NetApp Harvest Failed to normalize unit

raph025 — Wed, 04 Jun 2025 13:16:44 GMT

Hello All,

In order to be able to solve problems of data transfer with Dataontap 8.2.5, I installed a new grafana.

I have the latest versions of graphite and Grafana 5.2.4 and NetApp Manager 1.4.1.

ISSUE :

Under grafana I have feedback information but my logs go back many warnings like :

[2018-09-25 10:52:05] [WARNING] Failed to normalize unit val=[257067423] unit=[wafl_block]
[2018-09-25 10:52:05] [WARNING] Failed to normalize unit val=[823418] unit=[wafl_block]

[2018-09-25 10:54:04] [WARNING] Failed to normalize unit val=[85081396] unit=[wafl_block]

I have arround 40 warning messages by Controler

Do you have an idea ?

Many thanks

Raphael.

Hi Raphael,

I looked at Harvest code and this message shouldn't happen, as "wafl_block" is a unit that should be taken care of.

Do you have "normalized_xfer" parameter in the harvest config file?

Are you absolutely sure this isn't an old version of Harvest?

Thanks you for your reply.

Yes, i have "normalized_xfer = gb_per_sec" in netapp-harvest.conf

Yes sure, this isn't an old version of Harvest .. 😞

Regards

It could be a bug indeed.

If you switch to mb_per_sec it should be fine.

You can also patch netapp-worker and add on line 2606 :

return ($val * 0.000003814697266) if ($connection{normalized_xfer} eq 'gb_per_sec');

For anyone else observing the same issue: I will post a patch that will fix this (as well as one other) bug in your Harvest installation. Hopefully by tomorrow 🙂
