Uninstall NetQ

This page outlines how to remove the NetQ software from your system server and switches.

Remove the NetQ Agent and CLI

Use the apt-get purge command to remove the NetQ Agent or CLI package from a Cumulus Linux switch or an Ubuntu host:

cumulus@switch:~$ sudo apt-get update
cumulus@switch:~$ sudo apt-get purge netq-agent netq-apps
Reading package lists... Done

0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
After this operation, 310 MB disk space will be freed.

...

If you only want to remove the agent or the CLI, but not both, specify just the relevant package in the apt-get purge command.

To verify the removal of the packages from the switch, run:

cumulus@switch:~$ dpkg-query -l netq-agent
dpkg-query: no packages found matching netq-agent
cumulus@switch:~$ dpkg-query -l netq-apps
dpkg-query: no packages found matching netq-apps

Use the yum remove command to remove the NetQ agent or CLI package from a RHEL7 or CentOS host:

root@rhel7:~# sudo yum remove netq-agent netq-apps
Loaded plugins: fastestmirror

Uninstall NetQ from the System Server

First remove the data collected to free up used disk space. Then remove the software.

  1. Log in to the NetQ system server.

  2. Remove the data using the following command. For cluster deployments, run this command on each node in the cluster:

netq bootstrap reset purge-db
  1. Remove the software with apt-get purge:
cumulus@switch:~$ sudo apt-get update
cumulus@switch:~$ sudo apt-get purge netq-agent netq-apps
  1. Verify the removal of the packages from the switch:
cumulus@switch:~$ dpkg-query -l netq-agent
dpkg-query: no packages found matching netq-agent
cumulus@switch:~$ dpkg-query -l netq-apps
dpkg-query: no packages found matching netq-apps
  1. Delete the virtual machine according to the usual VMware or KVM practice.

Delete a virtual machine from the host computer using one of the following methods:

  • Right-click the name of the virtual machine in the Favorites list, then select Delete from Disk.
  • Select the virtual machine and choose VM > Delete from disk.

Delete a virtual machine from the host computer using one of the following methods:

  • Run virsch undefine <vm-domain> --remove-all-storage
