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 variable name of the BPF map as its name. It could be empty if the user space did not provide a name.
