GUIDED EXPLORATION Fixing Memory Problems In Production 14

GUIDED EXPLORATION Detection describes the task of automatically detecting a potential problem, i.e., a suspicious pattern. Fixing Memory Problems In Production 14

GUIDED EXPLORATION Detection describes the task of automatically detecting a potential problem, i.e., a suspicious pattern. Highlighting the relevant region on the UI helps users to understand where the automatically gained insight can be found if the view was inspected manually. Fixing Memory Problems In Production 14

Explanation of the highlighted visualization helps users to interpret it and explains concepts that are needed for this interpretation. Suggestions on which steps could / should be taken next make it easier for the user to understand what operations are possible and why they might be useful. Fixing Memory Problems In Production 14

DEMO: EVOLUTION Fixing Memory Problems In Production 19

DEMO: EVOLUTION Fixing Memory Problems In Production 20

DEMO: EVOLUTION Date objects allocated in the constructor of Base are the major suspects for a memory leak since about 30% of the overall heap growth is accounted to them. Inspect who keeps them alive. Fixing Memory Problems In Production 20
