UC_PERFORMANCE_THRESHOLDS - Performance Check

This Variable (VARA) object defines the settings that allows the system to measure performance incidents. It is supplied with system Client 0 and its settings apply to the whole Automation Engine system. For more information, see System Performance.

The default values are used if the variable is left empty (no key/value pair definition). If the performance metrics surpass the thresholds that have been defined here, a corresponding warning is displayed in the Automic Web Interface, namely:

  • "System might not meet minimum requirements. Please check your infrastructure (Automation Engine, database, network). for the system requirements

  • "Message queue threshold exceeded: <queue1, queue2>" for message queues (aggregated)

If one or both of these messages appear, contact the database or system administrator so that the system's performance can be optimized. Once the performance improves, the warning disappears automatically after the next measurement.

Important! This function can only be deactivated for the message queues, not for the database as these measurements are crucial for the system's performance. As a system or database administrator, make sure you mitigate the issue by optimizing the system, not by changing the thresholds defined here. However, if necessary, you can adapt them.
