In database multiplexing mode, Mirroring Controller periodically accesses the database to check the multiplexing status and detect failure. Due to this, audit logs are also periodically retrieved, so log files become used up. Therefore, set the parameters below so that audit logs are not retrieved by Mirroring Controller.

postgresql.conf

log_connections

Omit, or specify "off".

log_disconnections

Omit, or specify "off".

serverIdentifier.conf file of Mirroring Controller

target_db

Specify "template1".

Note

If creating a new database, create it after stopping Mirroring Controller, or specify a name other than "template1" for the template database.

pgaudit configuration file

option section audit_log_disconnections

If you want to output disconnection logs for connections other than Mirroring Controller, specify audit_log_disconnections = "on".

rule section database

Specify database != 'template1'.
