cli-anything-unrealinsights
Use this CLI when you need agent-friendly access to Unreal Insights trace capture and exporter workflows on Windows.
Prerequisites
- Unreal Engine 5.5+ installed with
UnrealInsights.exe - Windows
- Optional explicit env vars:
- UNREALINSIGHTS_EXE - UNREAL_TRACE_SERVER_EXE - UNREALINSIGHTS_TRACE
Core Commands
Backend discovery
cli-anything-unrealinsights --json backend infoTo use a source-built engine's matching UnrealInsights.exe:
cli-anything-unrealinsights --json backend ensure-insights `
--engine-root 'D:\code\D5\d5render-ue5_3'This first looks for Engine\Binaries\Win64\UnrealInsights.exe under the specified engine root, then builds it with that engine's Build.bat if needed.
Trace session state
cli-anything-unrealinsights trace set D:\captures\session.utrace
cli-anything-unrealinsights --json trace infoCapture orchestration
cli-anything-unrealinsights --json capture run `
--project 'D:\Projects\MyGame\MyGame.uproject' `
--engine-root 'D:\Program Files\Epic Games\UE_5.5' `
--output-trace D:\captures\boot.utrace `
--channels "default,bookmark" `
--exec-cmd "Trace.Bookmark BootStart" `
--wait --timeout 300You can also keep using the explicit form:
cli-anything-unrealinsights --json capture run `
'D:\Program Files\Epic Games\UE_5.5\Engine\Binaries\Win64\UnrealEditor.exe' `
--target-arg 'D:\Projects\MyGame\MyGame.uproject'Continuous capture session control
cli-anything-unrealinsights --json capture start `
--project 'D:\Projects\MyGame\MyGame.uproject' `
--engine-root 'D:\Program Files\Epic Games\UE_5.5' `
--output-trace D:\captures\live_session.utrace
cli-anything-unrealinsights --json capture status
cli-anything-unrealinsights --json capture snapshot D:\captures\live_snapshot.utrace
cli-anything-unrealinsights --json capture stopThis is the preferred flow when an agent needs to start profiling now and stop or snapshot later in a follow-up turn.
If a tracked capture session is still running, capture start now requires --replace so the previous process is stopped before a new one is launched.
Offline exporters
cli-anything-unrealinsights --json -t D:\captures\session.utrace export threads D:\out\threads.csv
cli-anything-unrealinsights --json -t D:\captures\session.utrace export timer-stats D:\out\stats.csv --region "EXPORT_CAPTURE"
cli-anything-unrealinsights --json -t D:\captures\session.utrace export counter-values D:\out\counter_values.csv --counter "*"Batch response files
cli-anything-unrealinsights --json -t D:\captures\session.utrace batch run-rsp D:\out\exports.rspJSON Output Guidance
- Prefer
--jsonfor agent workflows. - Export commands return:
- trace_path - exec_command - output_files - log_path - exit_code - warnings - errors - succeeded
- Capture returns:
- command - trace_path - trace_exists - trace_size - pid or exit_code
- Continuous capture status returns:
- pid - running - target_exe - project_path - trace_path - trace_size - started_at
Notes
- v1 is Windows-first.
- v1 supports file-mode capture orchestration only.
- v1 does not control already-running UE instances or browse trace stores.
capture stopis a best-effort stop of the harness-launched process tree.capture snapshotis a best-effort filesystem snapshot of the active trace.
