Total IOPS

tyrone_owen_1

Hi,

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?

Thanks

Hi,

I think NetApp Harvest or NABox can help out here. Check https://nabox.org for more details.

Cheers,

Rob

You will find the QOS commands useful to what you are looking for.

Thanks very much for the reply.

Doesn't the qos command provide current statistics as opposed to a total over a 24 hour/week period?

Thanks Rob, that looks interesting - why would I use it over OCUM?

Looking at the screen shots I see avg/max/min IOPS and not total IOPS broken down into r/w/o for a given period.

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.

Hi,

I'm not investigating a performance issue.

Just to restate the request: is there any way for me to establish the Total read/write/other IOPS for a defined period? Preferably using native tools, e.g. CLI, OCUM....

Thanks

Hi Tyrone_owen_1,

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 .

Regards,

Team NetApp

Just to confirm then, as no-one has said specifically, there is no way to do this with native NetApp tooling?

In OCUM there is no presentation of the total IOPS for a period of time - like 24 hours. However in the zoom view shown above you will get the average of the IOPS over the period of time. That can be used to calculate the total IOPS as (average IOPS * number of seconds in the period of time of interest). This number will grow quickly with the length of the period of time. For this reason, i.e., avoid large numbers, OCUM shows only averages of IOPS.

For 72 hour period there is an inventory page that lists all the volumes and displays the average IOPS - again from there one can calculate the total IOPS for 72 hours.

Thanks for the response.

Unless I am missing something, your calculation assumes that the average IOPs for every second during a given period is absolutely consistent, which in many systems I'm sure this is the case.
