datastage 分析日誌獲取表記錄條數

DataStage經過分析日誌獲取Job插入目標表的記錄數

這只是一種不太好的方法，也許還有更好、更簡便的方法。這種方法要求每次運行Job以前刪除已有的日誌信息，不然沒法統計出正確的記錄數。固然，在Job跑完以後，能夠在shell備份本次Job運行的日誌到服務器磁盤。

1       日誌清理設置

登陸Datastage Administrator，選擇對應項目，項目屬性->記錄，勾選「自動清除做業日誌」，設置爲自動清理上次及之前的日誌。

2       日誌處理

2.1     日誌備份（dsjob -logsum）

在shell裏用dsjob調起來Job，Job運行以後，將本次Job的日誌備份到磁盤。

$DSHOME/bin/dsjob -logsum $projectName $jobName > $sysLogDir/$jobName.txt

2.2     記錄數分析（grep、awk）

注意到往目標表裏寫記錄的時候會有關鍵字「Number of rows inserted:」或「Number of rows rejected:」，後面跟記錄的數目。考慮到可能有多個節點，所以能夠將各個節點的數據都加起來。

#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}'`

         考慮到Job可能沒進數就終止了，須要在接下來作處理。例如爲空的話賦值0。

if [ ! -n "$insertedRows" ]; then

         insertedRows=0

fi

2.3     其餘監控信息

監控可能還要些Job運行起止時間、結束狀態等等，能夠一併加上，而後寫入一個日誌文件。

其中起止時間能夠在Job運行先後記錄，Job的運行裝能夠用dsjob –run –status獲取。

jobsta=$($DSHOME/bin/dsjob -run -mode NORMAL  $jobParameters  -warn 0  -jobstatus  $projectName $jobName  2>&1  | awk -F= '/^Status code/{print $2}')

2.4     Job日誌記錄

Job執行完畢以後，將該Job的一些監控信息寫入日誌。

echo $projectName $jobName $jobsta `date +%Y-%m-%d" "%H:%M:%S` $startTime $insertedRows $rejectedRows >> $logdir/job_run_` date +%Y%m%d`.log

3       其餘（監控相關）

當全部的Job都執行完以後，能夠創建一個Job，將記錄在$logdir/job_run_` date +%Y%m%d`.log中的數據抽取到一個表，用於查看。

3.1     表設計

//日誌表

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

)

//日誌狀態表

create table DSLogState

(

state varchar (20),

mark varchar (50 ),

des varchar (500)

)
