OK I noticed a change in the way NABOX , Graphana , Harvest displays metrics related to Flash Cache and READS from SSD after CDOT upgrade from 9.4X to 9.5X - 3 different clusters / 3 diff upgrate dates / all display same characteristics - so is it just the way NABOX charts these metrics now or was the Algorithms for Flash Cache and READS from SSD modified in 9.5X ? thanks.
TMAC - thanks for your help, thru this tread I was able to update the SDK componenet and the Harvest Component - so that was a plus 😉 - as far as the graphs related to " Flash Cache and READS from SSD" - it looks like the "scale" changed after the upgrade I mentioned - also I remember for the last 4 or 5 ONTAP versions the oncommand system manager displayed "flash cache" info for the AFF controllers when it should not have( AFF systems do not have "Flash Cache" cards ). So when all is said and done after the ONTAP upgrade to 9.5X the oncommand system manager DOES NOT display "flash cache" info for the AFF controllers and that is now correctly reflected in the NABOX charts / graphs.
