For example, for our network devices, the configuration files are somewhere static, they do not change often. So using a rest API to take a nightly snapshot of the configuration file for backup is probably good enough. However, on the other hand, what if we need to keep track of the route changes in our routing table? or keep track of our BGP neighbor flapping changes.
