We should probably also remove these fields (ConnectionCount, RxBytes, TxBytes) from thet.Logf as well as they're not relevant to this test. If we need to introspect in more detail, a debugger is probably a better option.

I disagree --- although we shouldn't be asserting their values, it can be useful to see them in logs so you can tell the difference between a test that misclassifies the VSCode session from one where we fail to connect at all, or fail to get any meaningful stats.
The debugger is great, but relatively useless for diagnosing rare-ish flakes.

Fixescoder/internal#564
The test is asserting too much, including stats guages that are not directly related to the thing we are trying to test: ConnectionCount, RxBytes, and TxBytes. I think the author assumed that these are counts that only go up, but they are guages and eventually zero back out, so there are race condtions where not all of them are non-zero at the same time.
