perf_stat__..._metricgroup(9)

🎀 NAME 🎀

perf_stat__print_shadow_stats_metricgroup — the little function that prints out the metrics associated with the evsel 💖

okay so bestie, here's the vibe check on how the printing actually goes down:

• In the non-default case, all the metrics associated with the evsel get printed. All of them. The whole buffet. 🍓
• In the default mode, only the metrics from the same metricgroup get printed — plus the name of the metricgroup itself. That's it, that's the whole output. modest. lowkey humble. 🎀
• Wanna print the metrics from the next metricgroup (if there even is one)? 👀 Then invoke the function with the corresponding metric_expr. that's the move, no cap.

✨ SYNOPSIS ✨

void * perf_stat__print_shadow_stats_metricgroup (struct
       perf_stat_config *config , struct evsel *evsel , int aggr_idx , int *num
       , void *from , struct perf_stat_output_ctx *out );

literally just vibes and six arguments, slay 💅

💅 ARGUMENTS 💅

okay so the manpage is being super mysterious about these, and honestly? iconic of it. every single one is marked -- undescribed -- in the source, so I'm not gonna sit here and invent lore that isn't there 🙈

• config — -- undescribed -- 😭
• evsel — -- undescribed -- 😭
• aggr_idx — -- undescribed -- 😭
• num — -- undescribed -- 😭
• from — -- undescribed -- 😭
• out — -- undescribed -- 😭

bestie I'm as curious as you are, but the docs said "no thoughts, head empty" and I respect the boundary 🫶. the names of the parameters are right there though — go read the code for the real tea, iykyk 💀
