Contoh aturan pengumpulan data (DCR) di Azure Monitor
Artikel ini menyertakan contoh aturan pengumpulan data (DCR) untuk skenario yang berbeda. Untuk deskripsi setiap properti dalam DCR ini, lihat Struktur aturan pengumpulan data.
Agen Azure Monitor - peristiwa dan data performa
Contoh aturan pengumpulan data di bawah ini adalah untuk komputer virtual dengan agen Azure Monitor dan memiliki detail berikut:
- Data performa
- Mengumpulkan penghitung Prosesor, Memori, Disk Logis, dan Disk Fisik tertentu setiap 15 detik dan mengunggah setiap menit.
- Mengumpulkan penghitung Proses tertentu setiap 30 detik dan mengunggah setiap 5 menit.
- Peristiwa Windows
- Mengumpulkan peristiwa keamanan Windows dan mengunggah setiap menit.
- Mengumpulkan aplikasi Windows dan peristiwa sistem serta mengunggah setiap 5 menit.
- Syslog
- Mengumpulkan Debug, Kritis, dan Peristiwa darurat dari fasilitas cron.
- Mengumpulkan Peringatan, Kritis, dan Peristiwa darurat dari fasilitas syslog.
- Tujuan
- Mengirim semua data ke ruang kerja Log Analytics bernama centralWorkspace.
Catatan
Untuk penjelasan tentang XPath yang digunakan untuk menentukan pengumpulan peristiwa dalam aturan pengumpulan data, lihat Membatasi pengumpulan data dengan kueri XPath kustom.

API penyerapan log
Contoh aturan pengumpulan data di bawah ini digunakan dengan API penyerapan Log. Aturan tersebut memiliki rincian sebagai berikut:
- Mengirim data ke tabel yang disebut MyTable_CL di ruang kerja yang disebut ruang kerja saya.
- Menerapkan transformasi ke data yang masuk.

"outputStream": "Custom-MyTable_CL"
}
]
}
}
DCR transformasi ruang kerja
Contoh aturan pengumpulan data di bawah ini digunakan sebagai DCR transformasi ruang kerja untuk mengubah semua data yang dikirim ke tabel yang disebut LAQueryLogs.
{
"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 = ''"
