API request examples for creating Data Collection Rules (DCRs)

This article presents some examples of API requests and responses for creating Data Collection Rules (DCRs) and DCR Associations (DCRAs) for use with the Azure Monitor Agent (AMA).

The following examples are for DCRs using the AMA to collect Syslog and CEF messages.

These examples are of the API request and response for creating a DCR.

Example:

PUT https://management.chinacloudapi.cn/subscriptions/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee/resourceGroups/ContosoRG/providers/Microsoft.Insights/dataCollectionRules/Contoso-DCR-01?api-version=2022-06-01

The following is an example of a DCR creation request. For each data source stream—you can have several in one DCR—add a new subsection under "syslog" in the "dataSources" section and set the value of the "streams" field according to the source of the messages you want to ingest:

See the example of multiple streams sections in the following code sample:

{
  "location": "chinanorth3",
  "kind": "Linux",
  "properties": {
    "dataSources": {
      "syslog": [
        {
          "name": "localsSyslog",
          "streams": [
            "Microsoft-Syslog"
          ],
          "facilityNames": [
            "auth",
            "local0",
            "local1",
            "local2",
            "local3",
            "syslog"
          ],
          "logLevels": [
            "Critical",
            "Alert",
            "Emergency"
          ]
        },
        {
          "name": "authprivSyslog",
          "streams": [
            "Microsoft-Syslog"
          ],
          "facilityNames": [
            "authpriv"
          ],
          "logLevels": [
            "Error",
            "Alert",
            "Critical",
            "Emergency"
          ]
        }
      ]
    },
    "destinations": {
      "logAnalytics": [
        {
          "workspaceResourceId": "/subscriptions/aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee/resourceGroups/ContosoRG/providers/Microsoft.OperationalInsights/workspaces/Contoso",
          "workspaceId": "11111111-2222-3333-4444-555555555555",
          "name": "DataCollectionEvent"
        }
      ]
    },
    "dataFlows": [
      {
        "streams": [
          "Microsoft-Syslog"
        ],
        "destinations": [
          "DataCollectionEvent"
        ]
      }
    ]
  }
}

Here's the response you should receive according to the sample request above:

  {
    "properties": {
      "immutableId": "dcr-0123456789abcdef0123456789abcdef",
      "dataSources": {

          {

            ],
            "facilityNames": [
              "auth",
              "local0",
              "local1",
              "local2",
              "local3",
              "syslog"
            ],
            "logLevels": [
              "Critical",
