Rider memory profiler

With JetBrains Rider, you can explore the managed heap while debugging and look into the memory space that is used by your application, rider memory profiler. When the debugger hits a breakpointyou can open the memory view in a separate tab of the Debug window. After clicking the grid, JetBrains Rider shows us the total number of objects in the rider memory profiler grouped by their full type name, the number of objects and bytes consumed.

The goal of performance profiling is to find the cause of performance issues in an application. This includes, for example, a straightforward "what is the slowest method? JetBrains Rider integrates with the dotTrace profiler to provide performance profiling of. NET applications. You can use the profiler via the dotTrace Profiler tool window.

Regardless of what application type you are going to profile, the workflow always looks the same:. Decide which profiling configuration you will use. Run the profiling session and get the data. In the run widget menu, choose Profile with , then choose a profiling configuration:. Once the profiling is started, Rider will open an Analysis editor document with the profiling controller inside. Reproduce the issue you are looking for or, if you just want to evaluate the memory usage, go through the desired usage scenarios in your application. Get Snapshot button to take one or more memory snapshots for example, before and after a particular activity in your application. If you want to analyze only memory allocation, you can take no snapshots at all. Get Snapshot by Condition button to set up getting snapshots on a specific condition. After you collect the data, you can finish the profiling session. Normally, you do it either by closing the profiled application or by detaching the profiler via the Detach button Kill forcibly terminates the profiled application and the session, so, use it only in emergency cases. Analyze the collected data. This includes memory allocation data and memory snapshots.

Attaching to running Mono processes is not possible. Specify configuration Name and other profiling options: Control profiling manually Enables you to control profiling manually via the profiler controls, rider memory profiler.

Use the Memory Allocation view to analyze allocations on a specific time interval: find out what objects were allocated on this interval and what functions allocated these objects. The view can show you allocation data even when profiling is still in progress: memory snapshots are not required. Default, Windows only dotMemory collects limited allocation data: For each function that allocates objects you can view only approximate object sizes. The information about object count is not available. The data is not detailed because it is based on ETW events: the allocation event is triggered each time the size of the allocated memory exceeds KB in total.

Having a profiling tool integrated into your IDE is an asset no developer can discount the value of. The undeniable convenience of being able to screen your app for performance issues on the fly is why the dotTrace profiler comes integrated into Rider. Disclaimer: dotMemory Profiler is currently only available on Windows in Rider Linux and MacOS versions of the plugin are to follow in the next releases. Download Rider Whenever you encounter performance issues, it helps to keep in mind that one set of problems can actually stem from different causes. Slow performance can either be a symptom of calling expensive methods too often or over-allocation and garbage collection. Our general recommendation for fine-tuning your app is to start with dotTrace and then follow it up with dotMemory to reduce allocations, reduce garbage collection pressure, and investigate any other memory issues slowing your application down. The

View Tool Windows dotMemory Profiler. This window allows you to profile and analyze memory issues in. NET applications. The dotMemory Profiler is a multi-tab window consisting of:. The Running Processes tab used to attach the profiler to a running process. The Recent Workspaces tab used to open collected workspaces.

Application type will include all calls made during the profiling session as the application is started by the Application. Currently, you are able to profile the following run configuration types:. To switch the grouping type, use the Type , Namespace , and Assembly buttons at the top of the table. Objects The number of objects of the same type. The data is not detailed because it is based on ETW events: the allocation event is triggered each time the size of the allocated memory exceeds KB in total. For example, it's obvious that a subsystem for the System. If you select a run configuration of some other type, this will disable the profiling controls on the toolbar. Last modified: 18 March NET Framework 4. The Call Tree view shows the call tree for the selected time interval. Installation and licensing dotTrace and dotMemory are provided as a single bundled plugin for JetBrains Rider, which is added and enabled automatically during the IDE installation. The Detach operation is available only in case you attach the profiler to an already running app.
