Issue/Introduction

Running a Low-Scale environment with both Data Aggregator (DA) and Data Collector (DC) running on the same server.

After configuring the Low-Scale environment the DA is owned by root and the DC is owned by a non-root sudo-root user.

Post Upgrade verification shows the following errors in the DC karaf.log file.

Environment

All supported DX NetOps Performance Management releases

Cause

Different services owned by different users.

Resolution

A Low-Scale shared server requires both DA and DC installs are owned by and managed by the same user.

Ensure both are installed using the same user to resolve the error.

The error is benign and can be ignored if desired.
