Issue/Introduction

We are seeing these warnings in the karaf.log on the DA:

..

WARN | FacetBatcher | 2021-01-13 23:01:03,658 | nagedDeviceResourceDiscoveryImpl | nagedDeviceResourceDiscoveryImpl 771 | .im.aggregator.discovery | | Unable to retrieve mfInfo for key=MultiKey[125578, {http://im.ca.com/normalizer}NormalizedAddressInfo]

..

Usually they are seen between 1am and 5am then they 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.
