When installing omg-aggmgr note the following:

1. In ogs.rb add variable that represents root directory of the application

   DEF_VAR_PATH ="/usr/share/omf-aggmgr-5.2/omf-aggmgr"
   

2. In method register in ogs.rb add root path to server content

   #Lets add root path to static server/service content
   cfg.merge!('varPath' => "#{DEF_VAR_PATH}")
   

3. Add file handler to public_html directory in startServer method. This is necessary for grid status front-end and for new scheduler developing.

     path = DEF_VAR_PATH + "/public_html" 
     @@server.mount("/public_html/", HTTPServlet::FileHandler, path) {
       raise HTTPStatus::NotFound, "#{path} not found."
     }
