Edge Types

Causal edges explain why one event is related to another.

Edge	Meaning
SEQUENTIAL	Events occurred sequentially in the same execution context.
TCP_RTT	TCP send and receive activity contributed to request timing.
DISK_TO_SYSCALL	Storage I/O delayed a syscall.
MEMORY_PRESSURE	Page faults or memory pressure delayed work.
CPU_CONTENTION	Scheduler behavior delayed a process or thread.
SCHED_DELAY	A process was ready but waited for CPU.
TRACE_CONTEXT	Kernel event belongs to a trace or span.

Edges include latency and evidence fields so engineers can inspect why kprobe created the relationship.
