Pega Predictive Diagnostic Cloud™ (PDC) is a Software as a Service (SaaS) tool that runs on Pega Cloud®. PDC actively gathers, monitors, and analyzes real-time performance and health indicators from all active Pega Platform™ applications.
Pega Platform sends known and safe content to PDC using only the clipboard parameter data that is required for analysis. The data is sent asynchronously to minimize any performance impact on the monitored Pega implementation. Data with identifying information (for example, case data) is not sent due to privacy concerns, and PDC does not request information from the monitored application.
Pega Platform gathers the following data for PDC:
PDC analyzes and aggregates the data generated from Pega Platform applications to produce trending dashboards. The trending dashboards provide a graphical representation of daily average response usage, Interaction volume, and user sessions counts. The presentation of data in trend graphs helps to monitor, isolate and identify and anticipate issues by presenting behavior over time. PDC empowers business stakeholders and IT administrators to take preventative action by predicting potential system performance and business logic issues and providing remediation suggestions.
PDC allows you to monitor several on-premise and cloud-based Pega Platform applications. Systems that run on Pega Cloud already have PDC integration. Pega Cloud provides a URL from which you access PDC.

Pega Predictive Diagnostic Cloud (PDC) helps you identify areas that you need to work on to improve your system's performance. Use Improvement Plan to view a summary of issues that affect the performance of your monitored system. Use Event Viewer to conduct an in-depth investigation
The following articles guide you through common use cases for identifying issues in your system:
Resolve common performance issues and find the root cause by using the Pega Predictive Diagnostic Cloud (PDC) problem-solving tools. With Event Viewer, you can access diagnostic data from all the nodes in your system.
To start resolving a performance or stability issue, consider the following actions:
For example, if you know when your system failed, you can verify the alerts and exceptions that were generated at that time. By analyzing these events, you can determine the problem that caused the selected system to fail.
For example, narrow the possible sources of diminished performance to a single user, node, or application.

Pega Predictive Diagnostic Cloud (PDC) provides numerous measurements of your system that you can receive as messages to help you address any issues that might occur. With these messages, called notifications, you can immediately react to important issues in your system or counteract potential stability problems.
To receive only the measurements that are relevant and useful for you, determine what data you need to receive on a regular basis and what information is useful only when you troubleshoot a specific issue. The type and frequency of notifications that can help you the most depend on your user role.
Notifications are available only for events that are important and require immediate attention or additional action.
You need to create separate notifications for each of your systems that PDC monitors.
Each notification informs you about an issue in your system, such as unresponsive components, exceeded time thresholds, or low resources. PDC can detect hundreds of thousands of events, and you cannot react to each event individually. Therefore, subscribe only to notifications about the events that are most relevant to your system. Because every application uses different components in different ways, you choose notifications manually.
After you use PDC for some time, you can revise the subscriptions to stay informed about the events that are most relevant to your system and application.
During subscription, operators can add more than one account to each notification.
By default, PDC sends notifications by email. However you can configure PDC to send individual notifications using SMS, notification API, or to ServiceNow.
For more information about configuring notifications, see Managing notifications in Pega Predictive Diagnostic Cloud.
You can further customize how you receive notifications using the notification API feature in PDC. With the notification API, your system can receive notifications directly from the API.
PDC provides notifications for Stability category alerts and other alerts that are significant when they occur once. When such an alert requires your immediate attention, PDC provides an #urgent alert. PDC does not provide notifications for alerts that are only significant when they occur in large numbers, such as most Database, Connector, and Performance category alerts. Runtime Guardrail and Decisioning category alerts provide recommendations and help you to implement best practices. PDC does not provide notifications for these alerts. Instead, log in to PDC on regular basis to monitor and improve your applications.
On the Slow Interactions landing page, you can find a list of all of the affected, client-facing endpoints in all of your applications. The page shows all cases that are related to the PEGA0001, PEGA0011, and PEGA0069 alerts. You can configure the customizable data grid according to your preferences. Performance alerts usually matter when an issue occurs in bulk rather than once. For example, one individual PEGA0001 alert might not be significant, but a large number of PEGA0001 messages might indicate an underlying problem, such as a server issue that causes a significant slowdown.
