Ask HN: Good examples of management dashboards?

Was talking it over with some coworkers, and we couldn't come to an agreement over any examples of dashboard that were well thought out and succinctly presented all the information it needed to, without overwhelming the user.

I had suggested digitalocean's dashboard was elegant and concise,but a few other developers thought it was too simple, they preferred something more like nasa's open MCT.

Obviously it is heavily dependent on what information is being presented and what the dashboard is being used for, but I am interested in hearing what examples of management dashboards you have come across.
