The disclosure relates to automating a balanced configuration of traffic monitoring filters to monitor traffic in a production network. A deployment in accordance with the disclosure includes a production network and a monitoring fabric. The production network includes a network controller to configure and provide information about the production network, and likewise the monitoring fabric includes a controller to configure and provide information about the monitoring fabric. A filter agent can create traffic monitoring rules that constitute user-defined traffic monitoring filters, and deploy the rules in a balanced fashion across devices in the production network and in the monitoring fabric using information queried from the production network controller and the monitoring fabric controller. The filter agent can redeploy traffic monitoring rules in response to changes in the operating environment.

Automated configuration of filters to monitor production network traffic

Embodiments of the present disclosure include techniques for discovering services across networks based on a multicast domain name system (mDNS) protocol. An mDNS request for available services in a network is received from a client device. The client device belongs to a particular layer 2 (L2) domain. In response to receiving the mDNS request, a storage of the network device configured to store service records is queried to determine a set of available services. The set of available services is provided in a L2 domain different from the particular L2 domain. A response that includes the set of available services is generated. The response is sent to the client device.
