I'm attempting to pull the Top Disks by disk_busy chart from performance manager (DFM 5.1) but I'm getting 'No data is currently available for chart "Top Disks by disk_busy"'. I have four aggregates on the controller in question and I can get stats for two aggregates but not the other 2. I've diagnosed connectivity on the controller and all comes back ok:
and I've checked last sample time on the aggregate and it comes back being sampled 20 minutes ago?
Any ideas as to why these stats might be missing or how I can get Performance manager to pick them up?
I know DFM has it under physical or try statit. FY: The first disk in the RG will show much busier than other disks in the RG, according to NetApp this is normal. Output from statit -b, sleep for 2 min, then statis -e
