Monitor job costs & performance with system tables
This article provides examples of how to use system tables to monitor the cost and performance of jobs in your account.
These queries only calculate costs for jobs run on jobs compute. Jobs run on SQL warehouses and all-purpose compute are not billed as jobs and are thus excluded from cost attribution.
Note
These queries won’t return records from workspaces outside your current workspace’s cloud region. To monitor job costs from workspaces outside your current region, run these queries in a workspace deployed in that region.
Requirements
The
system.lakeflow
schema must be enabled by an account admin. See Enable system table schemas.To access these system tables, users must either:
Be both a metastore admin and an account admin, or
Have
USE
andSELECT
permissions on the system schemas. See Grant access to system tables.
Jobs monitoring dashboard
The following dashboard uses system tables to provide you with comprehensive monitoring of your Databricks jobs and operational health. It includes common use cases such as job performance tracking, failure monitoring, and resource utilization.
Import the dashboard
Download the dashboard JSON file from the Databricks GitHub Repository.
Import the dashboard into your workspace. For instructions on importing dashboards, see Import a dashboard file.
Cost observability queries
The following queries from the dashboard demonstrate job cost monitoring capabilities.

This query identifies the jobs with the highest spend from the last 30 days.
