Answer 1

In the resources array of the resource for which you want to enable Diagnostic Logs, add a resource of type [resource namespace]/providers/diagnosticSettings.
Example :
"resources": [
{
"type": "providers/diagnosticSettings",
"name": "[concat('Microsoft.Insights/', parameters('settingName'))]",
"dependsOn": [
"[/*resource Id for which Diagnostic Logs will be enabled>*/]"
],
"apiVersion": "2017-05-01-preview",
"properties": {
"name": "[parameters('settingName')]",
"storageAccountId": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]",
"eventHubAuthorizationRuleId": "[parameters('eventHubAuthorizationRuleId')]",
"eventHubName": "[parameters('eventHubName')]",
"workspaceId": "[parameters('workspaceId')]",
"logs": [
{
"category": "/* log category name */",
"enabled": true,
"retentionPolicy": {
"days": 0,
"enabled": false
}
}
],
"metrics": [
{
"category": "AllMetrics",
"enabled": true,
"retentionPolicy": {
"enabled": false,
"days": 0
}
}
]
}
}
]

Update : To set the value of Web Server logging use the below example
"properties": {
"applicationLogs": {
"Storage": {
"level": "Verbose"
}
},
"httpLogs": {
"fileSystem": {
}
}
}
If you want Storage or fileSystem use any one of above

I got this working by setting the httpLogs and httpLoggingEnabled properties.
This is the config resource nested within a site resource:
"resources": [
{
"apiVersion": "2018-02-01",
"type": "config",
"name": "logs",
"dependsOn": [
"[concat('Microsoft.Web/sites/', parameters('name'))]"
],
"properties": {
"applicationLogs": {
"azureBlobStorage": {
"level": "information",
"retentionInDays": 15
}
},
"httpLogs": {
"fileSystem": {
"retentioninMb": 35,
"retentioninDays": 15,
"enabled": true
}
},
"requestTracingEnabled": true,
"requestTracingExpirationTime": "9999-12-31T23:59:00Z",
"remoteDebuggingEnabled": false,
"httpLoggingEnabled": true,
"logsDirectorySizeLimit": 34,
"detailedErrorLoggingEnabled": true
}
}
]
