Configuration

Property Default Description
duration 90 Specifies the length of time in seconds to fire off user scenarios.
users_start 500 The starting number of users per drupal_web instance.
users_step 200 The number of users to add per drupal_web instance after each successful iteration.

Example configuration:

standard_drupal:
  workload: drupal
  duration: 90
  users_start: 500
  users_step: 200
  instances:
    - roles:
        - drupal_mysql_master
    - roles:
        - drupal_mysql_slave
    - roles:
        - drupal_gatling
    - roles:
        - drupal_web
    - roles:
        - drupal_web
    - roles:
        - drupal_web
    - roles:
        - drupal_web

In the above example, Gatling will ramp 500 users over 90 seconds to each of the 4 drupal_web instances on the first iteration. If the iteration is successful, the next iteration will be 500 + 200 users to each of the 4 drupal_web instances.

Requirements

  • 1 drupal_mysql_master instance
  • 1 drupal_gatling instance
  • At least one drupal_web instance
  • A drupal_mysql_slave instance is optional
  • It is preferred that the drupal_web instances can communicate with the drupal_mysql_master instances over a separate network, but it is not necessary
