+You can use the following types of interfaces to monitor the TiDB cluster status:
 
-- [The state interface](#running-status): this interface uses the HTTP interface to get the component information.
-- [Storage information](#storage-information): this interface uses the HTTP interface to get the storage information of data tables.
+- [The status interface](#use-the-status-interface): this interface uses the HTTP interface to get the component information. Using this interface, you can get the [running status](#running-status) of the current TiDB server and the [storage information](#storage-information) of a table.
 - [The metrics interface](#use-the-metrics-interface): this interface uses Prometheus to record the detailed information of the various operations in components and views these metrics using Grafana.

-The state interface monitors the basic information of a specific component in the TiDB cluster. It can also act as the monitor interface for Keepalive messages. In addition, the state interface for the Placement Driver (PD) can get the details of the entire TiKV cluster.
