The -M metric group parser threw away the events of earlier groups when multiple groups were specified. Fix this here by not overwriting the string incorrectly. Now this works correctly: % perf stat -M Summary,SMT --metric-only -a sleep 1 Performance counter stats for 'system wide': Instructions CPI CLKS CPU_Utilization GFLOPs SMT_2T_Utilization SMT_2T_Utilization Kernel_Utilization CoreIPC CORE_CLKS 900907376.0 2.7 2398954144.0 0.1 0.0 0.2 0.2 0.1 0.4 2080822855.5 while previously it would only show the SMT metrics.
