Unable to Calculate Disk IOPS for watcher

[Himanshu_Rajput]

Hi,

I want to implement a watch over marvel data for disk IOPS. All the fields under node_stats.fs.data are in long which contains bytes. I want to calculate disk IOPS from these fields such as this

Is there any formula for this ?

hey,

can you explain what you mean with calculate in this context? This graph is just displaying the results of a query without calculating anything.
