Description

Motivation

We observed that e.g. petrol is running 8 openQA worker instance which with 16 logical cores leaves no headroom for the system. Probably we need to lower that number

Acceptance criteria

  • AC1: diesel+petrol+mania consistently do not alert on too high system load
  • AC2: diesel+petrol+mania use an efficient number of instances, i.e. the highest number possible

Suggestions

  • Try a lower load limit threshold
  • Reduce number of instances
  • Monitor
