6.15. Known Issues with RTI Monitoring Library 2.0
The following known issues occur in RTI Monitoring Library 2.0, not in RTI Monitoring Library. See MONITORING QosPolicy (DDS Extension) in the Connext Core Libraries User’s Manual for information on Monitoring Library 2.0.
6.15.1. Slow DDS Entity creation in large applications
Enabling Monitoring Library 2.0 can significantly slow down the creation of
new DDS entities in large applications with thousands of existing entities,
especially when the library is configured with a non-trivial
<resource_selection> expression in the <telemetry_data> section.
Non-trivial expressions are those that do not follow the simple forms:
//*//<resource_class>/*
More complex expressions introduce overhead during entity creation, affecting performance.
