To conserve resources, vRealize Automation limits the number of concurrently running instances of machine provisioning and data collection. You can change the limits.
Configuring Concurrent Machine Provisioning Multiple concurrent requests for machine provisioning can impact the performance of vRealize Automation . You can make some changes to limits placed on proxy agents and workflow activities to alter performance.
Configuring Concurrent Data Collections By default, vRealize Automation limits concurrent data collection activities. If you change this limit, you can avoid unnecessary timeouts by changing the default execution timeout intervals for the different types of data collection.
Adjust Concurrency Limits and Timeout Intervals You can change the per-agent limits on concurrent provisioning, data collection activities, and the default timeout intervals.
Adjust Execution Frequency of Machine Callbacks You can change the frequency of several callback procedures, including the frequency that the vRealize Automation callback procedure is run for changed machine leases.
