Issue/Introduction

The remove_not_present_items.sh scripts returns "could not resolve any host" and  "not present/not polled" interfaces are still visible in the console.

Error seen in output: Could not resolve host:<HOSTNAME>

Environment

Dx NetOps Performance Management any version

Cause

This is an operating system (OS) level issue with resolving the hostname used.

You can verify with:

  • nslookup hostname
  • ping hostname

Replace hostname with the hostname you are trying to use with the script. 

Resolution

Correct the OS issue with name resolution or use the IP of the Data Aggregator instead of the hostname.
