Abstract: In the disclosed embodiments, a remote capture agent monitors network packets traversing a network interface of a computing device in an information technology environment. Network data is obtained from the network packets. The network data is modified based on configuration information obtained by the remote capture agent from a configuration server to obtain modified network data. Timestamped events are generated based on the modified network data, and the timestamped events are sent to another component on the network for subsequent processing.

Abstract: The disclosed embodiments provide a system for extracting custom content from network packets. During operation, the system receives a stream of packets. The system then parses packets in the stream to determine a protocol for each packet. Next, the system applies a custom-content-extraction rule to each packet associated with a target protocol to obtain the extracted content. Then, the system stores the extracted content in events in a data store to facilitate subsequent queries involving the extracted content.

Abstract: The disclosed embodiments provide a system that processes network data. During operation, the system obtains, at a remote capture agent, a first protocol classification for a first packet flow captured by the remote capture agent. Next, the system uses configuration information associated with the first protocol classification to build a first event stream from the first packet flow at the remote capture agent, wherein the first event stream comprises time-series event data generated from network packets in the first packet flow based on the first protocol classification. The system then transmits the first event stream over a network for subsequent storage and processing of the first event stream by one or more components on the network.

Abstract: The disclosed embodiments provide a system that facilitates the processing of network data. During operation, the system causes for display, on a computer system, a graphical user interface (GUI) for obtaining configuration information for configuring the generation of time-series event data from network packets captured by one or more remote capture agents. Next, the system causes for display, in the GUI, a first set of user-interface elements for managing one or more ephemeral event streams that contain temporarily generated time-series event data from the network packets, wherein managing the one or more ephemeral event streams comprises modifying an end time for terminating the capture of time-series event data in an ephemeral event stream. The system then updates the configuration information based on input received through the first set of user-interface elements.
