--- name: "SHOW_POOL_POOLS" section: "1" platform: "linux" package: "pgpool2" version: "4.6.1-2" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/SHOW_POOL_POOLS" --- # SHOW\_POOL\_POOLS(1) sends back a list of pools handled by Pgpool-II. ## 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.
