Use Case

As a driver engineer
I want to add the new logger to the SRVPoller if NODE-4719 does not cover this case
So that any errors in server polling can be reported

Description

Since we removed the legacy logger in NODE-4817, the SRVPoller no longer has the capacity to report any errors.

Open questions

• Should we add an SrvPollerFailure event to allow users to programatically keep track of server discovery?
• Do other drivers worry about this type of failure?
• What logging component would this go under?

Acceptance Criteria

Implementation Requirements

• adds logging to the following methods
  • SrvPoller.failure
  • SrvPoller.schedule

• Reimplement parentDomainMismatch method

Testing Requirements

• Unit tests to ensure that we capture a log message on any SrvPoller errors
