STRUCT DIM_SAMPLE(9)

💖 struct dim_sample(9) 💖

okay bestie, welcome to the manual page for struct dim_sample — literally the structure for DIM sample data. it's the little messenger that carries info back and forth between DIM and its consumer, and honestly? it's giving middle-child energy but it's iconic. 🫶

this is from the Kernel API Manual, so yeah, we're in kernel land. no cap.

✨ SYNOPSIS ✨

struct dim_sample {
    ktime_t time;
    u32 pkt_ctr;
    u32 byte_ctr;
    u16 event_ctr;
    u32 comp_ctr;
 };

look at her. five fields, all business, zero fluff. 💅

🎀 Members 🎀

so here's the breakdown of every single member, and yes we're doing all of them:

• time — the sample timestamp. when it happened, periodt.
• pkt_ctr — the number of packets. counting them like a girlboss.
• byte_ctr — the number of bytes. more bytes, more vibes.
• event_ctr — the number of events. yes, we're tracking those too.
• comp_ctr — the current completion counter. she's currently completing, your honor.
