<<extension>> Configures the distribution of event metrics.
Event metrics are provided to RTI Monitoring Library 2.0 when they change.
For example, if the liveliness of a dds::pub::DataWriter is lost, a matching dds::sub::DataReader will push the new value of dds::core::status::LivelinessChangedStatus to RTI Monitoring Library 2.0 so that the liveliness status change can be distributed.
There are three kinds of event metrics:
The event metrics that will be distributed for an observable resource can be configured with rti::core::MonitoringTelemetryData::metrics.

Creates an instance with the default settings.
MonitoringEventDistributionSettings & rti::core::MonitoringEventDistributionSettings::concurrency_level | ( | uint32_t | the_concurrency_level | ) |
Defines how concurrent the push of event metrics to RTI Monitoring Library 2.0 is.
With a concurrency_level of one, all the event metrics pushed to RTI Monitoring Library 2.0 will be stored in a single queue protected by a single mutex.
With a concurrency_level of 'n', RTI Monitoring Library 2.0 will create 'n' queues for event metrics, each queue protected by its own mutex. Each resource (e.g, a dds::sub::DataReader) will be associated with one of the queues when the resource is registered with RTI Monitoring Library 2.0. Therefore, all the event metrics for a single resource always go to the same queue.
The event metrics for two resources associated with different event queues can be pushed in parallel. This is why a higher concurrency_level provides more concurrency.
The event metrics added to the event queues are processed by a single thread configured using rti::core::MonitoringEventDistributionSettings::thread.
[default] 5
[range] [1, 100]
uint32_t rti::core::MonitoringEventDistributionSettings::concurrency_level | ( | ) | const |
Getter (see setter with the same name).
MonitoringEventDistributionSettings & rti::core::MonitoringEventDistributionSettings::datawriter_qos_profile_name | ( | const rti::core::optional_value< std::string > & | the_datawriter_qos_profile_name | ) |
Sets The fully qualified name of the profile used to configure the dds::pub::DataWriter that distributes event metrics.
the_datawriter_qos_profile_name | An optional string. An unset value indicates that the RTI Monitoring Library 2.0 uses rti::core::builtin_profiles::qos_lib::generic_monitoring2(). |
[default] Unset
The dds::pub::DataWriter Topic is MONITORING_EVENT_TOPIC_NAME.
If null (the default value), then RTI Monitoring Library 2.0 uses rti::core::builtin_profiles::qos_lib::generic_monitoring2().
[default] null
MonitoringEventDistributionSettings & rti::core::MonitoringEventDistributionSettings::datawriter_qos_profile_name | ( | const char * | the_datawriter_qos_profile_name | ) |
Sets The fully qualified name of the profile used to configure the dds::pub::DataWriter that distributes event metrics.
the_datawriter_qos_profile_name | The profile name. Cannot be NULL. |
The dds::pub::DataWriter Topic is MONITORING_EVENT_TOPIC_NAME.
If null (the default value), then RTI Monitoring Library 2.0 uses rti::core::builtin_profiles::qos_lib::generic_monitoring2().
[default] null
rti::core::optional_value< std::string > rti::core::MonitoringEventDistributionSettings::datawriter_qos_profile_name | ( | ) | const |
Getter (see setter with the same name).
MonitoringEventDistributionSettings & rti::core::MonitoringEventDistributionSettings::thread | ( | const rti::core::ThreadSettings & | the_thread | ) |
The settings of the event metric thread.
The event metric thread periodically publishes the event metrics pushed into RTI Monitoring Library 2.0 event metric queues after they change their values.
The thread runs at the period configured using rti::core::MonitoringEventDistributionSettings::publication_period.
[default] DDS_THREAD_SETTINGS_DEFAULT
const rti::core::ThreadSettings & rti::core::MonitoringEventDistributionSettings::thread | ( | ) | const |
Getter (see setter with the same name).
rti::core::ThreadSettings & rti::core::MonitoringEventDistributionSettings::thread | ( | ) |
Getter (see setter with the same name).
MonitoringEventDistributionSettings & rti::core::MonitoringEventDistributionSettings::publication_period | ( | const dds::core::Duration & | the_publication_period | ) |
Period at which the event metric thread publishes the event metrics that have changed since the last time they were published.
With a period of 0 seconds, changes to event metrics will be published immediately after they are pushed into RTI Monitoring Library 2.0.
[default] 1 second
dds::core::Duration rti::core::MonitoringEventDistributionSettings::publication_period | ( | ) | const |
