Note
When you specify a PollerGroupName, multiple ESMs within the same Amazon VPC can share Event Poller Unit (EPU) capacity.
You can use this option to optimize Provisioned mode costs for your ESMs. Requirements for ESM grouping:
ESMs must be within the same Amazon VPC
Maximum of 100 ESMs per poller group
Aggregate maximum pollers across all ESMs in a group cannot exceed 2000
You can update the PollerGroupName to move an ESM to a different group, or remove an ESM from a group by setting PollerGroupName to an empty string ("").
