Table 12.48. New options
Option = default value | (Type) Help string | |
[DEFAULT] batch_polled_samples = True | (BoolOpt) To reduce polling agent load, samples are sent to the notification agent in a batch. To gain higher throughput at the cost of load set this to False. | |

We are going to remove it in the N release, but we must keep backward compatible at the same time. This option provides such compatibility - it defaults to False in Liberty and can be turned on for early adopters with a new installations or for testing.
