You can request eBPF monitoring by including "ebpf_programs" in your diagnostic response:

"filters": {"comm": "process_name"},
|
||||
"description": "Monitor file open operations"

}

]

|

|

Available eBPF program types:
|

- tracepoint: Monitor kernel tracepoints (e.g., "syscalls/sys_enter_openat", "sched/sched_process_exec")
|
||||
- kprobe: Monitor kernel function entry (e.g., "tcp_connect", "vfs_read")
|
||||
- kretprobe: Monitor kernel function return (e.g., "tcp_connect", "vfs_write")
|
||||
|
||||
Common targets:
|
||||
- syscalls/sys_enter_openat (file operations)
|
||||
- syscalls/sys_enter_execve (process execution)
|
||||
- tcp_connect, tcp_sendmsg (network activity)
