sregulator_update_meter (sbroker v1.1.1)
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.See also: sregulator.
