One reviewable file per rule id with a Danish header: what and why, thresholds with config keys and defaults, severity, required rights (never local administrator), supported versions, collector file and member, and the evaluation in plain Danish. The Windows rules use no SQL: their exact CIM/WQL queries, event log XPath and a read-only PowerShell snippet to verify them are in a comment block. SQLI-SYN-001/002 carry the exact SQL a SQL check runs (session settings, transaction that is always rolled back, SELECT 1). A test checks every server and check rule has its file.

SQLI-WIN-004 – Den reserverede hukommelse (commit) er tæt på grænsen
|
||
=====================================================================
|
||
|
||
Hvad og hvorfor
|
||
Commit charge er den hukommelse, programmerne har reserveret (RAM plus sidefil). Når grænsen nås, kan Windows ikke
|
||
give mere hukommelse ud, og programmer og tjenester fejler, selv om der måske er ledig RAM.
|
||
|
||
Tærskler (agentens appsettings.json)
|
||
SQLInsight:Servers:Memory:CommitPercent standard 90 (CommittedBytes / CommitLimit, gennemsnit over 5 minutter)
|
||
|
||
Alvor
|
||
Middel; Høj ved 97 % eller derover.
|
||
|
||
Rettigheder på den overvågede server (db/permissions/grant-windows-server.ps1, aldrig lokal administrator)
|
||
Performance Monitor Users + WMI Enable Account/Remote Enable på root\cimv2
|
||
WS-Man: Remote Management Users · DCOM: Distributed COM Users
|
||
|
||
Understøttede versioner
|
||
Windows Server 2008 R2 og nyere.
|
||
|
||
Collector
|
||
src/SQLInsight.Servers/CimWindowsServerSource.cs – Session.GetPerformanceAsync (CimQueries.MemoryQuery), hvert minut
|
||
fra src/SQLInsight.Agent/Servers/ServerMonitor.cs – CollectPerformanceAsync.
|
||
Regel
|
||
src/SQLInsight.Rules/Servers/WindowsServerRules.cs – ServerCommitRule
|
||
|
||
Evaluering
|
||
100 × CommittedBytes / CommitLimit pr. minut; gennemsnittet over 5 minutter (mindst 80 % dækket) mod grænsen.
|
||
|
||
Reglen bruger ikke SQL. Forespørgslerne mod Windows står herunder; filen indeholder kun kommentarer og ændrer intet.
|
||
|
||
CIM/WQL (namespace root\cimv2):
|
||
SELECT AvailableMBytes, PagesPersec, CommittedBytes, CommitLimit, Timestamp_PerfTime, Frequency_PerfTime FROM Win32_PerfRawData_PerfOS_Memory
|
||
|
||
Efterprøv med PowerShell (skrivebeskyttet; kør på agentens server som agentens konto):
|
||
$s = New-CimSession -ComputerName SERVER
|
||
$m = Get-CimInstance -CimSession $s -Query "SELECT CommittedBytes, CommitLimit FROM Win32_PerfRawData_PerfOS_Memory"
|
||
100 * $m.CommittedBytes / $m.CommitLimit
|
||
