-- Collector: ActivityCollector ("activity")
-- ===================================================================================================================
-- Hvad:        Åbne brugertransaktioner (alder, log) og brugersætninger, der har kørt længere end grænsen. Agentens
--              egne sessioner er udeladt.
-- Fil:         src/SQLInsight.Collectors/Concurrency/ActivityCollector.cs
-- Interval:    1 min som standard (SQLInsight:CollectorIntervals:activity)
-- 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)
--   GRANT VIEW SERVER SECURITY STATE TO [agent];       -- SQL Server 2022+
--
-- Bruges af:   SQLI-TRAN-001, SQLI-TRAN-002, SQLI-REQ-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.
