The participant doesn't need to instrument the writers in order to notify this callback. Please remove from the mask in:

Fast-DDS/src/cpp/statistics/rtps/StatisticsBase.cpp

Line 138 in 8def391

constexpr uint32_t writers_maks = HISTORY2HISTORY_LATENCY \

Add the new callback to the comments in:

Fast-DDS/test/unittest/statistics/rtps/RTPSStatisticsTests.cpp

Lines 519 to 527 in 8def391

	/*
	* This test checks RTPSParticipant, RTPSWriter and RTPSReader statistics module related APIs.
	* - RTPS_SENT callbacks are performed
	* - DATA_COUNT callbacks are performed for DATA submessages
	* - RESENT_DATAS callbacks are performed for DATA submessages demanded by the readers
	* - ACKNACK_COUNT callbacks are performed
	* - HEARBEAT_COUNT callbacks are performed
	* - SAMPLE_DATAS callbacks are performed

	/*
