This interface is used to define a strategy for instrumenting methods of
classes which are decorated with the [Instrument](/current/core/reference/typescript-api/telemetry/instrument#instrument) decorator.

```ts title="Signature"
interface InstrumentationStrategy extends InjectableStrategy {
    wrapMethod(args: WrappedMethodArgs): any;
}
```

* Extends: [`InjectableStrategy`](/current/core/reference/typescript-api/common/injectable-strategy#injectablestrategy)

<div className="members-wrapper">

### wrapMethod

\<MemberInfo kind="method" type={`(args: <a href='/current/core/reference/typescript-api/telemetry/wrapped-method-args#wrappedmethodargs'>WrappedMethodArgs</a>) => any`}   />

When a method of an instrumented class is called, it will be wrapped (by means of
a Proxy) and this method will be called. The `applyOriginalFunction` function
will apply the original method and return the result.
