Hello.

First, thank you to the Harvest team. We found that it made NetApp monitoring smoother.

I want to know the exact units of that value

We have Grafana - InfluxDB2 - Harvest

I would like to ask about the units of the two field values here

measurement = flashpool

fields:
hya_write_hdd_latency_average
hya_write_ssd_latency_average

This seems to be too high a ratio to be expressed in milliseconds

average 200ms ~ 800ms. sometimes 1.5seconds over.

similar vaule hya_read_hit_latency_average and hya_read_miss_latency_average is 0.5ms ~ 10ms average

Can I know about this?

@potent grove Could you share Harvest version?

ONTAP docs don't show the unit for this. As @remote drift mentioned, this metric can be found in the Harvest metrics documentation.

https://netapp.github.io/harvest/24.02/ontap-metrics/#flashpool_hya_write_ssd_latency_average

We'll check with ONTAP team and get back to you on this.

Let me see if I can get it.

#

Looks like it's milliseconds.

Do you have a case open? Please e-mail me first name dot last name at thestorage vendor dot com. Sorry really obfuscated due to spam prevention.

Thanks @supple sapphire . ONTAP team has also confirmed, It is in ms

I'm sorry for late confirmation because I had some work to do.
We harvest version 24.02.0-1
Is ms correct?
The value was so high that I had doubts about the unit.
We will solve the problem in another way
Thank you for checking.

@potent grove Yes, it is ms
