- Core/Servers: what the agent collects from a Windows server (CPU and memory from raw counters, disks, services, events, scheduled tasks), roles and sources, host validation and the computer behind a SQL Server data source. - DiskForecaster: "fuld om ca. N dage" from a least-squares line over 14 days of SQLInsight's own samples, only since the volume last changed size, with sanity bounds (history, samples, R², max one year). - ServerEventAnalysis: noise filter, grouping and a 24-hour window for System and Application events, like the SQL Server error log in 1.2. - db/permissions/grant-windows-server.ps1: least-privilege rights for the agent's account (groups, WMI namespaces, SCM read), never local administrator; filled in by ServerGrantScript. - Core/SyntheticChecks: kinds, settings, validation (read-only SQL), results.
