Azure 監視器中的範例資料收集規則 (DCR)
本文包含不同案例的範例資料收集規則 (DCR)。 如需這些 DCR 中每個屬性的描述，請參閱資料收集規則結構。
注意
如果您使用 ARM 範本或 REST API 來建立或修改 DCR，這些範例會提供 DCR 的來源 JSON。 建立之後，DCR 會有額外的屬性，如 Azure 監視器中資料收集規則的結構所述。
Azure 監視器代理程式 - 事件和效能資料
以下範例資料收集規則 (部分機器翻譯) 適用於具有 Azure 監視器代理程式 (部分機器翻譯) 的虛擬機器，並具有下列詳細資料：
- 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 (部分機器翻譯)。

Azure 監視器代理程式 - 文字記錄
下列範例資料收集規則用來使用 Azure 監視器代理程式收集文字記錄 (部分機器翻譯)。 請注意，自訂文字記錄的資料流名稱應該以 "Custom-" 前置詞開頭。
{
"location": "eastus",
"properties": {
"streamDeclarations": {
"Custom-MyLogFileFormat": {
"columns": [
{
"name": "TimeGenerated",
"type": "datetime"
},
{
"name": "RawData",
"type": "string"
}
]
}
},
"dataSources": {
"logFiles": [
{
"streams": [
"Custom-MyLogFileFormat"
],
"filePatterns": [
"C:\\JavaLogs\\*.log"
],
"format": "text",

"text": {
"recordStartTimestampFormat": "ISO 8601"
}
},
"name": "myLogFileFormat-Windows"
},
{
"streams": [
"Custom-MyLogFileFormat"
],
"filePatterns": [
"//var//*.log"
],
"format": "text",
"settings": {
"text": {
"recordStartTimestampFormat": "ISO 8601"
}
},
"name": "myLogFileFormat-Linux"
}
]
},
"destinations": {
"logAnalytics": [
{
"workspaceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/my-resource-group/providers/Microsoft.OperationalInsights/workspaces/my-workspace",
"name": "MyDestination"
}
]
},
"dataFlows": [
{
"streams": [
"Custom-MyLogFileFormat"
],
"destinations": [
"MyDestination"
],
"transformKql": "source",
"outputStream": "Custom-MyTable_CL"
}
]
}
}
事件中樞
下列範例資料收集規則可用來從事件中樞收集資料 (部分機器翻譯)。
{
"location": "eastus",
"properties": {
"streamDeclarations": {
"Custom-MyEventHubStream": {
"columns": [
{
"name": "TimeGenerated",
"type": "datetime"
},
{
"name": "RawData",
"type": "string"
},
{
"name": "Properties",
"type": "dynamic"
}
]
}
},
"dataSources": {
"dataImports": {
"eventHub": {
"consumerGroup": "<consumer-group>",
"stream": "Custom-MyEventHubStream",
"name": "myEventHubDataSource1"
}
}
},
"destinations": {
"logAnalytics": [
{
"workspaceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/my-resource-group/providers/Microsoft.OperationalInsights/workspaces/my-workspace",
"name": "MyDestination"
}
]
},
"dataFlows": [
{
"streams": [
"Custom-MyEventHubStream"
],
"destinations": [
"MyDestination"
],
"transformKql": "source",
"outputStream": "Custom-MyTable_CL"
}
]
}
}
記錄擷取 API
下列範例資料收集規則 (部分機器翻譯) 會與記錄擷取 API (部分機器翻譯) 搭配使用。 其中含有下列詳細資料：
- 將資料傳送至工作區 my-workspace 中名稱為 MyTable_CL 的資料表。
- 將轉換套用至傳入的資料。
注意
記錄內嵌 API 需要 logsIngestion 屬性，其中包含端點的 URL。 此屬性會在建立之後新增至 DCR。
{
"location": "eastus",
"kind": "Direct",
"properties": {
"streamDeclarations": {
"Custom-MyTable": {
"columns": [
{
"name": "Time",
"type": "datetime"
},
{
"name": "Computer",
"type": "string"
},
{
"name": "AdditionalContext",
"type": "string"
}
]
}
},
"destinations": {
"logAnalytics": [
{
"workspaceResourceId": "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/cefingestion/providers/microsoft.operationalinsights/workspaces/my-workspace",
"name": "LogAnalyticsDest"
}
]
},
"dataFlows": [
{
"streams": [
"Custom-MyTable"
],
"destinations": [
"LogAnalyticsDest"
],
"transformKql": "source | extend jsonContext = parse_json(AdditionalContext) | project TimeGenerated = Time, Computer, AdditionalContext = jsonContext, ExtendedColumn=tostring(jsonContext.CounterName)",
"outputStream": "Custom-MyTable_CL"
}
]
}
}
工作區轉換 DCR
下列範例資料收集規則 (部分機器翻譯) 會做為工作區轉換 DCR (部分機器翻譯)，以轉換傳送至稱為「LAQueryLogs」資料表的所有資料。
{
"location": "eastus",
"properties": {
"destinations": {
"logAnalytics": [
{
"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 = ''"
}
]
}
}
