The flap module determines how often a check has flapped, that is, how often the return code changed in the period examined For example, a check that completed as follows:
  1. MODEXEC_OK
  2. MODEXEC_OK
  3. MODEXEC_OK
  4. MODEXEC_PROBLEM
  5. MODEXEC_OK
  6. MODEXEC_OK
  7. MODEXEC_PROBLEM

The flap module utilizes check records.
