Analizar el rendimiento de la aplicación con PDC

Pega Predictive Diagnostic Cloud (PDC) es una herramienta de software como un servicio (SaaS) que se ejecuta en los servicios de Pega Cloud®. PDC recopila, supervisa y analiza activamente los indicadores de estado y rendimiento en tiempo real de todas las aplicaciones activas de Pega Platform™.

Pega Platform envía contenido seguro y conocido a PDC mediante solo los datos del parámetro de portapapeles que se requieren para el análisis. Los datos se envían de manera asíncrona para minimizar cualquier impacto de rendimiento en la implementación supervisada de Pega Platform. Por motivos de resguardo de la privacidad, no se envían datos con información de identificación (por ejemplo, datos del caso), y PDC no solicita información desde la aplicación supervisada.

Pega Platform recopila los siguientes datos para PDC:

  • Alertas: Identifica el tipo de alerta y los metadatos que se capturan en una interacción.
  • Página de parámetros: describe los parámetros de la página de parámetros actual, incluida información contextual importante sobre las funciones que se ejecutan en la aplicación supervisada. Todos los parámetros restantes se filtran y se excluyen.
  • Alertas de la base de datos: Detalla la consulta de la base de datos, sin incluir valores de datos del negocio.
  • Excepciones: Contiene algunos datos contextuales que conforman un subconjunto de los campos que se envían para las alertas.
  • Estadísticas de rendimiento: Incluye estadísticas del tiempo de respuesta promedio y un recuento de usuario único. PDC utiliza estas estadísticas para identificar el rendimiento general y las tendencias de rendimiento de las aplicaciones supervisadas.
  • Índices de base de datos: Incluye información sobre el índice de la base de datos. PDC utiliza la información sobre el índice de la base de datos para generar recomendaciones a fin de mejorar el rendimiento de la consulta.

Dashboards de PDC

PDC analiza e incorpora los datos generados en las aplicaciones de Pega Platform para producir dashboards de tendencias. Los dashboards de tendencias proporcionan una representación gráfica del promedio por día del uso de respuesta, el volumen de interacción y los recuentos de sesiones del usuario. La presentación de datos en gráficos de tendencia ayuda a supervisar, aislar e identificar y anticipar problemas gracias al comportamiento en el tiempo. PDC les otorga a las partes interesadas del negocio y administradores de TI las herramientas necesarias para tomar las acciones preventivas prediciendo el potencial rendimiento del sistema y los problemas en la lógica del negocio y proporcionando las sugerencias de remediación.

PDC analiza y agrupa datos de alertas, uso y estado de recursos, y pulsos de estado del sistema para generar gráficos de tendencia, como se muestra en la siguiente imagen.

Overview of PDC

PDC le permite supervisar varias aplicaciones de Pega Platform locales y basadas en la nube. Los sistemas que se ejecutan en Pega Cloud ya tienen una integración de PDC, y Pega Cloud proporciona una URL mediante la cual usted puede acceder a PDC.

Issue Identification and research with Pega Predictive Diagnostic Cloud

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:

Resolving issues in your system with Pega Predictive Diagnostic Cloud

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:

  • In Improvement Plan, open a case, and then follow the recommended next steps.
  • In Event Viewer, view the log data from the past 14 days, and then analyze the issues that occurred during that time.

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.

  • To quickly find the root cause of an issue, organize diagnostic data with customizable sets of filters.

For example, narrow the possible sources of diminished performance to a single user, node, or application.

For more information about event types in PDC, see Cases in Pega Predictive Diagnostic Cloud.

Notifications in Pega Predictive Diagnostic Cloud

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.

PDC supports the following types of notifications:
Daily digest notifications
Periodic summaries of issues that PDC detects in your system. These notifications focus on specific categories, for example, Improvement Plan TOP 5 Web events or Improvement Plan TOP 5 Overall issues. You can configure PDC to send daily digests in any range from daily to weekly notifications. This type of notifications is most useful for manager roles for a general overview of your system health.
Event-based notifications
Messages that PDC sends when a specific number of the same events occur during a certain timespan. You can configure the event threshold and the time interval for each notification. This type of notifications is most useful for operations team members who can use them to swiftly react to stability and performance issues.

You need to create separate notifications for each of your systems that PDC monitors.

Choosing daily digest notifications

As part of system governance, subscribers receive the following scheduled digests to keep them up to date about the status of a monitored system:
Cases Summary
A summary of the active cases in PDC for the selected systems. Cases require at least one alert in the last 7 days to be considered active. The data is collected each day at 0:00 GMT. The report contains the active cases for a 7-day period, the new cases that were created in the last 24-hour period, and the number of unassigned cases.
To see the details of the new cases, see the New items daily report.
CDH Usage Summary
A summary of Pega Customer Decision Hub™ usage metrics with information on the month to date, the current day, the total usage, and the trend in usage data.
Event Summary
A summary of events that occurred over a 24-hour period on the selected systems.
Improvement Plan Top 5 Background
A report on up to the top five most urgent issues that affect background processing for each of the categories on the selected systems (Database, Connectors, General Performance, Stability, Runtime Guardrails, Custom Cases, and Decisioning). The report displays the amount of time the system spent processing background work and shows the percentage of time spent last week compared to the time spent this week.
Improvement Plan Top 5 Overall
A complete Improvement Plan for the selected system with up to the top five most urgent issues overall for each of the categories on the selected systems. The report displays the amount of time that the system spent processing web, service, and background work and shows the percentage of time spent last week compared to the time spent this week.
Improvement Plan Top 5 Service
A report on up to the top five most urgent issues that affect services for each of the categories on the selected systems. The report displays the amount of time that the system spent processing service requests and shows the percentage of time spent last week compared to the time spent this week.
Improvement Plan Top 5 Web
A report on up to the top five most urgent issues that affect the web for each of the categories on the selected systems. The report displays the amount of time the system spent processing web requests and shows the percentage of time spent last week compared to the time spent this week.
New items daily
A list of new issues that have been created in the last 24 hours.

Choosing event-based notifications

Note: To view all events for which PDC can send notifications, see List of notifications available in Pega Predictive Diagnostic Cloud.

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.

As a best practice, review the following notification types:
  • Focus on the events that can affect the stability of your system. These events are marked as Recommended.
  • Check the list for events that require urgent attention and subscribe to the events that apply to your system. These events are marked as Urgent.
  • Check the list for infrastructure events that help you to manage resources inside your system. These events are marked as Infrastructure resources.
  • Look at other notifications and subscribe to the types that are most relevant to your system.

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 by SMS, notification API, or to ServiceNow.

For more information about configuring notifications, see Managing notifications in Pega Predictive Diagnostic Cloud.

Notification API

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.

To connect your system to the notification API, the system must support the OAuth protocol and be able to relay notifications to end users. During configuration, PDC generates the following authentication data:
  • Endpoint URLs for token authorization
  • Client ID
  • Client secret
You then use this data to access the API. For more information, see Subscribing to Pega Predictive Diagnostic Cloud notifications by using a REST API.
