NVMe dashboard

[ddhti]

Hi,

I'm using nabox 3.2 with harvest 23.02.0-1. I have NVMe LUNs (namespaces) in use but they are not under the LUNs dashboard and I can't find them elsewhere. There are NVMe stats under the SVM dashboard but that's it. ... Also, I don't see a storagegrid dashboard (but I haven't added my SG yet).

What step or config am I missing?

thank you.

@ddhti NABox has some pending work related to Storage Grid support. This feature is available in Harvest, and there are steps available on how it can be added in NABox, as mentioned on discord

Harvest exposes these NVME metrics, which can be found at this link.

Currently, no template is available in Harvest for the nvme_namespace object in ONTAP. Below are the available counters for this object. Are you looking for these metrics related to the NVME namespace in Harvest?

I see the NVMe network stats under the SVM dashboard but I guess I'm looking more for what I get with respect to LUNs (iscsi/FC..). I need to look at an individual LUN (namespace) and get stats pertaining to that particular storage.

As for StorageGrid I'll review the Discord link (thanks!) but it's lower priority for me.

thanks

Thanks @ddhti . Harvest will add this as part of issue #1829 for our upcoming release. We'll also let you know when it is ready for Test through our nightly build.
