1、使用GGSCI命令监控
（1）进入GoldenGate安装目录，运行GGSCI，然后使用info all查看整体的运行状况
GGSCI (aix212) 1> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
EXTRACT RUNNING EORA_1 00:00:00 00:00:03
EXTRACT RUNNING PORA_1 00:00:00 00:00:00
GGSCI (aix211) 1> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
REPLICAT RUNNING RORA_1 00:00:00 00:00:09
Group表示进程的名称（MGR进程不显示名字）；
Lag表示进程的延时；Status表示进程的状态，有4种状态。
STARTING 表示正在启动过程中。
RUNNING 表示进程正常运行。
STOPPED 表示进程被正常关闭。
ABENDED 表示进程非正常关闭，需要进一步调查原因。
正常情况下，所有进程的状态应该为RUNNING，且Lag应该在一个合理的范围内。
（2）使用view params <进程名> 可以查看进程的参数设置，该命令支持通配符*
源端：
GGSCI (aix212) 4> view param mgr
dynamicportlist 7800-8000
autorestart extract *,waitminutes 2,resetminutes 5
GGSCI (aix212) 7> view param eini_1

DISCARDFILE ./dirrpt/RORA_aa.DSC,PURGE
MAP scott.oem_ogg, TARGET scott.emp_ogg;
（3）使用info <进程名称> 命令可以查看进程信息，可以查看到的信息包括进程状态、checkpoint信息、延时等
GGSCI (aix212) 8> info eora_1
EXTRACT EORA_1 Last Started 2014-09-25 16:09 Status RUNNING

（4）还可以使用info <进程名称> detail 命令查看更详细的信息，包括所使用的trail文件、参数文件、报告文件、警告日志的位置等
GGSCI (aix212) 10> info eora_1 detail
EXTRACT EORA_1 Last Started 2014-09-25 16:09 Status RUNNING

（5）使用info <进程名称> showch 命令可以查看到详细的关于checkpoint的信息，用于查看GoldenGate进程处理过的事务记录

其中比较重要的是Extract进程的recovery checkpoint，它表示源数据中最早的未被处理的事务；通过recovery checkpoint可以查看到该事务的redo log位于哪个日志文件以及该日志文件的序列号。
所有序列号比它大的日志文件，均需要保留。
（6）lag <进程名称> 可以查看详细的延时信息
GGSCI (aix212) 12> lag eora_1
Sending GETLAG request to EXTRACT EORA_1 ...

At EOF, no more records to process.
（7）stats可以查看进程处理的记录数：
该报告会详细地列出处理的类型和记录数，例如：

2、ggserr.log日志监控
（1）可以用以下方法查看日志文件。
可以通过操作系统命令直接查看ggserr.log文件。
使用GoldenGate Director。
在GGSCI中运行命令view ggsevt。
（2）在日志文件中可以查看到的内容如下。
GGSCI命令的历史记录。
GoldenGate进程的启动与停止。
已执行的处理。
