Rails delayed jobs stops on staging

Question

How to figure out whether delayed job is running or not at background on staging.If it is stop so it should start running by checking some process pid or something .My problem is on staging delayed job stop sometimes and I am not able to figure it out why it happens so can any one tell me what should i possible do to solve this problem. This is the command i check for checking the status

RAILS_ENV=staging ./script/delayed_job status

but i need to do something which should check automatically whether delayed job is running or not .IF not it should start running

Answer 1

Create a shell script file in the root directory and place this code .
Then give permissions to the file

ps_out=`ps -ef | grep delayed | grep -v 'grep' | grep -v $0`
result=$(echo $ps_out | grep "$1")
if [[ "$result" != "" ]];then
    echo "Running"
else
    /path-to-your-project/delayed_job start
fi

Now add this in crontab

crontab -e
