Week 14 practice

Python Practice

Assignment

This assignment will hone your skills as a Python script writer.

Tasks

Create the following script using python:

• You script should login to several hosts and check to make sure that services are on. If services are not on, an email alert should be sent to you.
• This should be ran as a cron job every hour.

• You should begin with a hosts file that has the following format:

    host1:process_to_check
    host2:process_to_check
    host3:process_to_check
    host4:process_to_check
  

Maybe something like:

    1.1.1.1:mysql
    1.1.1.2:apache2
    1.1.1.3:bind9
    1.1.1.4:bind9

• Make sure you can write an appropriate shell command to see if a process is running (i.e. system apache2 status, then grep what you want from there)
• The script should be run like this: ./process_monitor.py hostlist
