preview

description

Simple widget to ping a host and get color feedback, green => online red => offline

dependencies

net-ping

Add it to dashing's gemfile:

gem 'net-ping'

usage

To use this widget : create a directory /widgets/ping copy ping.html, ping.coffee, and ping.scss into the /widgets/ping directory. copy ping.rb into the jobs directory. add config.yml into the app root directory

ping:
  id:
    ip: IP
    name: HOST_NAME

id I choose to be a number, but need to match with what there is in dashboard.erb

setup

you can add many widget ping as you want, by modifing the list of hosts in config.yml and copy pasting the widget in the dashboard.erb if you have a lot of ping to do, you should consider increasing the screduler time inside jobs.rb specially if you have a lot of offline hosts

config.yml

ping:
  1:
    ip: 192.168.1.45
    name: surveillance
  2:
    ip: 192.168.1.46
    name: host_slave
  3:
    ip: 192.168.1.47
    name: host_master

dashboard.erb

<!-- for 3 ping widgets, for more copy paste a li tag and increment the data-id -->
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="ping_1" data-view="Ping" data-unordered="true"></div> 
</li>
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
   <div data-id="ping_2" data-view="Ping" data-unordered="true"></div>
</li> 
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
   <div data-id="ping_3" data-view="Ping" data-unordered="true"></div>
</li>
