bpflist(8) System Manager's Manual bpflist(8)
bpflist - Display processes currently using BPF programs and maps.
This tool displays processes currently using BPF programs and maps, and optionally also
kprobes and uprobes on the system. This is useful to understand which BPF programs are
loaded on the system.
Currently, for lack of a better alternative, this tool pipes into 'ls' and parses its out‐
put to snoop for BPF file descriptors in all running processes. In the future, when BPF
accounting is provided by the kernel, this tool should use these accounting features.
Only the root user can use this tool, because it accesses debugfs.
-h Print usage message.
-v Count kprobes and uprobes as well as BPF programs. Repeating verbose mode twice
also prints the kprobe and uprobe definitions in addition to counting them.
Display processes currently using BPF programs:
Also count kprobes and uprobes:
# bpflist -v
PID Process ID.
COMM Process comm.
TYPE The type of the data displayed: BPF program, BPF map, kprobe, or uprobe.
COUNT The number of items of this type that belong to the specified process.
This is from bcc.
Also look in the bcc distribution for a companion _examples.txt file containing example
usage, output, and commentary for this tool.
