Description
The hosts table contains a row for each host used by clients to connect to the server, containing current and total connections.
The size is determined by the performance_schema_hosts_size system variable, which, if set to zero, will disable connection statistics in the hosts table.
It contains the following columns:
| Column | Description |
|---|---|
HOST | Host name used by the client to connect, NULL for internal threads or user sessions that failed to authenticate. |
CURRENT_CONNECTIONS | Current number of the host's connections. |
TOTAL_CONNECTIONS | Total number of the host's connections |
Example
SELECT * FROM hosts; +-----------+---------------------+-------------------+ | HOST | CURRENT_CONNECTIONS | TOTAL_CONNECTIONS | +-----------+---------------------+-------------------+ | localhost | 1 | 45 | | NULL | 20 | 23 | +-----------+---------------------+-------------------+
