emailSELECTCOUNT(*) AS failure_count
FROM system.lakeflow.job_run_timeline
WHERE result_state ='FAILED'AND start_time >current_timestamp() -INTERVAL1HOUR;
from databricks.sdk import WorkspaceClient
w = WorkspaceClient()
# Create SQL alert programmatically
alert = w.alerts.create(
name="Hourly Job Failure Alert",
query_id="<saved-query-id>",
options={"column": "failure_count", "op": ">", "value": "3"},
rearm=900, # re-alert after 15 min if still triggered
)
Step 6: Export Metrics to External Systems
from databricks.sdk import WorkspaceClient
w = WorkspaceClient()
# Export cluster state metrics for Prometheus/Datadogfor cluster in w.clusters.list():
if cluster.state.value == "RUNNING":
print(f"databricks_cluster_workers{{name=\"{cluster.cluster_name}\"}} "f"{cluster.num_workers}")
print(f"databricks_cluster_running{{name=\"{cluster.cluster_name}\"}} 1")
# Export job success rate for Grafana
runs = list(w.jobs.list_runs(limit=100, completed_only=True))
success = sum(1for r in runs if r.state.result_state and r.state.result_state.value == "SUCCESS")
print(f"databricks_job_success_rate {success / len(runs):.2f}")
Step 7: Audit Log Monitoring
-- Security: who accessed what in the last 7 daysSELECT event_time, user_identity.email, action_name,
request_params, response.status_code
FROM system.access.audit
WHERE service_name IN ('unityCatalog', 'jobs', 'clusters')
AND event_date >=current_date() -7AND action_name NOTIN ('getStatus', 'list') -- exclude noisy readsORDERBY event_time DESC
LIMIT 100;
Output
Job health dashboard (success rate, duration, failures)
Automated SQL alerts with Slack/email notifications
External metric export for Prometheus/Grafana
Error Handling
Issue
Cause
Solution
System tables empty
Unity Catalog not enabled
Enable in Account Console > Settings
TABLE_OR_VIEW_NOT_FOUND
Schema not accessible
Request admin to grant SELECT ON system.billing
Billing data delayed
System table refresh lag (up to 24h)
Use for trends and alerts, not real-time
Query history missing
Serverless queries not tracked
Use classic SQL warehouse or check retention
Examples
Daily Standup Dashboard
-- Single query for daily pipeline healthSELECT'Last 24h'ASperiod,
COUNT(*) AS total_runs,
COUNT(CASEWHEN result_state ='SUCCESS'THEN1END) AS ok,
COUNT(CASEWHEN result_state ='FAILED'THEN1END) AS failed,
ROUND(AVG(TIMESTAMPDIFF(MINUTE, start_time, end_time)), 1) AS avg_min
FROM system.lakeflow.job_run_timeline
WHERE start_time >current_timestamp() -INTERVAL24 HOURS;
