Customize timeouts in the Batch Monitor process

Adjust the TimeSpan timeout variables in the FlexiCapture Batch Monitor process for UiPath, including EmptyQueueTimeoutDuration, to tune transaction throughput.

Timeout variables

The Batch Monitor process uses three TimeSpan-type variables to set timeout lengths.

Variable name	Purpose	Default value
EmptyQueueTimeoutDuration	How long the next attempt to get a transaction from the Monitor Queue is postponed when the queue holds no documents	15 seconds
VerificationStagePostpone	How long the next batch stage check is postponed for the current transaction when the batch was at the Verification stage at the time of the check	2 minutes
OtherStagePostpone	How long the next batch stage check is postponed for the current transaction when the batch is at none of the Processed, Exceptions, or Verification stages	1 minute

Increasing VerificationStagePostpone and OtherStagePostpone can increase the total volume of processed transactions.

Modify the timeout values

1. Open the process variables

   Open the Batch Monitor process in UiPath Studio, navigate to the State Machine area, and expand the Variables pane.

2. Adjust the empty-queue timeout

   Modify the value of EmptyQueueTimeoutDuration to decrease or increase the time between attempts to get a transaction when the queue is empty.

3. Adjust the postpone timeouts

   If the Batch Monitor process cannot check the whole queue in time because of a large number of delayed transactions, increase the values of VerificationStagePostpone and OtherStagePostpone.

   
4. Republish the process

   Publish the process to Orchestrator again.
