Here is my code:
File ol_ohai_plugin.rb has the following content

Ohai.plugin(:ol_ohai_plugin) do
  provides "oci_ol_km"
  collect_data(:default) do
    oci_ol_km Mash.new
    oci_ol_km[:ipaddress]="127.0.0.1"
  end
end

File - recipes/ol_translator.rb

`require 'json'

ohai_plugin 'My Ohai Plugin' do
  name 'ol_ohai_plugin'
  path '/var/tmp'
end

puts "**********************************"
puts node[:oci_ol_km][:ipaddress]
puts "**********************************"

`
When I run this code from my workstation on a node 'node10', I am not seeing my node attributes populated in the node object under 'automatic'.

From my workstation, I run it as follows:
knife ssh ip_address_of_node_10 'chef-client'
Please let me know what am I missing

I believe what you're running into is a compile time vs. converge time problem in your recipe. Chef runs in two different phases. The first is a compile time phase where Ruby is evaluated. The 2nd phase involves actually converging each of the resources. The puts statements are actually running before the plugin is installed since the puts statements happen in the compile phase. You can work around some of this by adding compile_time true to the ohai plugin, but also testing with puts is going to be problematic since it's running during compile time. For troubleshooting you might have a better time adding chef log resources to the recipe as those will execute during the converge.
