Configuring the Ruby data collector for IBM Cloud applications

To collect information about Ruby applications on IBM® Cloud, you must configure the Ruby data collector.

1. Extract files from the data collector package. The ruby_datacollector_8.1.4.0.tgz package is included in the extracted directory.
2. Extract the files in ruby_datacollector_8.1.4.0.tgz by running the following command:

   tar -zxf ruby_datacollector_8.1.4.0.tgz

   You get an ibm_ruby_dc folder.
3. Copy the entire etc folder in ibm_ruby_dc to the root folder of you Ruby application by running the following command:

   cp –r directory to the etc folder  home directory of your Ruby application

   The following command extract the data collector to the /opt/ibm/ccm/ibm_ruby_dc/etc directory and the home directory of your Ruby application is /root/ruby_app/:

   cp –r /opt/ibm/ccm/ibm_ruby_dc/etc /root/ruby_app/

4. Add the following section to the Gemfile in the home folder of your Ruby application:

   gem 'logger',  '>= 1.2.8'
   source 'https://maagemserver.ng.bluemix.net/' do
     gem 'ibm_resource_monitor'
     gem 'stacktracer'
   end

5. Run the bundle lock command to regenerate the Gemfile.lock file.
6. From the directory that contains the manifest.yml file of your Ruby application, run the following command:

   cf push
