NAME

bps - List all BPF programs. 'ps' for BPF programs.

SYNOPSIS

bps [bpf-prog-id]

DESCRIPTION

bps lists all BPF programs loaded into the kernel. It is similar to the ps command but for the BPF programs. Each loaded bpf program is identified by an unique integer (i.e. bpf-prog-id or simply BID). If a bpf-prog-id is specified, the maps used by bpf-prog-id will also be listed.

EXAMPLES

List all BPF programs loaded into the kernel: bps Show the details and maps of BID 6: bps 6

BPF PROGRAM FIELDS

BID BPF program ID. It ends with '-' if it is not jitted. TYPE The type of a BPF program. e.g. kprobe, tracepoint, xdp...etc. UID The user ID that loaded the BPF program. #MAPS Total number of maps used by a BPF program. LoadTime When was the BPF program loaded? NAME The name of a BPF program. The user space library (like bcc ) usually uses the C function name of the original BPF's source code as the program name. It could be empty if the user space did not provide a name.

BPF MAP FIELDS

MID BPF map ID. TYPE The type of a BPF map. e.g. hash, array, stack trace...etc. FLAGS The flags used to create the BP map. KeySz The key size of a BPF map. ValueSz The value size of a BPF map. MaxEnts The maximum number of entries of a map. NAME The name of a BPF map. The user space library (like bcc ) usually uses the C vari‐ able name of the BPF map as its name. It could be empty if the user space did not provide a name.
