Log a message on every change of demand

Parameters:

  • name – name of the logging.Logger to log to

  • message – format for message to emit on every change

  • level – numerical logging level

The message parameter is used as a %-style format string with named fields. Valid named format fields are

value

for the new demand being set,

demand, supply, utilisation and allocation

for the current state of target, and

target

for the target pool itself.

For example, a message of "adjust demand from %(demand)s to %(value)s" will log the old and new demand value.

Deprecated since version 0.12.2: The consumption format field. Use allocation instead.
