Postgresql的日志配置教程详解_PostgreSQL_

 # This is used when logging to stderr: logging_collector =on# Enable capturing of stderr and csvlog # into log files. Required to be on for # csvlogs. # (change requires restart)

 # These are only used if logging_collector is on: #配置日志目录，默认为pg_log即可 log_directory = 'pg_log' # directory where log files are written, # can be absolute or relative to PGDATA #pg日志文件名及其扩展名，默认即可 log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' # log file name pattern, # can include strftime() escapes #pg日志文件的权限，默认即可 log_file_mode = 0600 # creation mode for log files, #开启日志滚动阶段，这里需要设置为on log_truncate_on_rotation =on# If on, an existing log file with the #日志保留天数，这里看实际环境，如果是测试建议1d，如果是生产环境建议7d log_rotation_age = 1d # Automatic rotation of logfiles will #单个日志大小，默认100MB即可，比较标准的配置 

 #发送给客户端的消息级别，建议warning即可，日志等级越低，打印的内容越多，性能上越有损耗 client_min_messages = warning # values in order of decreasing detail: # debug5 # debug4 # debug3 # debug2 # debug1 # log # notice # warning # error #写到数据库日志文件中的消息的级别，建议warning即可，日志等级越低，打印的内容越多，性能上越有损耗 log_min_messages = warning # values in order of decreasing detail: # debug5 # debug4 # debug3 # debug2 # debug1 # info # notice # warning # error # log # fatal # panic #是否记录导致数据库出现错误的SQL语句，建议warning即可，日志等级越低，打印的内容越多，性能上越有损耗 log_min_error_statement = error # values in order of decreasing detail: # debug5 # debug4 # debug3 # debug2 # debug1 # info # notice # warning # error # log # fatal # panic (effectively off)

 #log_statement_stats为on则会开启log_parser_stats，log_planner_stats，log_executor_stats这三个选项，生产环境不建议开启，建议测试环境开启，用于定位问题。 #log_parser_stats = off #log_planner_stats = off #log_executor_stats = off #log_statement_stats = off 

 #执行sql时间为2s以上的sql都会被记录下来 log_min_duration_statement = 2s
