Common Artifacts for Performance Tests

Branch	Build Status
master

This repository has common artifacts to be used for Performance Tests.

In components, there are several Java projects and each project builds an executable JAR file.

The distribution directory has the scripts and the Maven project to build the final distribution package including all scripts and components to be used for performance tests.

The package (performance-common-distribution-${version}.tar.gz) built by the distribution maven module can be used as a dependency to write performance testing scripts.

This package only provides helper scripts and applications. You must extend the functionality of these scripts to run performance tests.

It's recommended to include the contents of this package with any scripts written to extend the functionality.

10 directories, 26 files

Each directory has one or more executable scripts. All scripts support -h (help) option.

Note: Most of these scripts will work only on Debian based systems like Ubuntu.

See following sections for more details.

AWS CloudFormation

The performance test scripts can create AWS resources to run standard server performance tests on AWS.

Standard server performance tests include a Back-end service and the parameters include "Application heap memory sizes", "Concurrent users", "Message sizes", and "Back-end Sleep Times".

The create-template.py script can create AWS CloudFormation template based on a Jinja2 template. The common_perf_test_cfn.yaml file is a common Jinja2 template, which has necessary configurations to create a performance test environment on AWS.

You should extend cloudformation-common.sh to run standard server performance tests. By extending, you can will get all the functionality of creating the AWS stack, run the tests, delete stack and summarize results. You can even run several stacks to run performance tests parallely.

The cloudformation-common.sh script is not directly executable, but it supports following options.

ubuntu@server:~$ ./cloudformation/cloudformation-common.sh -h

Usage: 
./cloudformation/cloudformation-common.sh -f <performance_scripts_distribution> [-d <results_dir>] -k <key_file> -n <key_name>
   -j <jmeter_distribution> -o <oracle_jdk_distribution> -g <gcviewer_jar_path>
   -s <stack_name_prefix> -b <s3_bucket_name> -r <s3_bucket_region>
   -J <jmeter_client_ec2_instance_type> -S <jmeter_server_ec2_instance_type>
   -N <netty_ec2_instance_type> 
   [-t <number_of_stacks>] [-p <parallel_parameter_option>] [-w <minimum_stack_creation_wait_time>]
   [-h] -- [run_performance_tests_options]

-f: Distribution containing the scripts to run performance tests.
-d: The results directory. Default value is a directory with current time. For example, results-20190124094422.

    Default: u. Allowed option characters: ubsm.
-w: The minimum time to wait in minutes before polling for cloudformation stack's CREATE_COMPLETE status.
    Default: 5.
-h: Display this help and exit.

When running the performance tests, you can use get-wum-updated-wso2-product.sh script to get a WSO2 product with all WUM updates.

Java

Use the install-java.sh script to install Oracle Java Development Kit (JDK) on 64bit Linux.

The install-java.sh script in this directory will not be useful when OpenJDK is used. It's recommended to use the default package repositories to install OpenJDK.

Currently install-java.sh script supports installing Oracle JDK 8.

You must download latest JDK 8.

This script can also install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy files. You need to copy JCE Policy zip file to the same location as the downloaded JDK file (tar.gz)

The script needs to be run as root. The JDK will be extracted to /usr/lib/jvm directory.

ubuntu@server:~$ ./java/install-java.sh -h

Usage: 
./java/install-java.sh -f <java_dist> [-p <java_dir>] [-u <user>] [-h]

-f: The jdk tar.gz file.
-p: Java installation directory.
-u: Target user. Default: ubuntu.
-h: Display this help and exit.

JMeter

Installing JMeter

The install-jmeter.sh script will extract JMeter, install Plugin Manager and copy the user.properties file.

The user.properties file has recommended configurations for performance tests.

There is an option to download latest Apache JMeter.

ubuntu@server:~$ ./jmeter/install-jmeter.sh -h

Usage: 
./jmeter/install-jmeter.sh -i <installation_dir> [-f <jmeter_dist>] [-d] [-p <jmeter_plugin_name>] [-h]

-i: Apache JMeter installation directory.
-f: Apache JMeter tgz distribution.
-d: Download Apache JMeter from web.
-p: The name of the JMeter Plugin to install. You can provide multiple names.
-h: Display this help and exit.

