## dlv trace

Compile and begin tracing program.

### Synopsis

Trace program execution.

The trace sub command will set a tracepoint on every function matching the
provided regular expression and output information when tracepoint is hit.  This
is useful if you do not want to begin an entire debug session, but merely want
to know what functions your process is executing.

The output of the trace sub command is printed to stderr, so if you would like to
only see the output of the trace operations you can redirect stdout.

```
dlv trace [package] regexp [flags]
```

### Options

```
      --ebpf               Trace using eBPF (experimental).
  -e, --exec string        Binary file to exec and trace.
      --follow-calls int   Trace all children of the function to the required depth. Trace also supports defer functions and cases where functions are dynamically returned and passed as parameters.
  -h, --help               help for trace
      --output string      Output path for the binary.
  -p, --pid int            Pid to attach to.
  -s, --stack int          Show stack trace with given depth. (Ignored with --ebpf)
  -t, --test               Trace a test binary.
      --timestamp          Show timestamp in the output
  -v, --verbose int        Parameter verbosity: 0=values, 1=types, 2=inline, 3=expanded, 4=full (default 0)
```

### Options inherited from parent commands

```
      --backend string         Backend selection (see 'dlv help backend'). (default "default")
      --build-flags string     Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"
      --check-go-version       Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve. (default true)
      --disable-aslr           Disables address space randomization
      --log                    Enable debugging server logging.
      --log-dest string        Writes logs to the specified file or file descriptor (see 'dlv help log').
      --log-output string      Comma separated list of components that should produce debug output (see 'dlv help log')
