Steps for demo

1. Zoom out to show the full globe activity
2. Explain
   1. Fixed lines are active data links, where GREEN is good status, YELLOW warning status, RED critical status
   2. Blue lines showing up from time to time are processing jobs being picked up by worker nodes
3. Zoom in: to the site of their choice if they have a specific one, to the Europe region if they don't
4. Explain

QAOES

The tool is available via the web interface [[http://dashb-cms-mining-devel.cern.ch/dashboard/request.py/qaoes][QAOES]

Steps for demo

1. load the page and select the 3 input parameters
2. explain the 3 parameters:
   1. timerange: the input data for the Association Rule mining is job monitoring data taken from the past x hours. Choices are: 6, or 12 hours.
   2. minimum number of jobs, called "minimum support": it is the minimum percentage of jobs in the input data that has to contain all the job attributes, in order to generate a rule. The value is given in percent, so between 0 and 100. Choices in the interface are: 0.1%, 0.5%, 1%.
   3. confidence: states how significant the rules have to be. It is the percentage of how many jobs which contain the job attributes of the antecedent also contain the job attributes of the consequent.
3. click "show rules" and explain the output:
   1. in general: a rule is an implication A => C, the left-hand-side is also called antecedent, the right-hand-side consequent. In the output the rules are listed as "components" => "Error Code"
   2. there are three values for each rule (line):