Running standard server performance tests.

You shoud extend perf-test-common.sh to run standard server performance tests. It supports testing with multiple concurrent users, different message sizes, different Back-end service delays and different heap memory sizes of the target server.

The script also supports running remote (distributed) JMeter tests and it will also summarize the results for warmup and measurement periods.

A script can extend this perf-test-common.sh script by simply sourcing the perf-test-common.sh script.

For example:

# Execute common script
. $script_dir/perf-test-common.sh

Any script depending on this script must define test scenarios as follows:

declare -A test_scenario0=(
    [name]="test_scenario_name1"
    [display_name]="Test Scenario 1"
    [description]="Description of Test Scenario 1"
    [jmx]="test_scenario_name1.jmx"
    [use_backend]=true
    [skip]=false
)
declare -A test_scenario1=(
    [name]="test_scenario_name2"
    [display_name]="Test Scenario 2"
    [description]="Description of Test Scenario 2"
    [jmx]="test_scenario_name2.jmx"
    [use_backend]=true
    [skip]=false
)

Then define following functions in the script.

initialize
before_execute_test_scenario
after_execute_test_scenario

In above functions, following variables may be used

scenario_name
heap
users
msize
sleep_time
report_location

Use jmeter_params array in before_execute_test_scenario to provide JMeter parameters.

In before_execute_test_scenario JMETER_JVM_ARGS variable can be set to provide additional JVM arguments to JMeter.

Finally, execute test scenarios using the function test_scenarios.

ubuntu@server:~$ ./jmeter/perf-test-common.sh -h

Usage: 
./jmeter/perf-test-common.sh -m <heap_sizes> -u <concurrent_users> -b <message_sizes> -s <sleep_times> [-d <test_duration>] [-w <warmup_time>]
   [-n <jmeter_servers>] [-j <jmeter_server_heap_size>] [-k <jmeter_client_heap_size>] [-l <netty_service_heap_size>]

-h: Display this help and exit.

Creating a summary

Use create-summary-csv.sh to create a summary CSV file.

ubuntu@server:~$ ./jmeter/create-summary-csv.sh -h

Usage: 
./jmeter/create-summary-csv.sh -n <application_name> [-c <column_header_name>] [-r <regex>] [-x] 
   [-p <file_prefix>] [-g <gcviewer_jar_path>] [-d <results_dir>]

Use csv-to-markdown-converter.py to convert CSV results into Markdown format.

ubuntu@server:~$ ./jmeter/csv-to-markdown-converter.py

Usage: {Input File(.csv)} {Output File (.md)}

Use create-summary-markdown.py to create a markdown file, which will be a summary of performance test results. This scripts looks for a Jinja2 template with the name summary.md in templates directory.

ubuntu@server:~$ ./jmeter/create-summary-markdown.py -h
usage: create-summary-markdown.py [-h] --json-files JSON_FILES
                                  [JSON_FILES ...] --column-names COLUMN_NAMES

  --json-files JSON_FILES [JSON_FILES ...]
                        JSON files with parameters.
  --column-names COLUMN_NAMES [COLUMN_NAMES ...]
                        Columns to include in the report.

JTL Splitter

The "jtl-splitter" directory has a Java program to split a single JTL file into warmup and measurement based on the number of minutes given as the warmup time.

When reporting the results for the performance tests, some specified number of minutes from the beginning of the test are considered as the "Java Warm-up Time" and the from the final results, the warm-up duration is excluded. By doing this, the results reported from the test will only consider the steady-state of the server.

This program should be invoked by the performance testing script after completing the JMeter performance test.

For example if you specify 5 minutes warmup-time, the JTL splitter splits the results.jtl file and the results-warmup.jtl file will have the test results for first 5 minutes. The results after 5 minutes will be in results-measurement.jtl.

ubuntu@server:~$ ./jtl-splitter/jtl-splitter.sh -h

Usage: 
./jtl-splitter/jtl-splitter.sh [-m <heap_size>] [-h] -- [jtl_splitter_flags]

-m: The heap memory size. Default: 1g
-h: Display this help and exit.
