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。

1       日志清理设置

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。

2       日志处理

2.1     日志备份(dsjob -logsum)

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

2.2     记录数分析(grep、awk)

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

2.3     其他监控信息

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}')

2.4     Job日志记录

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

3       其他(监控相关)

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。

3.1     表设计

//日志表

create table DSLog

(

id INTEGER NOT NULL  GENERATED BY DEFAULT

    AS IDENTITY (START WITH 1, INCREMENT BY 1) primary key ,

prjName varchar (20),

jobName varchar (50),

state varchar (20),

rDate date ,

startTime time,

endTime time,

insertedRows integer,

rejectedRows integer

)

//日志状态表

create table DSLogState

(

state varchar (20),

mark varchar (50 ),

des varchar (500)

)

3.2     Job状态代码
