Description

Ideas

  • 1. Detect from monitoring data which monitored machines show a too low CPU usage over time
  • 1.1. Just detection -> #158377
  • 1.2. Switch off the machines automatically identified in 1.1. -> #158380
  • 2. Identify "unused" but still powered machines
  • 2.1. Crosscheck which machines marked as "unused" in racktables are still pingable (as they should not be powered on at all) -> #158383
  • 2.2. Crosscheck which machines marked as "unused" in racktables still draw power according to ePDU data (as they should not be powered on and wasting significant power at all) -> #158386
  • 3. Identify underused machines from too low networking data, e.g. from switch bandwidth measurements -> #114622
