A simple script to measure the time for a job pending in lsf.

1. This script simply measures the time a job is pending in lsf.


2. It can be a base for similar scripts, which measure a process duration, or trigger action upon process end detection.


3. First, statement in the script, a grep command is prepared. Then a while loop starts and continues as long as the grep command returns success status. The script has a 5 second sleep command in the while loop, in order not to load too much the CPU. The script calculates the elapsed time in seconds. Although I could just add 5 to a simple counter, in the script, (because the 5 second sleep command), I decided to use date command, as shown below.
   
     eval $cmd
     sleep 5
     time_end=`date +%s`
     time_tot=$(($time_end - $time_start))
     echo -ne "${time_tot} seconds\r"
   
   Note: that
   date +%s
   did not work on SunOS and did work well a linux machine. Instead I use perl to get the time for the bash script:
   time_start= `perl -e '$t=time(); print("$t\n")'`
   
   A nice display for the total time consumed is also added. The number of seconds is converted to minutes and hours if the value is greater than 60 / 3600 respectively.
   
   1. div="60"
      
   2. if [ "${time_tot}" -gt "$div" ] ; then
      
   3.   time_tot_m=$(($time_tot / $div))
      
   4.   time_tot=$(($time_tot % $div))
      
   5.   if [ "${time_tot_m}" -gt "$div" ] ; then
      
   6.     time_tot_h=$(($time_tot_m / $div))
      
   7.     time_tot_m=$(($time_tot_m % $div))
      
   8.   else
      
   9.     echo "job is not pending any more "${time_start}" "$time_end" "${time_tot_m}" minutes "${time_tot}" seconds"
      
   10.   fi
       
   11. else
       
   12.   echo "job is not pending any more "${time_start}" "$time_end" "${time_tot}" seconds"
       
   13. fi
       
   
   


4. The script is available at: pending time measure bash script


5. Script invocation is as simple as:
   ~/bin/lsf_pend_time_measure.unx 1616161
   

Where 1616161 is the job number in lsf.
