tracy-import-chrome(1)

NAME
tracy-import-chrome - Import chrome trace data into tracy

SYNOPSIS
tracy-import-chrome input.json output.tracy

DESCRIPTION
The following chrome-tracing phases are supported:

    b/B/e/E - Timeline events such as ZoneNamed X - Timeline events such as ZoneNamed i/I - Message events such as TracyMessage * Messages containing the word "frame" are interpreted as frame events such as FrameMarkNamed C - Plot events such as TracyPlot M - Metadata of type "thread_name" is used to name threads

Tracy can import traces compressed with the Zstandard algorithm (for example, using the zstd command-line utility). Traces ending with .zst extension are assumed to be compressed.

Chrome tracing format doesn't document a way to provide source location data. The import-chrome and import-fuchsia utilities will however recognize a custom loc tag in the root of zone begin events. You should be formatting this data in the usual filename:line style, for example: hello.c:42. Providing the line number (including a colon) is optional but highly recommended.

LIMITATIONS

•   Tracy is a single-process profiler. Should the imported trace contain PID entries, each PID+TID pair will create a new pseudo-TID number, which the profiler will then decode into a PID+TID pair in thread labels. If you want to preserve the original TID numbers, your traces should omit PID entries.

•   The imported data may be severely limited, either by not mapping directly to the data structures used by Tracy or by following undocumented practices.
