Purging AWS discovery and visibility systems - Adaptive Applications - BlueCat Gateway - 23.3.2

Cloud Discovery & Visibility Administration Guide

Product name
BlueCat Gateway

In order to perform Amazon Web Services (AWS) discovery and visibility jobs, CDV stores files, data, and other resources on the target AWS infrastructure. This data is used to track network resources like virtual networks, virtual machines, and load balancers (among others) so that they can be noted and passed on to Address Manager by visibility jobs. If you don't need to run discovery or visibility on a system anymore (or you simply want to clear out data for maintenance), you can purge it to remove these files.

CDV tracking resource files typically begin with the prefix BC-CDV-. Purging deletes all SNS, SQS, and CloudWatch resources that CDV uses to set up visibility on an AWS system. Purging removes only files that begin with BC-CDV-, plus files and data associated with discovery and visibility jobs that currently exist in CDV. When purging AWS systems, you can limit the purge operation to specific regions.

To purge an AWS visibility system:

  1. In CDV, go to the AWS Settings tab. (Click the AWS tab in the header, then click the Settings tab and expand Purge Visibility System.)

  2. Enter the access key, authentication, and role details for the target AWS infrastructure, then select the regions that you want to purge.

    The account used for purging must have the appropriate permissions for the selected regions.

    For more details, see Purging Visibility System settings below.

  3. When you're done, click Purge.
