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。该参数依赖于log_min_messages参数的设置，低于log_min_messages设置级别的模块日志不会打印。

参数类型：字符串

参数单位：无

默认值：'off(ALL)'。即默认关闭所有模块日志。在PDB场景内，若未设置该参数，则继承来自全局的设置。

取值范围：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(),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,CBOPT_REWRITE,OPT_JOIN,OPT_AGG,OPT_CHOICE,OPT_SUBPLAN,OPT_SETOP,OPT_SKEW,OPT_PLANNER,OPT_STAT_EXT,SPM,SPM_KEY_FLOW,UDF,COOP_ANALYZE,WLMCP,ACCELERATE,PLANHINT,PARQUET,PGSTAT,CARBONDATA,SNAPSHOT,XACT,HANDLE,C LOG ,EC,REMOTE,CN_RETRY,PLSQL,TEXTSEARCH,SEQ,REDO,FUNCTION,PARSER,INSTR,WDR_SNAPSHOT,WDR_REPORT,ASP_REPORT,INCRE_CKPT,INCRE_BG_WRITER,DBL_WRT,RTO_RPO,HEARTBEAT,COMM_IPC,COMM_PA RAM ,TIMESERIES,SCHEMA,GTT,SEGMENT_PAGE,LIGHTPROXY,HOTKEY,THREAD_POOL,OPT_AI,WALRECEIVER,USTORE,UPAGE,UBTREE,UNDO,TIMECAPSULE,GEN_COL,DCF,AI4DB,DB4AI,ABO,MOD_ABOFEEDBACK,PLDEBUGGER,ADVISOR,SEC,SEC_FE,SEC_LEGER,SEC_POLICY,SEC_SDD,SEC_TDE,COMM_FRAMEWORK,COMM_PROXY,COMM_POOLER,COMM_STATUS,VACUUM,JOB,SPI,NEST_COMPILE,RESOWNER,GSSTACK,LOGICAL_DECODE,GPRC,DISASTER_READ,STANDBY_READ,REPSYNC,SQLPATCH,PARTITION,UBT_NEWPAGE,GPI,GS_DEPENDENCY,LWLOCK,LOCK,UNIQUE_SQL,GLC,SRF,DBLINK,BARRIER_CREATOR,EXRTO_PAGE_P,SEQ_TUP_P,BT_TUP_P,DISPATCH_VERIFY,HBKT,DBE_STATS,DBE_XMLGEN,GS_ILM,GSPERF,EXEC_REMOTE,UBTREE_PARA,BTREE_PARA,ANTI_CACHE,ANTI_RECYCLER,VERIFYLOG,GS_REPAIR,AUTHID,CCINDEX,ONLINE_DDL,MTD,EXRTO_BUFFER,STREAM_PBE,HTAP,UALT,GTM_LITE_READ_S,UGIN)

当前版本CN_RETRY不生效。

设置方式：该参数属于会话级参数，不建议通过gs_guc工具来设置。该参数可在PDB级别设置。

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

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
