16. Index to filter Environment under test Environment ID: •  Data center region 15 App under test •  Version & Release ID •  Jenkins job ID •  Node ID •  Component •  Module •  Class •  Developer •  Log level Load Test rig •  Test rig version •  Server host name •  Load script name •  Load script version
17. Recap • Reach for higher maturity • Group similar metrics in same location. • Identify early warning leading indicators. • Calculate ratios. • Identify thresholds to act on early warning signals. • Automate manual “air traffic control”. 16
