Since process start, the averages are updated every stats_period. In this and related commands, the total figures are Some drivers use the extended query protocol for all commands theseĭrivers will not work for this. The admin console currently only supports the simple query protocol. If the login comes via the Unix socket and the client has same Unix user UID (Except when auth_type=any, thenĪdditionally, the user name pgbouncer is allowed to log in without password, Only users listed in the configuration parameters admin_users or stats_usersĪre allowed to log in to the console.

That means connecting to the running process, Note: Does not work on Windows pgbouncer need to run as service there. No log messages will be written to stderr after In daemon mode, setting pidfile as well as logfile or syslog Without it, the process will run in the foreground.
