      • getDropOverloadsList

        public List<ClusterLoadAssignment.Policy.DropOverload> getDropOverloadsList()
         Action to trim the overall incoming traffic to protect the upstream
 hosts. This action allows protection in case the hosts are unable to
 recover from an outage, or unable to autoscale or unable to handle
 incoming traffic volume for any reason.
 At the client each category is applied one after the other to generate
 the 'actual' drop percentage on all outgoing traffic. For example:
 .. code-block:: json
  { "drop_overloads": [
      { "category": "throttle", "drop_percentage": 60 }
      { "category": "lb", "drop_percentage": 50 }
  ]}
 The actual drop percentages applied to the traffic at the clients will be
    "throttle"_drop = 60%
    "lb"_drop = 20%  // 50% of the remaining 'actual' load, which is 40%.
    actual_outgoing_load = 20% // remaining after applying all categories.

      • hasOverprovisioningFactor

        public boolean hasOverprovisioningFactor()
         Priority levels and localities are considered overprovisioned with this
 factor (in percentage). This means that we don't consider a priority
 level or locality unhealthy until the fraction of healthy hosts
 multiplied by the overprovisioning factor drops below 100.
 With the default value 140(1.4), Envoy doesn't consider a priority level
 or a locality unhealthy until their percentage of healthy hosts drops
 below 72%. For example:
 .. code-block:: json
  { "overprovisioning_factor": 100 }
