To enable remote debugging for a cloud service Open the shortcut menu for the Azure project, and then select Publish. Select the Staging environment and the Debug configuration. This is only a guideline. You can opt to run your test environments in a Production environment. However, you may adversely affect users if you enable remote debugging on the Production environment. You can choose the Release configuration, but the Debug configuration makes debugging easier. Choose the Debug configuration Follow the usual steps, but select the Enable Remote Debugger for all roles check box on the Advanced Settings tab. Debug Configuration To attach the debugger to a cloud service in Azure In Server Explorer, expand the node for your cloud service. Open the shortcut menu for the role or role instance to which you want to attach, and then select Attach Debugger. If you debug a role, the Visual Studio debugger attaches to each instance of that role. The debugger will break on a breakpoint for the first role instance that runs that line of code and meets any conditions of that breakpoint. If you debug an instance, the debugger attaches to only that instance and breaks on a breakpoint only when that specific instance runs that line of code and meets the breakpoint's conditions. Attach Debugger After the debugger attaches to an instance, debug as usual. The debugger automatically attaches to the appropriate host process for your role. Depending on what the role is, the debugger attaches to w3wp.exe, WaWorkerHost.exe, or WaIISHost.exe. To verify the process to which the debugger is attached, expand the instance node in Server Explorer. See Azure Role Architecture for more information about Azure processes. Select code type dialog box To identify the processes to which the debugger is attached, open the Processes dialog box by, on the menu bar, choosing Debug, Windows, Processes. (Keyboard: Ctrl+Alt+Z) To detach a specific process, open its shortcut menu, and then select Detach Process. Or, locate the instance node in Server Explorer, find the process, open its shortcut menu, and then select Detach Process.

Abhijeet, Yes it is possible to debug the cloud services remotely with the help of debugging tools. what is the azure SDK version you are using? You can read more about it here - http://msdn.microsoft.com/en-us/library/azure/ff683670.aspx About reading logs generated by diagnostics, you can either use visual studio server explorer, select azure node, select your cloud service and open the WADLogs table else there are some other nice tools available which can help you. e.g. http://www.cerebrata.com/products/azure-management-studio/introduction
