摘要: Network performance data is collected, recorded, and normalized. In one embodiment, a set of first performance data collected by an agent in response to network transactions initiated by the agent and a second set of performance data resulting from passively monitoring traffic on the network are received. The first and second sets of performance data are normalized to create a set of constantly formatted network performance data capable of convenient analysis.

摘要: 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.

摘要: A network monitoring system that summarizes a plurality of data packets of a session into a compact session record for storage and processing. Each session record may be produced in real-time and made available during the session and/or after the termination of the session. Depending on protocols, a network monitoring system extracts different sets of information, removes redundant information from the plurality of data packets, and adds performance information to produce the session record. The network monitoring system may retrieve and process a single session record or multiple session records for the same or different protocols to determine cause of events, resolve issues in a network or evaluate network performance or conditions. The session record enables analysis in the units of session instead of individual packets. Hence, the network monitoring system can analyze events, issues or performance of the network more efficiently and effectively.
