This is what I observed. I set es\_heap\_size from 2000m to 3000m (on 6gb machine) and restart ES service and marvel still shows the machine as having 2gb. I restarted the machine itself and still the same. I finally got Marvel to show the right data when i uninstalled and reinstalled the service. Am I doing something wrong or is this expected? Where does ES store the value internally? Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
