RTI Observability Library.

RTI Observability Library is one component of the RTI Connext Observability Framework which allows collecting and distributing telemetry data (metrics and logs) associated with the observable resources created by an RTI Connext application.

In this release, the only Observable resources are the following entities: com.rti.dds.publication.DataWriter, com.rti.dds.subscription.DataReader, com.rti.dds.publication.Publisher, com.rti.dds.subscription.Subscriber, com.rti.dds.domain.DomainParticipant, com.rti.dds.topic.Topic and Application (a process running RTI Connext).

The library also accepts remote commands to change the set of distributed telemetry data at run-time.

The data distributed by the RTI Observability Library is sent to an RTI Observability Collector Service instance, which forwards the data to other RTI Observability Collector Service instances or stores the data in third-party observability backends such as Prometheus or Grafana Loki.

The RTI Observability Library is a separate library (rtimonitoring2), and applications can use it in three different modes:

Dynamically loaded: This is the default mode, and it requires that the rtimonitoring2 shared library is in the library search path.
Dynamic linking: The application is linked with the rtimonitoring2 shared library.
Static linking: The application is linked with the rtimonitoring2 static library.

Dynamic and static linking are only supported in C and C++ applications.

To enable use of the RTI Observability Library and configure its behavior, use the com.rti.dds.infrastructure.MonitoringQosPolicy QoS policy on the com.rti.dds.domain.DomainParticipantFactory. This QoS policy can be configured programmatically or via XML.
