Abstract: An inference-oriented method for application flow and index vectorization includes: S1: quantizing original index information of related devices with known network flows and current flows in a distributed system into tuples of a same type to obtain known network flow information tuples and index information tuples; S2: quantizing unknown network flows into tuples of a same type to obtain unknown network flow information tuples; S3: forming a network according to a time window and a priori association relationship based on the known network flow information tuples, the index information tuples, and the unknown network flow information tuples, and sampling network description information by means of random walk; S4: obtaining network flow vectors and index information vectors by means of an embedding algorithm based on the network description information; and S5: performing root cause analysis and index prediction according to the network flow vectors and the index information vectors.

Abstract: The present invention provides a system and method for quickly determining a reasonable alarm threshold of a network, including: a presentation component for setting the template type and template parameter of an alarm simulation template, a generator for generating an alarm simulation task according to the alarm simulation template, a task component for executing the alarm simulation task to generate a data result set, and a storage component for storing and providing the data result set for the presentation component. The present invention adopts the asynchronous calculation, and adopts fragment manner during data statistics; the time period is divided into time slices and processed in parallel, and then aggregated, to improve the data processing rate; the similar alarm points are merged, thereby accurately obtaining the actual number of alarms and presenting in an incremental mode.

Abstract: A method and system for discovering and presenting access information of network applications includes: collecting access information between IP endpoints from a network packet collection; generating network diagrams; determining whether application component information needs to be configured, if yes, configuring application components, while if no, outputting the network diagrams; mapping the configuration information of the application components to the access information between the IP endpoints to obtain the access information based on the application components; updating the network diagrams according to the access information based on the application components; and outputting the network diagrams.
