bcc-bpflist - Man Page
Display processes currently using BPF programs and maps.
Synopsis
bpflist [-v]
Description
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 output 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.
Requirements
bcc, debugfs
Options
-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.
Examples
- Display processes currently using BPF programs:
# bpflist
- Also count kprobes and uprobes:
# bpflist -v
Fields
- 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.
