Heuristics is disabled or not available in APM 10.5

Products

• INTROSCOPE

Issue/Introduction

After upgrading from CA APM 9.7 to CA APM 10.5, we observed that the Heuristics statistic is in disabled stated.

We also noticed that the following configuration in the 9.7 IntroscopeEnterpriseManager.properties file, is no longer available in the 10.5 IntroscopeEnterpriseManager.properties file:

 

#######################
# Application Heuristics
#
# Setting this to false improves the performance of the EM but disables the EM's assessment of JVM, application,

# and backend health
#
# ================
introscope.enterprisemanager.application.overview.baselines=true

 

Is this an expected behavior, or is there any additional configuration required to enable Heuristics in APM 10.5?

Environment

CA Application Performance Management 10.x

Resolution

Heuristics metrics functionality has been completely removed in 10.X. All the Management Modules that depends on heuristics metrics functionality are no longer valid and should not be used in 10.X environment.

We have introduce a new functionality in APM 10.X which is called Differential Analysis that replaces the heuristics metrics functionality, providing better way to monitor application stability through historical data analysis.

 

Please refer to following topics in the user guide for more details:
