Need logic for check automated Job work in awk or SED.

senthilkumar_ak · #1 (**permalink**) 09-01-2008

I have a Java program which will automatically trigger some scheduled job to update Db or some other work. I am tracking the jobs with log messages and finding out it is properly run or not. I want to write a script to capture it correctly on time.

Say Job1 is running on 15, 30, and 45 every hour then it leave an entry in the log file that “JOB1 is started”. Like this.

Example for hour 11:00 pm means –

Worker#Scheduler_Worker-3: 23:15:56 105 SendToCM: run() Entry

where “SendToCM: run() Entry” starting log message which Java program write in the log message, '23:15:56' is the time . I need to check the last hour 15 , 30, 45 min log files to find out the entry is their or not then I intimate via mail to me.

i have a logic but not tested yet. For 15 min I am checking with sed like this,

sed -n "/: $h:15:00/,/: $h:15:01/p" schedulerTrace .log > Job1.log

here $h contains the current hour and in the job1.log I’m checking again like

count=grep –c “SendToCM: run() Entry” Job1.log.

if count is zero then the JOB1 is not ran and I need to check exception.
But this logic is very oblique to me. Could you me please help me on finding out a correct logic for this.

Regards,
Senthilkumar.

Why not ignore the seconds component completely and just do something like:

Code:

if grep -q ": $h:15.*SendToCM: run()" schedulerTrace.log
then
      echo job did run
else
      echo job did not run
fi

Fantastic Annihilannic,

thanks for your suggestion. One more thing.

Is it possible for me to check all 15, 30,45 entires in one grep or i want to use a separte one.

So... you want to only run your check once an hour and see whether it has run three times?

Code:

if [[ "$(grep -Eqc ": $h:(15|30|45):.*SendToCM: run\(\)" schedulerTrace.log)" -eq 3 ]]
then
      echo job did run 3 times in the hour
else
      echo job did not run 3 times in the hour
fi

I'm assuming that there are only one day's worth of jobs in the log, otherwise of course you will match the previous day's jobs too.

Well yes you're right, the log files contains only one day logs. But with this condition i wont be check the job when not ran, so i modified little and used like this , please let me know if done some thing wrong.

# Loop to check the Job1 <Send To CM started properly or not>
if [ $min -ge 1 -o $min -lt 30 ]; then
count=`grep -ic ": $hr:01.*SendToCM: Start:" $logpath`
elif [ $min -ge 30 -o $min -le 59 ]; then
count=`grep -ic ": $hr:30.*SendToCM: Start:" $logpath`
fi
if [ $count -eq 0 ]; then
echo -e "\nThe Job1 Send To CM is not started as schdueld at 1 and 30" >> mail.log
fi

i will mail the mail.log at last after checking for other jobs too

I see nothing obviously wrong there.
