Issue/Introduction

Observed a  robot is sending qos for cdm, sometimes every minute, sometimes more. 

Upgraded to newer versions of cdm probe , but still the same is observed

eg: here is one disk drive from the DB. Samplerate is 720 (12mins), but as you can see the sampletimes are 13:05, 13:04, 13:03, 13:02 etc

This seems to happen for most metrics in cdm. CPU/Disk/Mem/Uptime.

Environment

Release : 9.0.2/20.x/20.4.x

Component: UIM - CDM WITH IOSTAT

OS: Linux 2.6.32-754*

Cause

- cdm data originating from a cloned robot.

Resolution

Observed cdm data in DrNimbus message sniffer even when the cdm probe is stopped, so this data is coming from a cloned robot in the environment.

Identify the clone and stop it / clear niscache of cloned robot  to resolve the issue.
