Internal

Methodology

Set up the performance testing environment.

Platform

Map it (Performance Testing Environment.odg)- get a diagram that shows:

  • Hosts (names, IP addresses/subnet masks, external ports).
  • Represent all network interfaces and their connectivity to various networks. It helps to understand how the hosts are interconnected - on the diagram.
  • Represent processes
    • Load Agent
    • Proxy
    • Application Server
    • Database
  • Document the procedures to stop/start the processes - some load tests may need the processes to be completed shut down and restarted. Usually there's an "Environment" document associate with the environment where all these procedures are documented.
  • Encode log locations as aliases (al, jbl, etc.)
  • If the target are Windows machines, it's a good idea to install Cygwin - it'll improve productivity and provide a lot of good tools.
  • Annotate the environment diagram with the RAM and CPU amount on each host.

Web Proxy

Application Server

  • Identify the application server configuration file and its location on disk.
  • Represent the database connection pools and the connections to their respective databases.

Database

Distribute in the Right Place

  • Put in place monitoring for CPU, physical RAM, open file descriptors and other system resources.
