Migration 0018_windows_servers_synthetic_checks:
- insight.WindowsServers (SQL Server hosts kept in step by the agent, servers added
in SQLInsight Web), ServerPerformance (per minute, one row per sample),
ServerDiskSamples (forecast history), ServerEvents (grouped like ErrorLogEvents),
ServerSnapshots (latest per area).
- insight.SyntheticChecks (SQL login password sealed for the agent, as in 1.3) and
SyntheticCheckResults.
- insight.ServerFindings and ServerRuleStates, scoped to a server or a check.
- AgentRequests.TargetId and the kinds ServerTest and SyntheticCheckRun.
- SQLInsight Web gets INSERT and column UPDATE only; host, name and kind are fixed,
nothing the agent records can be written, no DELETE.
Findings are opened, updated and resolved like instance findings; a round where a
rule is not measurable keeps what was found open. Retention for samples, disk
history, events, check results and resolved findings (RunServerMaintenanceAsync).
