Monitoring scheduling for home gateways

In simple and monolithic systems such as our current home gateways, monitoring is often overlooked: the home user can only reboot the gateway when there is a problem. In next-generation home gateways, more services will be available (pay-per-view TV, games...) and different actors will provide them. When one service fails, it will be impossible to reboot the gateway without disturbing the other services. We propose a management framework that monitors remote gateways. The framework tests response times for various management activities on the gateway, and provides reference time/performance ratios. The values can be used to establish a management schedule that balances the rate at which queries can be performed with the resulting load that the query will induce locally on the gateway. This allows the manager to tune the ratio between the reactivity of monitoring and its intrusiveness on performance.
