Fields

skip_idle: bool

stream_mode: u8

frequency: u64

kprobe: Option<String>

uprobe: Option<UProbeConfig>

Legacy single-target uprobe config (backward compat).

smart_uprobe: Option<SmartUProbeConfig>

New smart uprobe config with multi-attach support.

tracepoint: Option<String>

raw_tracepoint: Option<String>

Raw tracepoint name for syscall raw_tp (e.g., “sys_enter”). Uses collect_trace_raw_syscall which reads pt_regs from args[0].

raw_tracepoint_task_regs: Option<String>

Raw tracepoint name for generic raw_tp with task pt_regs (e.g., “sched_switch”). Uses bpf_get_current_task_btf() + bpf_task_pt_regs() for full FP/DWARF unwinding. Requires kernel >= 5.15; falls back to raw_tracepoint_generic on older kernels.

raw_tracepoint_generic: Option<String>

Raw tracepoint name for generic raw_tp (e.g., “sched_switch”). Uses collect_trace_raw_tp_generic which relies on bpf_get_stackid only.

target_syscall_nr: i64

Target syscall number for raw tracepoint filtering (-1 = all).

pid: Option<u32>

cpu: Option<u32>

self_profile: bool

dwarf: bool
