Configuring robot failure tolerance

Updated on December 20, 2022

For robots that fail their assignments too often, configure work group-specific thresholds to stop the robot from working in the current work group if these specific thresholds are exceeded.

Pega Robot Manager stops every robot that reaches or exceeds any of the failure thresholds.
  1. In the navigation pane of Pega Robot Manager, click Unattended RPAWork groups.
  2. Select the work group whose failure thresholds you want to modify.
  3. In the Settings widget, click the Edit icon.
  4. Optional: To modify the failure thresholds for the robots in the work group, update the properties you want to change:
    • To modify the number of consecutive failed assignments that the assignment type can accept for each robot within the alert evaluation time, update the Consecutive failures property value. The default value is 5.
    • To modify the percentage of failed assignments that the assignment type can accept for each robot within the alert evaluation time, update the Failed automations threshold per robot (%) property. The default value is 20.
    See the following figure for reference:
    Setting the failure thresholds for a work group
    Setting failure thresholds for a work group
  5. Optional: To prevent robots from stopping based on threshold settings for consecutive failures and failed automations, complete the following steps:
    1. In the Consecutive failures field, enter -1 or any negative value.
    2. In the Failed automations threshold per robot (%) field, enter 101 or any value above 100.
    Caution: Enabling Robot Manager to stop underperforming robots is the most efficient solution for preserving the integrity of the cases in assignments and completing the work successfully within the required service-level agreements (SLAs). Only disable these settings if this meets your business needs.
  6. Click Submit to confirm your settings.
  7. Optional: Review the intervals that are related to failure thresholds, and adjust values as needed based on your business objectives.
    For example: You can determine how long a robot can remain in the APPLICATION NOT READY state before being shut down, or how long to prevent an underperforming robot from moving between work groups and performing additional assignments.
    For more information, see Configuring robot intervals.
  8. Optional: Adjust the default notification thresholds to your business needs.
    With meaningful notification thresholds, you can learn about robots that are approaching a failure threshold through web gadget or email notifications. This way, you can attend to a failing robot before Robot Manager stops that robot. For more information, see Configuring notification thresholds.
