bpftrace

High-level tracing language for Linux eBPF. More information: https://github.com/bpftrace/bpftrace/blob/master/man/adoc/bpftrace.adoc.

• 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}}'

• Display version:

bpftrace {{[-V|--version]}}
