About

A docker-compose version of a benchmark on the Envoy proxy with Redis backend using Redis-benchmark and MemTier-benchmark.

WIP

This project is a work in progress. The implementation is incomplete and subject to change. The documentation can be inaccurate.

How to run:

In this directory, as a preparatory step, you need to create the directory where the results be left:

  [[ ! -d ./proxy_results ]]   && \
       mkdir ./proxy_results   && \
       sudo chown root: ./proxy_results

Then, afterwards, in this directory, run:

  docker-compose pull
   
  docker-compose up --build -d

Results left by a run:

The results of the tests will be left in the proxy_results/ directory. (If another directory is needed, please modify docker-compose.yaml.) The result files left by each docker-compose up of the test containers are (<common_suffix> below is a common suffix generated from the container-id and initial epoch at the start of the docker-compose up, and is common among all log files of the same run):

envoy_redis_stats_<common_suffix>.log

The Envoy stats at the end of each Sysbench test, from http://localhost:8001/stats

envoy_redis_log_<common_suffix>.log

The Envoy debug logs.

script_redis_trace_<common_suffix>.log

The test script logs itself (contains Perf and SysBench messages).

envoy_redis_perf_<common_suffix>.data

The Perf-Record file during the Sysbench tests.

envoy_redis_perf_<common_suffix>.script.txt.xz

The Perf-Script text file generated (with symbol names) from the Perf-Record file above.

How to generate final flame graphs:

Note: To generate (externally, after the containers have run) the FlameGraph, use the envoy_redis_perf_<common_suffix>.script.txt.xz file with the symbol names:

   xzcat 'proxy_results/envoy_redis_perf_<common_suffix>.script.txt.xz' | \
        ${your_flamegraph_install_dir}/stackcollapse-perf.pl | \
        ${your_flamegraph_install_dir}/flamegraph.pl > envoy_flamegraph.svg

It is possible to run differential flame graphs for performance regression testing on two different versions of the same Envoy filter, e.g., in a continuous integration (CI). See the argument ENVOY_TAG_VERSION in Dockerfile-proxy:

   ARG ENVOY_TAG_VERSION=latest
   FROM envoyproxy/envoy-debug-dev:$ENVOY_TAG_VERSION

, e.g., to do a performance regression testing between ENVOY_TAG_VERSION=85a8570cd0530402de21c48c6688dddb187775d5 and ENVOY_TAG_VERSION=6c672b75b1be59676bc5f576af96323e6c626a03.

   xzcat 'proxy_results/envoy_redis_perf_<first_version>.script.txt.xz' | \
        ${your_flamegraph_install_dir}/stackcollapse-perf.pl  > v1.folded
    
   xzcat 'proxy_results/envoy_redis_perf_<second_version>.script.txt.xz' | \
        ${your_flamegraph_install_dir}/stackcollapse-perf.pl  > v2.folded
    
   ${your_flamegraph_install_dir}/difffolded.pl v1.folded v2.folded | \
        ${your_flamegraph_install_dir}/flamegraph.pl > perfrm_regr_test.svg
