Profiler markers reference

Profiler counters reference

Unity has built-in profiler countersPlaced in code with the ProfilerCounter API to track metrics, such as the number of enemies spawned in your game. More info See in Glossary which you can use to collect and display metrics in custom ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating, or in your game logic. More info See in Glossary modules. The following tables outline the available built-in profiler counters. This information is also available via the ProfilerRecorder API and in the Profiler module editor so you can add them to a custom Profiler module. The following tables contain a list of profiler counters available in Unity:

File access profiler counters

The available file access profiler counters and availability in release (non-development) players are as follows:

Unavailable File Bytes Written Total number of bytes of information Unity wrote to this file during the selected frames. Unavailable File Handles Open The total number of file handles held open at any time during this frame. This includes files that Unity opens and closes within the same frame. Unavailable File Reads Finished Number of file reads completed during this frame.

Memory profiler counters

The following table outlines the available memory profiler counters and availability in release (non-development) players.

Tip: You can use the Object.FindObjectsByType method to find objects of specific types, and then pass this information to Profiler.GetRuntimeMemorySizeLong to get their memory amount and then implement this information in release players. For example, to get the counters for Mesh Count or Mesh Memory, use Object.FindObjectsByType<Mesh>().length and then pass these entries to GetRunTimeMemorySizeLong. Only use Find and its related APIs in development code.

GetRunTimeMemorySizeLong has an impact on performance, and doesnât provide graphics memory amounts in release builds.
