logging_module

参数说明：用于设置或者显示模块日志在服务端的可输出性。该参数属于会话级参数，不建议通过gs_guc工具来设置。

该参数属于USERSET类型参数，设置请参考表1中对应设置的方法进行设置。

取值范围：字符串

默认值：LOCK模块日志在服务端输出，其他模块日志在服务端不输出，可由SHOW logging_module查看：

ALL,on(LOCK),off(COMMAND,DFS,GUC,GSCLEAN,HDFS,ORC,SLRU,MEM_CTL,AUTOVAC,CACHE,ADIO,SSL,GDS,TBLSPC,WLM,OBS,INDEX,EXECUTOR,OPFUSION,GPC,GSC,VEC_EXECUTOR,STREAM,LLVM,OPT,OPT_REWRITE,OPT_JOIN,OPT_AGG,OPT_CHOICE,OPT_SUBPLAN,OPT_SETOP,OPT_SKEW,OPT_PLANNER,OPT_STAT_EXT,UDF,COOP_ANALYZE,WLMCP,ACCELERATE,MOT,PLANHINT,PARQUET,PGSTAT,CARBONDATA,SNAPSHOT,XACT,HANDLE,C LOG ,EC,REMOTE,CN_RETRY,PLSQL,TEXTSEARCH,SEQ,REDO,FUNCTION,PARSER,INSTR,WDR_SNAPSHOT,WDR_REPORT,INCRE_CKPT,INCRE_BG_WRITER,DBL_WRT,RTO_RPO,HEARTBEAT,COMM_IPC,COMM_PA RAM ,TIMESERIES,SCHEMA,SEGMENT_PAGE,LIGHTPROXY,HOTKEY,THREAD_POOL,OPT_AI,WALRECEIVER,USTORE,UPAGE,UBTREE,UNDO,TIMECAPSULE,GEN_COL,DCF,DB4AI,PLDEBUGGER,ADVISOR,SEC,SEC_FE,SEC_LEGER,SEC_POLICY,SEC_SDD,SEC_TDE,COMM_PROXY,COMM_POOLER,VACUUM,JOB,SPI,NEST_COMPILE,RESOWNER,GSSTACK,LOGICAL_DECODE,GPRC,DISASTER_READ,STANDBY_READ,REPSYNC,SQLPATCH,PARTITION,UBT_NEWPAGE,GPI,GS_DEPENDENCY,LWLOCK,GSI)

当前版本CN_RETRY不生效。

设置方法：首先，可以通过SHOW logging_module来查看哪些模块是支持可控制的。例如，查询输出结果为：

  
       gaussdb=# show logging_module;
logging_module
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(1 row)

支持可控制的模块使用大写来标识，特殊标识ALL用于对所有模块日志进行设置。可以使用on/off来控制模块日志的输出。设置SSL模块日志为可输出，使用如下命令：

  
       gaussdb=# set logging_module='on(SSL)';
SET
gaussdb=# show logging_module;                                                                                                                                              logging_module

可以看到模块SSL的日志输出被打开。

ALL标识是相当于一个快捷操作，即对所有模块的日志可输出进行开启或关闭。

  
       gaussdb=# set logging_module='off(ALL)';
SET
gaussdb=# show logging_module;                                                                                                                                                logging_module
