Creates a background thread that periodically send a registration notice.
The actual registration notices comes from the ‘body’ method of the registration plugins.
# File lib/mcollective/registration/base.rb, line 19 def run(connection) return false if interval == 0 Thread.new do loop do begin publish(body) sleep interval rescue Exception => e Log.error("Sending registration message failed: #{e}") sleep interval end end end end
