使用 ARM 模板设置 Linux 诊断扩展

Question

您好，我正在尝试创建一个 ARM 模板，以使用 ARM 模板在我的 Linux VM 上设置 Azure Linux 诊断扩展来监视挂载点。

我指的是以下文档来实现相同的目的：

https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-template

但是，通过研究 Microsoft 提供的其他文档，我发现 Windows 和 Linux 诊断代理具有不同的监视参数。

Windows：https : //docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-windows

Linux：https : //docs.microsoft.com/en-us/azure/virtual-machines/extensions/diagnostics-linux

Windows 的 ARM JSON 是：

"resources": [
    {
        "name": "Microsoft.Insights.VMDiagnosticsSettings",
        "type": "extensions",
        "location": "[resourceGroup().location]",
        "apiVersion": "2015-06-15",
        "dependsOn": [
            "[concat('Microsoft.Compute/virtualMachines/', variables('vmName'))]"
        ],
        "tags": {
            "displayName": "AzureDiagnostics"
        },
        "properties": {
            "publisher": "Microsoft.Azure.Diagnostics",
            "type": "IaaSDiagnostics",
            "typeHandlerVersion": "1.5",
            "autoUpgradeMinorVersion": true,
            "settings": {
                "xmlCfg": "[base64(concat(variables('wadcfgxstart'), variables('wadmetricsresourceid'), variables('vmName'), variables('wadcfgxend')))]",
                "storageAccount": "[parameters('existingdiagnosticsStorageAccountName')]"
            },
            "protectedSettings": {
                "storageAccountName": "[parameters('existingdiagnosticsStorageAccountName')]",
                "storageAccountKey": "[listkeys(variables('accountid'), '2015-05-01-preview').key1]",
                "storageAccountEndPoint": "https://core.windows.net"
            }
        }
    }
]

有谁知道Linux Diagnostic Agent for Linux的“ settings”和“ protectedSettings”是什么？

Answer 1

我在这里回答我自己的问题。

与适用于 Windows 的 Azure 诊断代理进行比较时的不同之处在于：

1. type这是在properties. 这将对应于LinuxDiagnostic而不是IaaSDiagnostics。
2. typehandlerversion: 这基本上是 LAD 版本。最新的一个是3.0。

3. protectedSettings: 可以这样写：

   { "storageAccountName" : "the storage account to receive data", "storageAccountEndPoint": "the hostname suffix for the cloud for this account", "storageAccountSasToken": "SAS access token", "mdsdHttpProxy": "HTTP proxy settings", "sinksConfig": { ... } }

mdsdHttpProxy 和 sinksConfig 参数是可选的，只有在进行了相同设置时才需要配置。可以在此处找到更多信息（在受保护的设置部分）。

4. settings：这将采用以下形式：

   { "ladCfg": { ... }, "perfCfg": { ... }, "fileLogs": { ... }, "StorageAccount": "the storage account to receive data", "mdsdHttpProxy" : "" }

此处（在公共场合）已详细讨论了其中的每一个。

对我有用的 Linux 诊断扩展的示例如下：
