NAME
SHOW_POOL_POOLS - sends back a list of pools handled by Pgpool-II.
SYNOPSIS
SHOW POOL_POOLS
DESCRIPTION
SHOW POOL_POOLS sends back a list of pools handled by Pgpool-II
It has 17 columns:
• pool_pid is the PID of the displayed Pgpool-II process.
• start_time is the timestamp of when this process was launched.
• If child_life_time is set not 0, the time before process restarting is displayed.
• client_connection_count counts the number of times this process has been used by clients.
• pool_id is the pool identifier (should be between 0 and max_pool - 1)
• backend_id is the backend identifier (should be between 0 and the number of configured backends minus
one)
• database is the database name for this process's pool id connection.
• username is the user name for this process's pool id connection.
• backend_connection_time is the creation time and date of the connection.
• client_connection_time is the date when a client last used this connection.
• client_disconnection_time is the date when a client last disconnected from this connection.
• client_idle_duration is the time (sec) that a client is in idle.
• If client_idle_limit is set not 0, the time before client disconnected is displayed.
• majorversion and minorversion are the protocol version numbers used in this connection.
• pool_counter counts the number of times this pool of connections (process) has been used by clients.
• pool_backendpid is the PID of the PostgreSQL process.
• pool_connected is true (1) if a frontend is currently using this backend.
• status is current status of this process. Possible values are:
• Execute command: Executing a command.
• Idle: The process is waiting for a new client command.
• Idle in transaction: The process is waiting for a new client command in a transaction.
• Wait for connection: The process is waiting for a new client connection.
• load_balance_node is true (1) if a frontend is currently using this backend and the backend is load
balance node.
It'll always return num_init_children * max_pool * number_of_backends lines. Here is an example session:
