Great, Irina! The only problem is that the |

Yes! But I'm also not sure if this is correct statement about how increments work: I assumed feedback is 'rounded' to the nearest increment. (i.e. if CPU increases by 13% -- the limit will be reduced by 10%, but if increment = 5, the limit will be reduced by 15% -- is that right?)

Well, actually, if the jobs_sampler_cpu sampler is defined with no arguments, it will use the default {levels, [{80,1},{90,2},{100,3}]}. The algorithm tries to calculate some "average" per-cpu load, so 100 would be max. But given this setting, an average per-cpu load of 85% would give a sampler feedback of 1. That is, the levels algorithm (or jobs_sampler:calc(value, Levels, History) will pick the highest level where Value >= Level - in this case 80.

Thanks for looking at it Ulf! I'm moving my stuff into overview.edoc... |

Merged. Thanks! |

Thanks so much Ulf! BTW, I decided to remove NOTE 2 altogether because if I replace it with Cheers, On Mon, Apr 20, 2015 at 8:55 AM, Ulf Wiger notifications@github.com wrote:

Added 6 scenarios with corresponding jobs config examples -- largely based on my
Jobspresentation at Chicago Erlang Factory. Please note that I'm not 100% sure about NOTE 2 in Example 6.
