Welcome to Day 65 of 100 Days of DevOps, Focus for today is Bash Script to Monitor Service

Step1: How to check if the service is running?

• There are a number of ways we can check it
• First approach netstat

# netstat -antulp|grep httpd
tcp6       0      0 :::80                   :::*                    LISTEN      19122/httpd

# ps aux|grep -v grep |grep -i httpd
