Collection Services

Collection Services provides for the collection of system and job level performance data. It is the primary collector of performance data.

Collection Services samples system and job level performance data continuously and automatically with minimal system overhead. It can collect data at regular time intervals of 15 seconds up to 1 hour (default is 15 minutes).

Data is collected from many system resources, such as:

  • CPU
  • Memory pools
  • Disk (internal and external)
  • Communications

Use Collection Services performance data to:

  • Monitor how your system is running
  • Investigate a reported performance problem
  • Understand resource usage and how it changed over time

Collection Services can be configured and managed through the IBM® Navigator for i Performance interface or CL commands.
