Abstract: There is provided an apparatus for remotely monitoring a computer network. Monitoring is performed using an inside out approach from behind firewalls and other security devices. The monitoring appliance is shipped to a client site preconfigured and typically requires no technically trained person for installation. Collected network data is periodically transmitted to a remote monitoring facility where it is recorded and analyzed. Both the monitoring appliance and the remote center maintain the configuration data. Typically, no client data is transmitted to the remote monitoring site. If the monitoring appliance fails, a completely configured replacement may be shipped to the site and easily installed. The monitoring appliance is optionally equipped to provide network services.
