I want to get a breakdown of the total read/write/other IOPS over a specific period, say 24 hours or a week for example. OCUM only seems to provide avg/min/max - is there a way to get the total performance data I want a different way?
I normally prefer to investigate performance related events through Grafana (NAbox) graphs. AIQUM is very nice though.... I think it's more a personal preference because once you get used to AIQUM, you do almost the same tasks in terms of analyzing graphs and etc.
If you don't ever used NAbox, you should give it a try. It looks faster and more fluid to pin point those IOPS/latency/Throughtput events using graphs and different time frames.
The screenshot @pedro_rocha provided is captured from a NAbox deployment that @robverhoeven suggested earlier in the thread. NAbox leverages NetApp Harvest, Graphite, and GrafanaLabs to provide a customizable holistic view. Harvest is the data collector, Graphite is the metrics database, and Grafana provides the dashboards.
There is a short intro video, screenshots and everything you need to setup NAbox .
