sregulator_update_meter (sbroker v1.1.2)

Updates a list of regulators with the relative time of either queue.

sregulator_update_meter can be used as a sbroker_meter in a sbroker or a sregulator. It will update a list of regulators with the relative time (in native time units) of a specified queue at random intervals, ignoring any regulators that are not alive. Its argument, spec(), is of the form:
  [{Regulator :: sregulator:regulator(),
    Queue :: ask | ask_r,
    Config :: #{update => Update :: pos_integer()}}, ...].
Regulator is a regulator process to update with the approximate relative time of queue Queue with updates uniformly distributed from 0.5 * Update to 1.5 * Update milliseconds (defaults to 100). This random interval is used to prevent synchronisation of update messages and their side effects, see reference.
