Prediction Studio notifications
Valid from Pega Version 8.3
Prediction Studio now displays notifications when adaptive or predictive models encounter problems. For example, if the performance of a model decreases suddenly, a notification appears, which you can use to immediately investigate the cause of the problem.
For more information, see Accessing Prediction Studio notifications and Prediction Studio notification types.
REST API for monitoring DSM services
Valid from Pega Version 8.3
Decision Strategy Manager (DSM) now provides a REST API that you can use to monitor DSM services without having to access Pega Platform™. By integrating your daily monitoring tools with the management REST API, you can retrieve a list of DSM nodes, check the status of these nodes, and view details of a service from all nodes in the cluster.
For more information, see Getting started with Pega API for Pega Platform.
Unable to create text analytics models when Java 2 Security is enabled
Valid from Pega Version 7.3
Security exceptions that prevent you from creating text analytics models are caused by the Java 2 Security feature that is enabled at the JVM level. This feature denies access to the text analytics resources that are required for text parsing functions.
Creating a text analytics model results in a failure because of a number of security-related exceptions, for example:
java.security.AccessControlException: Access denied ("java.lang.RuntimePermission""createSecurityManager")
The suggested approach for avoiding this problem is to use the text analytics models that are provided by default, for example, pySentimentModels, pyTelecomTaxonomy, and so on.
For more information, see Text Analyzer.
Improved diagnostics and logging for Decision Data Store nodes
Valid from Pega Version 7.3
On the Decision Data Store tab, you can view additional metrics from the Decision Data Store nodes that help with diagnosing Cassandra database problems. You can also set the logging level to control interactions from and to Decision Data Store nodes.
For more information, see Decision Data Service node status information and Configuring the Decision Data Store service.
Tracing Cassandra queries in a Decision Data Store data set
Valid from Pega Version 7.3
You can now enable the Trace option for every operation in the Decision Data Store data set to collect information about how the Decision Data Store queries are executed in Cassandra. You can view this information in the clipboard and use it to troubleshoot and optimize performance of the Decision Data Store data sets and Decision Data Store nodes. All the queries and related events are collected on the DDSTraces page on the same Pega thread.
For more information, see Tracing Decision Data Store operations.
