A DBA should be able to review every statement SQLInsight sends to a monitored server before granting it access. "SQL Scripts/<rule-id>.sql" holds, per rule (82 built-in, 16 community), a Danish header (what and why, how C# judges the data, thresholds with config keys, severity, exact GRANTs, versions, collector file and member) and the collector's SQL verbatim, every version variant as its own batch. "_collectors/<Collector>.sql" holds each collector's queries once. The only statement that is not strictly read-only is documented in the scripts: the deadlock collector's session temp table (#system_health). Inline SQL in the collectors moved to internal constants and Build*Sql methods (no text changed), so SqlScriptTests can check that the scripts still contain the SQL the code sends, that every rule has a script, that every collector query is registered, and that nothing writes.

-- Hvad: Active session sampling: hvad ventende brugerrequests venter på. Bruges af tidsvindue-analysen i
|
|
-- web-UI'et, ikke af nogen regel.
|
|
-- Fil: src/SQLInsight.Collectors/Performance/WaitSamplingCollector.cs

|
-- Interval: 15 sek som standard (SQLInsight:CollectorIntervals:wait-sampling)

-- Versioner: SQL Server 2005 og nyere

-- Rettigheder til agentens login (se db/permissions/grant-least-privilege.sql; [agent] = agentens login):
|
|
-- GRANT VIEW SERVER STATE TO [agent]; -- SQL Server 2005-2019
|
|
-- GRANT VIEW SERVER PERFORMANCE STATE TO [agent]; -- SQL Server 2022+ (erstatter VIEW SERVER STATE)

|
|
-- Bruges af: Ingen regel (kun web-UI'ets analyse).
|
|
-- Read-only: Ja: kun SELECT samt SET-sessionsindstillinger. Intet ændrer data, indstillinger eller objekter.
|
|
-- Kørsel: Kør i SSMS som agentens login. Hver variant er sin egen batch (GO); en variant for en anden SQL Server-version
|
|
-- end din kan fejle - det er forventet. Agenten kører altid med sessionsindstillingerne i _collectors/InstanceProbe.sql.
