Benchmark Utilities for AWS

These utilities create instances and run tests in your AWS account

Prerequisites

  • You must have the aws cli installed. If aws is not on your path then you can try to install it with pip3 install awscli --upgrade --user. See Amazon's aws cli installation instructions

  • You must also set your secret key for the CLI. You must set up a profile named geode-benchmarks, so use the command aws configure --profile geode-benchmarks to configure the CLI. You will need to specify the “AWS Access Key ID” and “AWS Secret Access Key,” which can be obtained from a team member. Set the “Default region name” to “us-west-2”. See Amazon's instructions

    Alternately, if you already have AWS credentials and just need to create the geode-benchmarks profile, you can first modify your existing AWS credentials file (found at ~/.aws/credentials) and add the following lines:

      [geode-benchmarks]
  aws_access_key_id = Your access ID key
  aws_secret_access_key = Your secret access key

    Then modify the config file found in the same directory and add the following:

      [profile geode-benchmarks]
  region = us-west-2

Image

If you need to build the image, you must have packer installed. The following scripts (launch, run, analyze, destroy) can be run without building the image. Build the image in the image directory using the build_image.sh script.

Using Environment Variables For configuration

In order to have the scripts know which configuration data to use, the data must be provided. One of the ways that can be done is via environment variables.

prompt> aws configure
AWS Access Key ID [****************foo1]:
AWS Secret Access Key [****************bar2]:
Default region name [us-west-2]:

Export environment variables as follows.

export AWS_ACCESS_KEY_ID=myaccesskeyfoo1
export AWS_SECRET_ACCESS_KEY=mysecretaccesskeybar2
export AWS_REGION="us-west-2"

Example

Example 1 - Generating and comparing two benchmark runs using run_tests.sh and analyze_tests.sh.

The first command creates a new cluster with 4 instances and the tag “mycluster” using launch_cluster.sh.

The second command runs only the MyCustomBenchmark benchmark test (by using the -- --tests=MyCustomBenchmark argument) found on the myBenchmarkBranch branch of the myGit/geode-benchmarks repository. This benchmark runs against the develop branch of Geode, adds some metadata, and outputs the results to ~/benchmarking/baseline using run_test.sh.

The third command runs the same benchmark against the myGeodeBranch branch of the myGit/geode repository and outputs the results to ~/benchmarking/branch using run_tests.sh.

The fourth command compares the results found in ~/benchmarking/branch to the results found in ~/benchmarking/baseline and outputs analysis of the operations per second and latency of the branch benchmark relative to the baseline using analyze_tests.sh.

The fifth command destroys the cluster using destroy_cluster.sh.

./launch_cluster.sh --tag mycluster --count 4
./run_tests.sh --tag mycluster --geode-branch develop --benchmark-repo myGit/geode-benchmarks --benchmark-branch myBenchmarkBranch --metadata "'name':'HelenaTestingCPUs','CPU':'256','geodeBranch':'CPUTest'" --output ~/benchmarking/baseline -- --tests=MyCustomBenchmark
./run_tests.sh --tag mycluster --geode-repo myGit/geode --geode-branch myGeodeBranch --benchmark-repo myGit/geode-benchmarks --benchmark-branch myBenchmarkBranch --metadata "'name':'HelenaTestingCPUs','CPU':'256','geodeBranch':'CPUTest'" --output ~/benchmarking/branch -- --tests=MyCustomBenchmark
./analyze_tests.sh --branch ~/benchmarking/branch --baseline ~/benchmarking/baseline
./destroy_cluster.sh --tag mycluster

Example 2 - run_against_baseline.sh:

./launch_cluster.sh --tag mycluster --count 4
./run_against_baseline.sh --tag mycluster --geode-branch develop --benchmark-branch benchmarkBranch --metadata "'name':'HelenaTestingCPUs','CPU':'256','geodeBranch':'CPUTest'"
./destroy_cluster.sh --tag mycluster

Running with Profiler

Prerequisites

  • You must have fulfilled the prerequisites at the beginning of this doc
  • You must have YourKit installed
  • Launch YourKit
  • In the top menu bar, select Filters... under the Settings dropdown
    • Uncheck the filter with the name org.apache
    • Click the Ok button to save the configuration
      • About this setting: When this box is checked, classes in the org.apache namespace will not be profiled, so it must be unchecked to profile geode or geode-benchmarks
  • Quit YourKit
  • Use your chosen text editor to edit your /Users/<yourUsername>/.yjp/ui.ini and add -Dyjp.zero.time.methods=false. Restart the profiler for this change to take effect.
    • About this setting: When this value is set to true, Unsafe Park and Unsafe Wait are ignored, which results in Reentrant Locks not appearing in the profiler. Setting this value to false will result in some noise from pools that are waiting for work, but is also necessary in order to see contention around reentrant locks.

Running in AWS

  • Launch YourKit
  • On the YourKit “Welcome” page, under the “Monitor Applications” section, hit the green plus to add a configuration
  • In the configuration window, fill in the following:
    • Connection name: some name for the configuration (the name of the member that is being connected is usually a good choice)
    • Host or IP Address: the public IP of the AWS VM hosting the member with which you want to connect (the launch cluster script prints these in the order that they were started: [locator-0, server-1, server-2, client-3])
    • Select Advanced and fill in the following:
      • SSH User: geode
      • SSH port: 22
      • Click on “Authentication Settings...” and on that window, fill in the following:
        • Authentication method: private key
        • Private Key: /Users/<yourUsername>/.geode-benchmarks/<clusterTag>-privkey.pem
        • Passphrase: leave blank
  • Once you have saved the configuration, it should show up under the “Monitor Applications” section of the page with the connection status. If the machines are running, the status should be “No applications running”. If there is a test in progress, you should be able to click through to monitor the test.
  • Pull up a terminal and navigate to geode-benchmarks/infrastructure/scripts/aws
  • Copy the YourKit file to the AWS VMs using the following command
    • ./copy_to_cluster.sh -tag <clusterTag> -- <path to libyjpagent.so> <destination path>
    • Your path to the libyjpagent.so is probably /Applications/YourKit-Java-Profiler-2019.1.app/Contents/Resources/bin/linux-x86-64/libyjpagent.so
    • Your destination path should probably be ., which will end up putting the file at /home/geode/
  • Run the test using the run_tests.sh script, with the additional CLI option -Pbenchmark.profiler.argument:
    • ./run_tests.sh --tag <clusterTag> [other CLI options] -- -i -Pbenchmark.profiler.argument=-agentpath:/home/geode/libyjpagent.so=disablestacktelemetry,exceptions=disable,delay=60000,sessionname=JVM_ROLE-JVM_ID
  • Return to YourKit and profile as usual

Example

./launch_cluster.sh --tag profiling --count 4
./copy_to_cluster.sh --tag profiling -- /Applications/YourKit-Java-Profiler-2019.1.app/Contents/Resources/bin/linux-x86-64/libyjpagent.so .
./run_tests.sh --tag profiling --geode-branch develop -- -i -Pbenchmark.profiler.argument=-agentpath:/home/geode/libyjpagent.so=disablestacktelemetry,exceptions=disable,delay=60000,sessionname=JVM_ROLE-JVM_ID
./destroy_cluster.sh --tag profiling

Running with SSL enabled

To run benchmarks with SSL enabled, run the test using the run_tests.sh script, with the additional CLI option -PwithSsl:

./run_tests.sh --tag <clusterTag> [other CLI options] -- -PwithSsl
