摘要:
Methods, systems, and products infer performance of a domain name system. Queries to, and responses from, the domain name system are logged and categorized. Each category is associated with a different performance issue related to the domain name system. The number of entries in each category may be used to infer the performance of the domain name system.
摘要:
A technique for monitoring performance in a network uses passively monitored traffic data at the server access routers. The technique aggregates performance metrics into clusters according to a spatial hierarchy in the network, and then aggregates performance metrics within spatial clusters to form time series of temporal bins. Representative values from the temporal bins are then analyzed using an enhanced Holt-Winters exponential smoothing algorithm.

Disclosed are thionated fused-ring (aromatic) imides and diimides that can exhibit desirable electronic properties and can possess processing advantages including solution-processability and/or good stability at ambient conditions.
摘要:
Example methods, apparatus and articles of manufacture to perform root cause analysis for network events are disclosed. An example method includes retrieving a symptom event instance from a normalized set of data sources based on a symptom event definition; generating a set of diagnostic events from the normalized set of data sources which potentially cause the symptom event instance, the diagnostic events being determined based on dependency rules; and analyzing the set of diagnostic events to select a root cause event based on root cause rules.
