Chapter 8: Exploring the Admin User Interface
In Chapter 7, Schema Creation and Management, we learned about various SQL syntaxes and how to manage schema changes. In this chapter, we will learn what information is available in the admin user interface (UI) for monitoring a CockroachDB cluster.

The admin UI mainly provides information about the metrics, database and table definitions, sessions, transactions, network latencies, active jobs, and advanced debugging information. Network latency is important when debugging query latencies, just to rule out slowness due to the network. Also, if you have multi-cloud or hybrid cloud CockroachDB clusters, it is important to understand the latencies across various cloud providers. Schema changes, backup and restore jobs, data imports, and changefeed are covered on the Jobs tab.
