You set up databricks ai observability by turning on Unity Catalog system tables and inference logs. These features record model inputs, outputs, and user queries across your workspace. Most teams start by giving engineers broad read roles on these log tables. When roles are too broad, anyone checking model logs can read private data in plain text.
How databricks ai observability works in your workspace
The platform uses Unity Catalog to manage data rules and model assets in one place. When a team serves a model, the workspace captures request and response payloads. The platform writes these records straight into managed delta tables inside your catalog. Data teams also turn on system tables to track warehouse queries and job runs. These tables store who ran a query, when it ran, and which tables it touched. Engineers then build dashboards on top of these tables to check model drift and latency. They also use these logs to track token usage and billing across different teams. To make this work, admins grant read permissions on the catalog and schema. Every tool or person with that role can query the stored log rows.
What native logging solves and what it misses
Native logging gives you a central record of model traffic and compute usage. It helps teams spot slow queries, broken pipelines, and rising token costs after they happen. Admins can also check past billing logs to see which group spent the most budget. Still, workspace roles only decide who can log in and read a table. They do not check or filter what individual queries do while they run. Once a user or app has a role, every query runs with full table rights. Also, inference tables write the raw prompt and response right to disk. If a customer sends a card number or email, that text lands in the table. Anyone querying the logs for debugging will pull those raw values into their notebook. Static catalog rules cannot rewrite matched fields in results on the fly without extra views. Teams often end up copying tables or building brittle custom views for every single group.
Closing the gap for live queries and model calls
Relying only on post-run tables leaves a gap during live data operations. When an engineer troubleshoots a broken model, they often run live queries against production tables. Standard workspace logs record that the query happened, sometimes minutes after the data leaves. They cannot stop a risky command or ask a manager for approval before it runs. They also cannot mask emails, phone numbers, or national IDs inside live query results. To fix this, teams need controls that inspect every statement in flight. Data masking should rewrite sensitive fields like card numbers in the output stream right away. Approval checks should pause high-risk commands until a peer signs off in chat. This keeps production data safe while letting engineers check model issues fast.

Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
Where does the workspace store model request logs?
The platform writes model inputs and outputs into inference tables inside Unity Catalog. You must turn on payload logging on the serving endpoint to start saving these rows.
Can system tables block a dangerous SQL query before it runs?
No, system tables only record history after a query finishes running on a warehouse. They help with past audits, but they do not stop live commands in flight.
How can we hide private data in model debug logs?
Static roles grant all-or-nothing read rights to the log table. To hide emails or card numbers during queries, you need runtime masking that rewrites matched fields.
