Abstract
Aspects of the technology provide methods for simulating a failure in a tenant network. In some aspects, a monitoring appliance of the disclosed technology can be configured to carry out operations for receiving packets at a virtual device in the monitoring appliance, from a corresponding network device in the tenant network, and instantiating a firewall at the virtual device, wherein the firewall is configured to selectively block traffic routed from the network device to the virtual device in the monitoring appliance. The monitoring appliance can simulate failure of the network device by blocking traffic from the network device to the virtual device using the firewall, and analyze the tenant network to determine a predicted impact a failure of the network device would have on the tenant network. Systems and machine-readable media are also provided.
