Guidelines for collecting historical data

Follow the guidelines for collecting historical data and determining data collection rates.

If you use historical recording for dataset groups:
  • Collect only the data that you need.
  • Choose an appropriate data collection rate.

You can set historical data collection rates to:

  • Every minute
  • Every 5 minutes
  • Every 15 minutes
  • Every 30 minutes
  • Every 60 minutes
  • Every 1,440 minutes (every day)

If you choose a high frequency rate for collecting historical data:

  • Historical files fill up or wrap faster.
  • More processor and I/O resources of the IBM® Tivoli® Enterprise Monitoring Server are used.
