Abstract: A method of classifying a sample of values related to the use of a server, including: recording, by the server, use events in a log; configuring a classifier tool with a behavioral model formed of a weighted list of parameters, establishing a sample of values from the log, and supplying it to a classifier tool, which calculates a score representative of the adequacy of the sample to a target category, reading recent use events saved in the log and aggregating them over basic time intervals, storing the aggregation result obtained for each basic interval in a distinct record of a first group; aggregating, when the number of records of the first group reaches a threshold, the contents of the records of the first group in a distinct record of a second group, and establishing the sample from the contents of records of the database.

Abstract: A method of classifying a sample of values related to the use of a server, comprises the steps of recording, by the server, use events in a log; configuring a classifier tool with a behavioral model formed of a weighted list of parameters; establishing the sample of values from the log and supplying it as parameters to a classifier tool, whereby the classifier tool calculates a score representative of the adequacy of the sample to a target category; reading recent use events saved in the log and aggregating them over basic time intervals; storing in a database the aggregation result obtained for each basic interval in a distinct record of a first group; aggregating, when the number of records of the first group reaches a threshold, the contents of the records of the first group in a distinct record of a second group of the database; and establishing the sample of values supplied to the classifier tool from the contents of records of the database.
