System design round at LinkedIn. It focuses on both HLD and LLd.
Duration - 60 mins.

question - Design a metric collection and querying system.

The system will both collect metrics from a large fleet of machines,

and retrieve them over a requested period of time to be shown in an external visualization system.

You can assume that a metric is represented by the [timestamp, node, metric, value] tuple.

Awaiting for reply from the recruiter.
