Cloud Trace API - Module Google::Cloud::Trace::LabelKey (v0.42.2)

Reference documentation and code samples for the Cloud Trace API module Google::Cloud::Trace::LabelKey.

A collection of well-known label keys for trace spans.

Methods

.set_stack_trace

def self.set_stack_trace(labels, stack_frames: nil, skip_frames: 1, truncate_stack: nil, filter_stack: nil)

Set the stack trace label in the given labels hash. The current call stack is formatted so the Stackdriver UI will display it.

Parameters

labels (Hash) — The labels hash in which to set the stack trace label value.
stack_frames (Array<Thread::Backtrace::Location>) (defaults to: nil) — The current caller stack as returned from ::Kernel.caller_locations. If not set, ::Kernel.caller_locations is called internally.
skip_frames (Integer) (defaults to: 1) — Passed to the internal invocation of ::Kernel.caller_locations if one is needed.
truncate_stack (Proc) (defaults to: nil) — A procedure that allows skipping of the "topmost" stack frames. Stack frames, represented by instances of Thread::Backtrace::Location, are passed to this proc beginning with the topmost frame. As long as the proc returns a falsy value, those frames are dropped. Once the proc returns true for the first time, that frame and all remaining frames (possibly subject to filter_stack) are used. If not set, no frames are skipped.
filter_stack (Proc) (defaults to: nil) — A procedure that allows skipping of stack frames in the middle of the stack trace. After possibly skipping frames using truncate_stack, all remaining frames are passed to this proc as Thread::Backtrace::Location objects. Those for whom the proc returns a falsy value are skipped. If this parameter is not set, no filtering is done and all frames are presented in the stack trace.

Example

require "google/cloud/trace"

trace_record = Google::Cloud::Trace::TraceRecord.new "my-project"
span = trace_record.create_span "root_span"
Google::Cloud::Trace::LabelKey.set_stack_trace span.labels
