h2olog-quic-trace

A utility to prepare log data for google/quic-trace.

Prerequisites

• Python 3.5 or later
  • and its dependencies: pip3 install -r requirements.txt
• A BigQuery authentication file named authn.json
  • See https://cloud.google.com/bigquery/docs/reference/libraries to setup authentication
• A BigQuery table managed by h2olog-collector
  • See https://github.com/gfx/h2olog-collector for details

Usage

Fetch a specific set of logs from BigQuery

Assumed that there is a BigQuery table named h2olog.quic:

# find by xid
$ h2olog-quic-trace 'h2olog.quic' --xid 123456 > log.jsonl
# find by quicly connection id
$ h2olog-quic-trace 'h2olog.quic' --conn 123456 > log.jsonl

Transform .jsonl into QTR JSON files

$ $QUICLY/misc/quictrace-adapter.py log.jsonl qtr
Transforming qtr/2020-04-20T13:24:49Z-250194.json

where $QUICLY is the h2olog/quicly repository path.

Render a QTR JSON file

$ $QUIC_TRACE/bazel-bin/tools/render/render_trace qtr/2020-04-20T13:24:49Z-250194.json

where $QUIC_TRACE is the google/quic-trace repository path.

Then, you’ll see a QUIC trace viewer launched like this:
