Monitor MariaDB health, cost and reliability signals, and catch incidents and runaway spend early. No changes are made without the configured approval policy. Read-only operations do not modify the connected system; schedules, access scopes, API usage and data handling remain governed by Vortex IQ controls.

Turn any finding into an automated fix with a Vortex IQ workflow: **13,885 read and write operations across 229 connectors** are available as building blocks, with approval, verification and rollback on every change. ## Automate approved work Vortex IQ is integrated with **6 read** and **0 write** operations across informationschemaglobalstatus where like 'wsrep%'s, performanceschemaeventstatementsummarybydigests, performanceschemaprocesslists, show global status, show replica status, show variables on MariaDB. Combine them with anything from the **13,885 operations across 229 connectors** to automate the work in your own words. Changes follow the merchant's configured approval policy: the target, proposed change, affected records, risk, reversibility and verification plan are shown before execution. Read-only operations do not modify the connected system.
