Module: TestingMemory

Defined in:
lib/testing_memory/testing_memory.rb

Overview

Runs a memory test:

  1. Run content server or backup server

  2. Generate files.

  3. Monitor files.

  4. Index files.

  5. Report memory of proces at different phasestimes

Examples:

testing_server --conf_file=~/.bbfs/etc/backup_testing_memory.yml --server_to_test=backup
testing_server --conf_file=~/.bbfs/etc/content_testing_memory.yml --server_to_test=content
