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.

-- Collector: PerformanceCounterCollector ("performance-counters")
|
|
-- ===================================================================================================================
|
|
-- Hvad: Udvalgte performance counters: memory grants, page life expectancy, forbindelser, blokerede processer,
|
|
-- batch requests og kompileringer.
|
|
-- Fil: src/SQLInsight.Collectors/Performance/PerformanceCounterCollector.cs
|
|
-- Interval: 5 min som standard (SQLInsight:CollectorIntervals:performance-counters)
|
|
-- Versioner: Alle (SQL Server 2000 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)
|
|
-- GRANT VIEW SERVER SECURITY STATE TO [agent]; -- SQL Server 2022+
|
|
-- SQL Server 2000 har ikke VIEW SERVER STATE; se docs/legacy-versions.md (fx kræver DBCC SQLPERF(WAITSTATS) forhøjede rettigheder).
|
|
--
|
|
-- Bruges af: SQLI-MEM-001, SQLI-ANOM-001
|
|
-- 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.
