Load Test Tool Client/Host

Creating a RHEL AWS instance

  • Pick a Region then Create Instance > Launch Instance
  • Follow the prompts to create a basic, RHEL-flavored instance
  • Use of the QA/Dev key pairs that have been set up for this:
    • US East Key Pair: QA-Dev-Share (created by jbonacci) for general use
    • US West Key Pair: QA-dev-share (created by RaFromBRC) for general use
  • Once the instance is running, log in as "ec2-user"
  • The following apps, tools, and libs will need to be installed for use with various Services applications:
    • gcc, gcc-c++
    • hg
    • git
    • python-devel
    • automake, autoconf, and libtool (required for libzmq, for easy_install)
    • pip
    • virtualenv
    • node/npm
    • zeromq 3.X
    • gmp, gmp-devel
  • Also, general rhel updates:
$ sudo yum -y update
and/or
$ sudo yum -y upgrade
  • Now, the instance should be ready for installing and using the Loads tool.

Creating an Ubuntu AWS instance

  • Pick a Region then Create Instance > Launch Instance
  • Follow the prompts to create a basic, Ubuntu-flavored instance
  • Use of the QA/Dev key pairs that have been set up for this:
    • US East Key Pair: QA-Dev-Share (created by jbonacci) for general use
    • US West Key Pair: QA-dev-share (created by RaFromBRC) for general use
  • Once the instance is running, log in as "ubuntu"
  • The following apps, tools, and libs will need to be installed for use with various Services applications:
    • gcc, g++
    • mercurial
    • git
    • python-setuptools, python-virtualenv, and python-dev
    • automake, autoconf, libtool
    • m4
    • node/npm
    • libzmq and zeromq 3.X
    • gmp-5.1.3 or newer
  • Also, general rhel updates:
$ sudo apt-get update
and/or
$ sudo apt-get upgrade
  • Now, the instance should be ready for installing and using the Loads tool.

Installing Loop-Server and the Loads tool on the AWS instance

  • Installation:
TBD
  • Note: This will install a local copy of the Loads tool for use with the Loop-Server.

Running the load test against the Loop-Server in Stage

  • Stage environment:
$ make test
or
$ make test SERVER_URL=BLAH
$ make bench
or
$ make bench SERVER_URL=BLAH

Using the Loads Services Cluster for the Loop-Server in Stage

  • By using the Loads Services Cluster, we can offload the broker/agents processes and save client-side CPU and memory.
  • Changes were made to Makefile and the load test to use the cluster and some associated config files (for test, bench, megabench).
  • Stage environment:
$ make megabench SERVER_URL=BLAH
  • Dev environment: TBD
  • Production environment: TBD

Installing MSISDN-Gateway and the Loads tool on the AWS instance

  • Installation:
TBD
  • Note: This will install a local copy of the Loads tool for use with MSISDN-Gateway.

Running the load test against MSISDN-Gateway in Stage

  • Stage environment:
$ make test SERVER_URL=BLAH
$ make bench SERVER_URL=BLAH

Using the Loads Services Cluster for the MSISDN-Gateway

  • By using the Loads Services Cluster, we can offload the broker/agents processes and save client-side CPU and memory.
  • Changes were made to Makefile and the load test to use the cluster and some associated config files (for test, bench, megabench).
  • Stage environment:
$ make megabench SERVER_URL=BLAH
  • Dev environment: TBD
  • Production environment: TBD

Configuring The Load Tests

Test Coverage and Stats

  • Basic tweakable values for all load tests
    • users = number of concurrent users/agent
    • agents = number of agents out of the cluster, otherwise errors out
    • duration = in seconds
    • hits = 1 or X number of rounds/hits/iterations
  • Loop-Server
    • TBD
  • MSISDN-Gateway
    • TBD

Analyzing the Results

  • There are several methods and tools for analyzing the load test results.

Debugging the Issues

  • There are several methods and tools for debugging the load test errors and other issues.
  • 1. Important logs for Loop-Server (per server)
    • TBD
  • 2. Important logs for MSISDN-Gateway (per server)
    • TBD
  • Acceptable Loop-Server errors:
TBD
  • Acceptable MSISDN-Gateway errors:
TBD
