To uninstall NSP Flow Collector Controllers

Purpose

Perform this procedure to remove the NSP Flow Collector Controller software from one or more stations.

An NSP Flow Collector Controller uninstallation backs up the component configuration files in the /opt/nsp/backup_flow directory on the station. A subsequent NSP Flow Collector Controller installation on the station automatically reloads the saved configuration files. If you do not want the previous configuration restored during a subsequent installation, you must delete the /opt/nsp/backup_flow directory before the installation.

Note: If an NSP Flow Collector Controller is collocated on a station with an NSP Flow Collector, uninstalling the Flow Collector Controller also uninstalls the Flow Collector.

Note: You require the following user privileges:

  • on the station that hosts the NSP installer software—root

  • on each NSP Flow Collector Controller station—nsp

Note: The following RHEL CLI prompts in command lines denote the active user, and are not to be included in typed commands:

  • # —root user

  • bash$ —nsp user
