# bpftrace
|
|
|
|
> High-level tracing language for Linux eBPF.
|
|
> More information: <https://github.com/iovisor/bpftrace>.
|
|
|
|
- Display bpftrace version:
|
|
|
|
`bpftrace -V`
|
|
|
|
- List all available probes:
|
|
|
|
`sudo bpftrace -l`
|
|
|
|
- Run a one-liner program (e.g. syscall count by program):
|
|
|
|
`sudo bpftrace -e '{{tracepoint:raw_syscalls:sys_enter { @[comm] = count(); }}}'`
|
|
|
|
- Run a program from a file:
|
|
|
|
`sudo bpftrace {{path/to/file}}`
|
|
|
|
- Trace a program by PID:
|
|
|
|
`sudo bpftrace -e '{{tracepoint:raw_syscalls:sys_enter /pid == 123/ { @[comm] = count(); }}}'`
|
|
|
|
- Do a dry run and display the output in eBPF format:
|
|
|
|
`sudo bpftrace -d -e '{{one_line_program}}'`
