3.7.1. Verbosity

Increase the verbosity from the command line to view information about which Topics have been discovered. For example, running with -verbosity 4 shows that Recording Service has discovered a Square Topic.

[/recording_services/RecorderService/domain_participants/Participant0|STREAM_DISCOVERED name=Triangle] type_name=ShapeType
[/recording_services/RecorderService/domain_participants/Participant0|STREAM_DISCOVERED name=Triangle|../../sessions/DefaultSession/topics/RecordAll@Triangle|CREATE]
[/recording_services/RecorderService/domain_participants/Participant0|STREAM_DISCOVERED name=Triangle|../../sessions/DefaultSession/topics/RecordAll@Triangle|ENABLE]
[/recording_services/RecorderService/sessions/DefaultSession/topics/RecordAll@Triangle|START]
[/recording_services/RecorderService/sessions/DefaultSession/topics/RecordAll@Triangle|RUN]

At verbosity level 4, it is also possible to see incompatible QoS.

[/recording_services/RecorderService/sessions/DefaultSession/topics/RecordAll@Triangle|RUN]
