Issue/Introduction

We are seeing a lot of these messages in the karaf.log on the DA.

WARN | uler-thread-1466 | 2021-01-13 23:01:54,186 | NormalizedFacetSource | lizer.impl.NormalizedFacetSource 282 | .im.aggregator.discovery | | Unable to find MetricFamilyVendorPriority item for MF {http://im.ca.com/normalizer}NormalizedStorageVfilerInfo

This problem always happens from 01:00 until 06:00 and after that the data aggregator syncs again and the errors stop.

Cause

What these lines tell you is change detection is running (update metric families), so there is a lot of item repository use/updates going on, and possibly DB changes.

Environment

Release : 20.2

Component : IM Polling

Resolution

The WARN messages can be ignored.

In a future version we will change these WARN to a DEBUG message.
