Ensure 'log_timezone' is set correctly

低レベル 1自動yugabytedb

説明

The log_timezone setting specifies the time zone to use in timestamps within log messages. This value is cluster-wide, so that all sessions will report timestamps consistently. Unless directed otherwise by your organization's logging policy, set this to either GMT or UTC. Runs ysqlsh (add the YugabyteDB bin directory to PATH) against PGHOST/PGPORT (default 127.0.0.1:5433) as PGUSER (default yugabyte); supply the password through PGPASSWORD or ~/.pgpass. Passes when log_timezone is GMT or UTC; a different zone mandated by your logging policy is an accepted exception.

Set it with the YB-TServer GFlag --ysql_pg_conf_csv="log_timezone='UTC'" on every YB-TServer and restart it.
