New Features

New in Q2'13

• New profiler analysis- the smart new profiler quickly shows you the root causes of memory and performance issues. If your app has a memory leak, you can use the WPF leaks or the disposed objects views to analyse different technologies. If your app is experiencing a performance issue, the new Bottlenecks view pinpoints which methods reduce performance and help optimise your app.
• Enhanced user experience- the updated, clean UI makes navigation and work-flow intuitive and fast. The improved In-Session experience will guide your profiling every step of the way.

New in Q1'13

• Enhanced Visual Studio experience- now runs as a Visual Studio extension in a separate process for improving Visual Studio performance. An updated UI helps you start to profile your apps in no time.
• Instance-level comparison of memory snapshots- instance-level snapshot comparisons allow you to track the identity of objects between snapshots and present instance-level comparison.
• Largest memory retainers improvements- now shows the name and the parent class of the field, and for arrays of reference types JustTrace shows the array index where an instance is stored.

New in Q3'12

• New UI and user experience- a simplified workflow and a more intuitive process make JustTrace easier to use
• Start page- the start page is now organised into backstage tabs making it clearer and to the point
• The ribbon- when you start a profiling session you will see a ribbon which gives you all options from the profiled application control toolbar and snapshot options toolbar
• The timeline- shows in real time the performance/memory usage of the profiled app, and by using the Timeline control, you will be able to see performance data for certain periods of time or make memory snapshots
• Class layout information- collects the class layout information and it helps show you the names of the members holding references to the live objects
• Visual Studio 2012 compliance- introduces support for Visual Studio 2012 color themes (dark and light)
• Windows 8 .NET apps support- introduces support for profiling .NET Windows 8 applications (formerly known as Metro apps)
• Performance and memory footprint improvements- improvements in how fast JustTrace will profile and load the snapshot data for your app.

Features

Profiling of multiple application types

With JustTrace, you can generate memory and performance profiles of a number of different application types, including:

• Local Application – executable file on the local computer
• Running Application - application that is already running
• Silverlight Application
• Local ASP.NET web site - web site folder on the local computer.

Three profilers for every profiling requirement

Memory and performance analysis is not a 'one size fits all' process, which is why there are three distinct profilers to satisfy a range of different profiling requirements and objectives.

• The Sampling Profiler dumps the call stacks for all threads executed by the profiled application at regular intervals using operating system interrupts. This approach has negligible performance hit on the profile, allowing it to run at near-full speed, but might trigger results with sub-optimal accuracy. If blazing speed and uncompromised performance rank high on your criteria list, the JustTrace Sampling Profiler is for you.
• The Tracing Profiler collects CLR events when entering and leaving methods. Tracing profilers boast more accurate results than sampling profilers but the trade-off is lower speed of execution.
• The Memory Profiler collects CLR memory usage data during execution of the program and helps you optimise memory usage. This profiler allows you to instantly and effortlessly identify memory leaks by comparing snapshots that include data about .NET instance allocations and eliminate any bottlenecks to optimal memory utilisation.

Memory and performance visualisation tools

JustTrace boasts a number of distinct snapshot views enabling a bird-eye view of critical memory and performance metrics. During the profiling session, the performance data is collected on-the-fly and can be examined in the Live Data view or in a snapshot. Once the snapshot is taken, you can analyse the data, identify bottlenecks and devise an action plan for removing obstacles to optimal performance and memory usage. The information about the profiled application is presented in JustTrace via several different views to enable easier visualisation, depending on the profiler type:

• Call Tree - This view is used in the Sampling and Tracing profilers and represents all function calls by a thread. Each snapshot contains the call tree structure of the application being profiled. The top-level node represents a thread and nodes represent a method called by the thread and its execution path.
• Method List - This view is used in the Sampling and Tracing profilers and represents all functions called in the profiled application during the profiling process.
• Hot Spots - Available in all three profilers. Within the Sampling and Tracing Profilers, the Hot Spots view represents a callback tree for each method. Within the Memory Profiler, the Hot Spots view tracks the object instances created during the profiling process grouped by type.
• Type List - This view is exclusive to the Memory Profiler and represents a list containing all object types and their size created during the profiling process.
• Loaded Assemblies - This view is used in the Sampling and Tracing profilers and represents a list containing all assemblies loaded during the profiling process.
• Incoming References - The Incoming References view is used in the Memory Profiler and represents the classes and methods that have referred the present object.
• Outgoing References - The Outgoing References view is exclusive to the Memory Profiler and represents the classes and methods the object is referring to. If the object has created any objects during the profiling process, those objects are shown as child nodes.

Attach profilers to an already running process

It’s not uncommon for a performance issue or memory leak to become apparent only after the application has been running for some time. The ‘Attach to a Running Process’ functionality of Telerik JustTrace enables you to quickly attach to the process rather than starting it again from scratch and trying to reproduce the current state. Currently, this functionality is only available within the Sampling Profiler but the product plans include its expansion to the Tracing and Memory Profilers as well.

Live data view

The Sampling and Tracing Profilers of JustTrace come equipped with a 'Live Data' view, which is updated on-the-fly with the latest data collected from the profiled application. This view enables you to better determine the perfect timing for taking a snapshot.

Seamless integration with Visual Studio

JustTrace offers seamless integration with Visual Studio and can also be used as a stand-alone tool. You just press F5 (to debugging) or CTRL + F5 (to start without debugging) and you are provided with a simple window to choose which profiler you want to use. And that's it, no additional settings are needed. The information you require is provided in a native Visual Studio tool window.

Profile Windows Servers

JustTrace is able to profile Windows Services on Windows 2003, Windows XP, Windows Vista and later versions. The ‘Profiling Windows Services’ capability entails a new, easy to use dialog, which enables you to see the list of all services and their status. And just above it you can find three buttons that allow you to start, stop and restart the selected service. In the same dialog, you can attach the Sampling profiler to a running .NET4 windows service.

Profile IIS and IIS Express services

This feature allows you to profile web sites, web services or other .NET components deployed on a local IIS server. Currently JustTrace is able to profile web sites on local IIS in Windows Vista and later versions only. The supported browsers are Internet Explorer and Google Chrome. Future plans include support for Windows XP and Windows 2003, and working with browsers as Mozilla Firefox and Opera.

Auto Update

As with all other Telerik products, JustTrace is subject to an aggressive release schedule with 3 major releases per year and a large number of (sometimes weekly) builds in the meantime. The ‘Auto Update’ functionality will enable you to use the latest and greatest version at all times.

Compare Snapshots

This is a really cool new feature! It allows you to compare two snapshots, identify the better scenario, and revert to a previous state if a certain optimisation technique has not produced the expected results. Simply drag-and-drop one snapshot tab over another to effortlessly find out how the app’s performance has changed between two performance snapshots. There is a simplified color scheme for easy hot spot identification, too.
