Data Monitoring / Power BI Refresh & Data Reliability
Power BI: Gateway availability versus source access
The gateway is online but a semantic model cannot read its database. Check the failed refresh step, gateway mapping and source connection under the configured service identity.
Environment and inputs: Power BI Desktop and Power BI service; gateway, connector, capacity and license capabilities depend on the deployed configuration.
Failure scenario
The gateway is online but a semantic model cannot read its database. Confirm the cause before choosing a fix.
Evidence to collect
Check the failed refresh step, gateway mapping and source connection under the configured service identity. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Correct the specific connection or permission and rerun a small refresh before the full model. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for gateway availability versus source access using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
