CDH usage statistics in Pega Predictive Diagnostic Cloud
The
landing page provides statistics and detailed data about Pega Customer Decision Hub™ and lets you check the business usage and load patterns in your Customer Decision Hub applications. With this information, you can better plan and optimize the use of resources in your system, which is especially useful for a system administrator or an account executive. For example, if strategy execution times become longer and event processing rates decrease, you might need to increase the processing capacity of your system.You can access this information for all your systems with the following Pega Platform™ versions:
• For Pega Platform 8.6, version 8.6.1 and later
• For Pega Platform 8.5, version 8.5.5 and later
• For Pega Platform 8.4, version 8.4.6 and later
metrics data in PDC is aligned with Customer Decision Hub taxonomy components from the Customer Decision Hub framework. With the landing page, you can correlate metrics data with business related components, for example, a real-time container that is associated with the Next-Best-Action Designer. For more information, see Next-Best-Action Designer taxonomy.
Every hour, the PDC monitoring agent in your application sends Customer Decision Hub usage data to PDC. Customer Decision Hub metrics measure the count of decisions, events, and actions that your customers perform, and captures the response times for each interaction of the customer in your application. By automatically processing and aggregating this data at 15-minute intervals, PDC helps you to identify the application features that cause the particular usage patterns that PDC observes. This monitoring capability helps you with capacity planning, determining the throughput of your system, and configuring the performance parameters. To help you better manage the Customer Decision Hub data, you can export the results of each metric as CSV files.
The following table lists the metrics that you can monitor:
Metric | Information |

Configuring Customer Decision Hub metrics for non-production environments
PDC can also capture Customer Decision Hub metrics data for non-production environments for up to 10 days. After the configured date, PDC automatically stops collecting metrics for non-production environments. For example, if today is July 29 and you configure the end date as August 7, PDC stops collecting data on August 8.
To enable this function:
- Configure the PEGAAESREMOTE!AESSETTING/CAPTURERUNMETRICSTILL Dynamic System Settings (DSS) by providing an end date in the GMT format.
Reclassification of data-flows
If you have a manager role, you can reclassify data-flows. You can reassign data-flows from Data Processing to other categories based on a specific use-case to adjust your Customer Decision Hub metrics data in a way best suited for your business to help you bring maximum business value.
You can further configure the landing page view to present data that you currently need.
