sudo gem install term-ansicolor
sudo gem install daemons

install xinuc-sermont from github.com

sudo gem install xinuc-sermont --source=http://gems.github.com

Run

sermont --setup

it will copy .sermont.yml to your home directory. Edit this file according to your servers.

---
- servername: Your server name
  ip: 127.0.0.1
  services:
    ftp: 21
    http: 80

Now, you can run sermont to monitor your servers.

If you have any services that can’t be checked by simply open the port, you can add you own service handler. As an example, if you want to check ‘weird’ service by your own method, you can create a file name “weird.rb” under YOUR_HOME_DIR/.sermont/ Then, the file should be like :

# file: weird.rb

def weird(host, port)
  # your own checking algorithm
  # this method should return true if the service is running
  # and false if the service is stopped.
