dotMemory Features

dotMemory is a .NET memory profiler that can be launched right from Visual Studio or as a standalone tool.

Support for various .NET applications

dotMemory lets you profile applications based on .NET Framework (2.0 and higher), such as desktop applications, ASP.NET web applications, IIS, IIS Express, Windows services, Universal Windows Platform applications, arbitrary .NET processes, and more. Starting with dotMemory 2016.3, you can also profile .NET Core applications.

Run dotMemory from Visual Studio

Visual Studio integration

dotMemory integrates with Visual Studio so you can start a memory profiling session right from the IDE, whenever you need.

Later on, you can navigate from a type in a dotMemory object set to the type's declaration in Visual Studio.

Timeline view

Timeline view with real-time data collection

Monitor memory consumed by your application, get snapshots and drop them to compare in one click.

Multiple views on data

Examine objects in the heap from multiple views. Want to know how objects relate to each other? What objects do they reference and through what fields? Want to know which calls created these objects? No problem! dotMemory has a view for everything.

Sunburst diagram

Sunburst diagram

Understanding of how memory is retained in your application is essential in order to successfully optimize it. In this view, the hierarchy of dominators (objects that exclusively retain other objects in memory) is shown on a sunburst chart.

Just a quick look at the chart allows you to find out what objects are crucial for your application and evaluate the largest structures: the more memory a dominator retains, the larger the central angle.

To get the retention path of the particular dominator click on the corresponding arc. Double-click on a dominator will zoom in the chart allowing you to see the objects retained by this dominator in more details.

Get snapshots automatically

Automatic snapshots

Sometimes you may be interested in taking snapshots only when a certain condition is true. This is why dotMemory makes it possible to automate the process of getting snapshots. This is especially helpful when the memory consumption of your application is dramatically increased, or when taking a snapshot manually gets tricky. Simply set a particular condition and have snapshots collected automatically after the condition is satisfied.

Comparing memory snapshots

Comparing two snapshots is the main way to find objects that are causing a memory leak. Use the comparison view to find out how many objects were created between snapshots and how many objects were collected.

Easy and comprehensive UI

While memory profiling has the reputation of being for pros only, dotMemory's unique user interface lowers that entry barrier dramatically and makes memory profiling straightforward. You simply move from top to bottom, from a set of objects down to particular instances, until you identify the real cause of memory issues.

Analyzing memory traffic

Analyzing memory traffic

Excessive allocations and garbage collections may imply significant memory management overhead. Use the traffic view to understand what objects are created/collected most intensively in your application and what functions are causing this memory traffic.

Powerful automatic inspections

dotMemory automatically scans your snapshot for common types of memory issues, such as string duplicates, sparse arrays, leaking event handlers or WPF bindings. These inspections can be a great starting point in analyzing a snapshot if you don't know where to begin.

Remote profiling

Profile applications not only on your local computer but on any computer in your network or on the Internet. Remote profiling is especially helpful when you need to profile a web application on a production server.

Profiling API

Taking the right moment for getting a snapshot is very important for memory analysis. Use the dotMemory API calls to take snapshots at the exact places of your code.
