The following are illustrative examples. After you set up Application Insights for your project and your app generates a certain amount of data, smart detection takes 24 hours to learn the normal behavior of your app. The first was illuminating waterways made treacherous by shoals, reefs, rocks and other hazards as ships left the open ocean and pulled into port. Also, to keep track of where other ideas came from. Although metric alerts tell you there might be a problem, smart detection starts the diagnostic work for you. xmp.iid:7afe3aec-48e0-42f3-90fe-a658f844449c But in reality, light keepers were responsible for saving many lives [source: United States Coast Guard]. /LineHeight 10.0 82 0 R 83 0 R 83 0 R 83 0 R 83 0 R 83 0 R 83 0 R 83 0 R] May be used to define distinctive color difference of two adjoining sectors, or an obscured sector. /O /Layout ), Keeper: The person who takes care of the light in the lighthouse. /Type /StructTreeRoot The Lighthouse Emergency Signal: Once lost in wilderness, you have to do everything to be found as soon as possible by search and rescue teams.
