Abstract: The present disclosure is directed to systems and methods of configuring a resource for network traffic analysis. An agent executed by a computing device receives an indication to record a browsing session. The agent records network activity data of the browsing session. The agent generates a data file with the recording. The agent transmits the data file and a request to generate a report to an analytics server. The analytics server receives the request and extracts the network activity data from the data file. The analytics server applies an event processing protocol to the network activity data. The analytics server generates a report and transmits the report to the client device for display.

Abstract: A data center includes various sets of infrastructure modules which each provide a particular type of infrastructure support to support computing operations in the data center.
