Possible incorrect type in HostMetrics

[rowanmanning]

What version of OpenTelemetry are you using?

@opentelemetry/host-metrics@0.35.2

What version of Node are you using?

20.10.0

What did you do?

In an app with TypeScript type checking, I'm doing the following:

const { HostMetrics } = require('@opentelemetry/host-metrics');
const hostMetrics = new HostMetrics({});

What did you expect to see?

I expected to see no type errors as the name option of HostMetrics is defaulted in the base class here.

What did you see instead?

I get a type error:

Argument of type '{}' is not assignable to parameter of type 'MetricsCollectorConfig'.
  Property 'name' is missing in type '{}' but required in type 'MetricsCollectorConfig'.

This is because the MetricsCollectorConfig type does not specify that name is optional (see here).

Additional context

I'd be happy with any of the following:

• Adjust the types to indicate that name is optional. If so, then should the entire config object be optional too?
• Adjust the code so that name isn't defaulted, possibly throwing an error if name is not configured
• Do nothing and close this issue so at least somebody knows the current behaviour is intentional if that's the case
