Rolling back the Netprobe
The RollbackNetprobe.yaml CloudFormation template rolls back the Netprobe on existing EC2 instances using the AWS Systems Manager (SSM) by restoring the most recent backup archive created under <NetprobeInstallDirectory>/backup/netprobe/ and restarting the netprobe.service.
Prerequisites Copied
- The target EC2 instances must have an SSM Agent installed and running.
- Target instances must have an IAM instance profile attached with the following permissions:
AmazonSSMManagedInstanceCore(for SSM communication)
- The
netprobe.servicesystemd unit must exist on the instances. - A backup archive must exist at
<NetprobeInstallDirectory>/backup/netprobe/netprobe-*.tar.gz. This is created by the update process.
