Built-in Configuration

Create a span surrounding all calls to the annotated function by adding a //dd:span directive on the function declaration. The default operation (span) name is the name of the function, but this can be overridden by specifying a span.name argument:

//dd:span span.name:custom-operation-name other:tag
func myFunction() {
  // The default operation name would have been "myFunction"
}

Function literal expressions don’t have a function name, and their default operation name is the value of the very first directive argument (if there is one). If there are no directive arguments, the operation name will remain blank.

//dd:span other:tag span.name:custom-operation-name
myOp := func() {
  // The default operation name would have been "tag"
}

Flip a boolean to true if Orchestrion is enabled.

Protection from Local File Inclusion (LFI) Attacks

All known functions that open files are susceptible to Local File Inclusion (LFI) attacks. This aspect protects against LFI attacks by wrapping the os.OpenFile function with a security operation that will block the operation if it is deemed unsafe.

Instrumenting only the os.OpenFile function is sufficient to protect against LFI attacks, as all other functions in the os package that open files ultimately call os.OpenFile (as of Go 1.23).

Operations that interact with Go’s runtime system.
