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.

-- SQLI-OPS-001: Backup eller restore kører markant længere end normalt
|
|
-- ===================================================================================================================
|
|
-- Regel-id: SQLI-OPS-001
|
|
-- Titel: Backup eller restore kører markant længere end normalt
|
|
-- Alvor: Medium
|
|
-- Versioner: SQL Server 2005 og nyere.
|
|
--
|
|
-- Hvad tjekkes, og hvorfor:
|
|
-- Om en backup eller restore kører markant længere end samme kommando på samme database plejer.
|
|
--
|
|
-- Vurdering (sker i C# ud fra de indsamlede data, ikke i SQL'en, medmindre andet er nævnt):
|
|
-- Hvert minut læses de kørende operationer med percent_complete > 0. Afsluttede operationer på mindst 1 minut
|
|
-- huskes (de seneste 10 pr. kommando og database). Fund for kørende BACKUP/RESTORE, når der er mindst 3 tidligere
|
|
-- kørsler, og den har kørt mere end 2 x medianen og mindst 5 minutter længere end medianen.
|
|
--
|
|
-- Grænseværdier (konfigurationsnøgle i agentens appsettings.json og standardværdi):
|
|
-- Faktor 2 (SlowBackupRule.Factor); mindst 5 minutter over medianen; mindst 3 tidligere kørsler (fast i koden).
|
|
--
|
|
-- 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+
|
|
--
|
|
-- Data kommer fra (collector, fil : medlemmer, interval):
|
|
-- LongOperationCollector
|
|
-- Fil: src/SQLInsight.Collectors/Instance/LongOperationCollector.cs
|
|
-- Medlemmer: LongOperationCollector.Sql
|
|
-- Interval: 1 min som standard (SQLInsight:CollectorIntervals:long-operations)
|
|
-- Delt script: SQL Scripts/_collectors/LongOperationCollector.sql
|
|
-- Regelkode: src/SQLInsight.Rules/Performance/OperationRules.cs : SlowBackupRule.Evaluate
|
|
--
|
|
-- Read-only: Ja: kun SELECT samt SET-sessionsindstillinger. Intet ændrer data, indstillinger eller objekter.
|
|
-- Kørsel: Kør i SSMS som agentens login (eller et login med samme rettigheder). Hver variant er sin egen batch
|
|
-- (GO); en variant for en anden SQL Server-version end din kan fejle - det er forventet.
|
|
-- Per-database-forespørgsler er vist for databasen msdb, som findes overalt: ret navnet til den
|
|
-- database, du vil se.
