A more comprehensive answer about how managers are assessed at Google (via Google's project Oxygen):

- Is a good coach

- Empowers the team and does not micromanage

- Expresses interest in and concern for team members’ success and personal well-being

- Is productive and results-oriented

- Is a good communicator—listens and shares information

- Helps with career development

- Has a clear vision and strategy for the team

- Has key technical skills that help him or her advise the team

Your manager should at least be striving to excel at those. Different managers will have different strengths, but the most important thing IMHO is that they care about their team and want to do better.
