Compile with STATISTICS=ON
My first guess here is that your fastrtps
version is not compiled with CMake option -DFASTDDS_STATISTICS=ON
.
Default ROS2 Humble does not compile with statistics, so no statistical data will be published.
Be aware that CMake option -DFASTDDS_STATISTICS=ON
must be set to fastrtps
compilation, not to fastdds_monitor
compilation. So the ROS2 source code must be rebuilt in order to do so.
Check our ROS2 distribution that has the statistics available by default, and have some new features and applications that are not available in ROS2: https://docs.vulcanexus.org/en/latest/rst/tutorials/tools/fastdds_monitor/fastdds_monitor.html
Memory restriction
There is another known issue related with such scenario. Check this documentation in case the previous advice does not work: https://fast-dds.docs.eprosima.com/en/latest/fastdds/statistics/dds_layer/troubleshooting.html#monitoring-application-is-not-receiving-any-statistic-data
