Public bug reported:

When the resource tracker tries to collect metric data, if something
goes wrong, the stack trace isn't shown and it masks the underlying
problem and makes debug difficult.

For example, here's the message you see...

[req-141a8c26-fa98-470d-accb-97b15bf98d70 - - - - -] Cannot get the
metrics from...

...and no stack trace.
