         "location": "[resourceGroup().location]",
          "dependsOn": [
            "[concat('Microsoft.Network/ApplicationGateways/', parameters('applicationGateways_name'))]"
          ],
          "properties":{
            "name":"DiagService",
            "workspaceId":"[variables('workspaceId')]",
            "logs":[

        "name":"Diag",
        "workspaceId":  "[concat('/subscriptions/', subscription().subscriptionId,  '/resourceGroups/', resourceGroup().name, '/providers/microsoft.operationalinsights/workspaces/', parameters('workspaceId'))]",


        "logs":[
           {
             "category": "ApplicationGatewayAccessLog",
             "enabled": true,
             "retentionPolicy": {
             "enabled": false,
             "days": 0
                                }
