# dial9 Tokio Runtime Telemetry Configuration
# ============================================================================
# dial9 captures Tokio runtime-level events (poll start/end, worker park/unpark,
# task spawn/terminate) into binary trace segments. It sees executor-level faults
# — a long poll stalling a worker, a task that never yields — that request-level
# metrics and spans cannot.
#
# This is an on-demand profiler, not always-on telemetry:
#
# - The stock binary does NOT support it. Build with `make build-profiling`,
#   which enables the `dial9` feature and `--cfg tokio_unstable`. Setting the
#   variables below on a stock binary logs a warning and changes nothing.
# - Trace segments are written continuously, and the oldest are deleted once
#   MAX_FILE_SIZE * ROTATION_COUNT bytes are retained. Under a high poll rate
#   that budget can wrap in minutes — size it against the window you need.
# - Turn it off again when the investigation is over.
#

# - Already encoded content (gzip, br, deflate, zstd) is automatically skipped
# - Minimum size threshold prevents compression of small files where overhead > benefit
# - Wildcard patterns supported in MIME types (e.g., text/* matches text/plain, text/html, etc.)
