DataStage通过分析日志获取Job插入目标表的记录数
这只是一种不太好的方法，也许还有更好、更简便的方法。这种方法要求每次运行Job之前删除已有的日志信息，否则无法统计出正确的记录数。当然，在Job跑完之后，可以在shell备份本次Job运行的日志到服务器磁盘。
登录Datastage Administrator，选择对应项目，项目属性->记录，勾选“自动清除作业日志”，设置为自动清理上次及以前的日志。

在shell里用dsjob调起来Job，Job运行之后，将本次Job的日志备份到磁盘。
$DSHOME/bin/dsjob -logsum $projectName $jobName > $sysLogDir/$jobName.txt
注意到往目标表里写记录的时候会有关键字“Number of rows inserted:”或“Number of rows rejected:”，后面跟记录的数目。考虑到可能有多个节点，因此可以将各个节点的数据都加起来。
#inserted rows
insertedRows=`cat $sysLogDir/$jobName.txt | grep "Number of rows inserted:" | awk -F: ‘{print $3}‘ | sed ‘s/,/‘‘/‘ | awk ‘{sum=sum+$1;} END {print sum}‘`
#rejected rows
rejectedRows=`cat $sysLogDir/$jobName.txt | grep "Number of rows rejected:" | awk -F: ‘{print $3}‘ | sed ‘s/,/‘‘/‘ | awk ‘{sum1=sum1+$1;} END {print sum1}‘`
考虑到Job可能没进数就终止了，需要在接下来做处理。例如为空的话赋值0。
if [ ! -n "$insertedRows" ]; then
insertedRows=0
fi
监控可能还要些Job运行起止时间、结束状态等等，可以一并加上，然后写入一个日志文件。
其中起止时间可以在Job运行前后记录，Job的运行装可以用dsjob –run –status获取。
jobsta=$($DSHOME/bin/dsjob -run -mode NORMAL $jobParameters -warn 0 -jobstatus $projectName $jobName 2>&1 | awk -F= ‘/^Status code/{print $2}‘)
Job执行完毕之后，将该Job的一些监控信息写入日志。
echo $projectName $jobName $jobsta `date +%Y-%m-%d" "%H:%M:%S` $startTime $insertedRows $rejectedRows >> $logdir/job_run_` date +%Y%m%d`.log
当所有的Job都执行完之后，可以建立一个Job，将记录在$logdir/job_run_` date +%Y%m%d`.log中的数据抽取到一个表，用于查看。
