Azure 監視器中的數據收集規則範例
本文包含不同案例的範例數據收集規則（DCR）。 如需這些 DCR 中每個屬性的描述，請參閱 數據收集規則結構。
Azure 監視器代理程式 - 事件和效能數據
下列範例 數據收集規則 適用於具有 Azure 監視器代理程式的 虛擬機，並具有下列詳細數據：
- 效能資料
- 每隔 15 秒收集一次特定的處理器、記憶體、邏輯磁碟和實體磁碟計數器，並每分鐘上傳一次。
- 每隔 30 秒收集一次特定處理序計數器，並每隔 5 分鐘上傳一次。
- Windows 事件
- 收集 Windows 安全性事件，並每分鐘上傳一次。
- 收集 Windows 應用程式和系統事件，並每隔 5 分鐘上傳一次。
- syslog
- 從 Cron 設備收集偵錯、重大和緊急事件。
- 從 syslog 設備收集警示、重大和緊急事件。
- Destinations
- 將所有資料傳送至名為 centralWorkspace 的 Log Analytics 工作區。
注意
如需用來在資料收集規則中指定事件收集的 XPath 說明，請參閱使用自訂 XPath 查詢來限制資料收集。

Azure 監視器代理程式 - 文字記錄
下列範例數據收集規則是用來使用 Azure 監視器代理程式收集文字記錄。 請注意，自定義文字記錄的數據流名稱應該以 “Custom-” 前置詞開頭。

"outputStream": "Custom-MyTable_CL"
}
]
}
}
工作區轉換 DCR

{
"workspaceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/my-resource-group/providers/Microsoft.OperationalInsights/workspaces/my-workspace",
"name": "clv2ws1"
}
]
},
"dataFlows": [
{
"streams": [
"Microsoft-Table-LAQueryLogs"
],
"destinations": [
"clv2ws1"
],
"transformKql": "source |where QueryText !contains 'LAQueryLogs' | extend Context = parse_json(RequestContext) | extend Resources_CF = tostring(Context['workspaces']) |extend RequestContext = ''"
}
