How to measure progress on the path of dhamma?

Sometimes the meditation is good and sometimes it is chaos. I follow the eightfold path as much as I can. I feel the progress is solely dependent on 'samma samadhi'. I dont have ill will or anger or hatred or sorrow anymore. Still I think progress in meditation is measure of how much one has progressed on the path of dhamma. But this is frustrating as I am not able to reach the elusive jhanas. How do I comfort myself that I am making progress each day on the path of dhamma?
