Abstract
A network monitor that segments data packets at variable locations of data packets and stores a subset of the segments for troubleshooting or analysis. The network monitor selects data packets to be stored based on a set of user-defined classifier rules and discards other data packets. Each data packets selected for storage are analyzed up to an application protocol layer to determine start locations and/or end locations of data fields in the data packet. A set of user-defined slice rules are applied to each analyzed data packets to segment the data packets at the determined locations of the data fields. A subset of the data packet segments is stored in the network monitor. By storing relevant portions of data packets and discarding other portions of the data packets, the amount of data of data to be stored in the network monitor can be significantly reduced.
