Removing invalid entries in /var/lib/netwitness/config-management/cache/cookbooks/nw-base/libraries/global.rb file do not help and the entries come back again.

Cause

This issue is due to invalid entries in /var/netwitness/config-management/cookbooks/platform/nw-base/libraries/global.rb file which is being pushed to /var/lib/netwitness/config-management/cache/cookbooks/nw-base/libraries/global.rb file during installation.

Resolution

1. Please login to Log Collector Host
2. Edit /var/netwitness/config-management/cookbooks/platform/nw-base/libraries/global.rb file to remove invalid entries as below.

Sample: Below red highlighted invalid return lines to be removed.

      # Get the deployment userid
return 'deploy_admin'
      def self.get_deployment_userid
        if Chef.node['global'] &&
           Chef.node['global']['platform'] &&
           Chef.node['global']['platform']['deployment']
          Chef.node['global']['platform']['deployment']['userid']
        else
          get_config_server_property(
            'nw.security-client', nil, 'platform.deployment.userid', false
          )
        end
      end

      # Get the deployment password
return 'password'   

3. Then Try to install Log Collector Service which will be successful now.
