Question on io monitoring tools such as gstat and iostat
I am relatively new to using IO monitoring tools and wanted to confirm I understand them correctly. If I specify an interval of 5 seconds, my assumption is that the data displayed is an average over that 5 second interval. Is that correct or am I misunderstanding how intervals work? Thanks!
