Methods defined here:
- IsChromeTracingSupported(self)
- Returns whether chrome tracing is supported.
- Start(self, trace_options, category_filter, timeout=10)
- Starts tracing.
trace_options specifies which tracing systems to activate. Category filter
allows fine-tuning of the data that are collected by the selected tracing
systems.
Some tracers are process-specific, e.g. chrome tracing, but are not
guaranteed to be supported. In order to support tracing of these kinds of
tracers, Start will succeed *always*, even if the tracing systems you have
requested are not supported.
If you absolutely require a particular tracer to exist, then check
for its support after you have started the process in question. Or, have
your code fail gracefully when the data you require is not present in the
resulting trace.
- Stop(self)
- Stops tracing and returns a TraceValue.
- __init__(self, tracing_controller_backend)
- Provides control of the tracing systems supported by telemetry.
Data descriptors defined here:
- __dict__
- dictionary for instance variables (if defined)
- __weakref__
- list of weak references to the object (if defined)
- is_tracing_running
