# Cluster status

The HTTP interface exposed by TiDB is http://host:port/status, and the default port number is 10080 (can be set through the-- status parameter)

You can access this interface to get the status of the current TiDB Server and determine whether it is alive or not. The returned result is in Json format:

[root@node1 ~] # curl 192.168.174.134:10080/status {"connections": 0, "version": "5.7.1-TiDB-1.0", "git_hash": "d6ec37bb4219e95babce41bd0400d04d84b1fb88"}

PD Server

PD API address: http://${host}:${port}/pd/api/v1/${api_name}

Port defaults to 2379. For more information about all kinds of api_name, see
