Abstract: A method performed by a monitoring tool in a computer system, the method including: for a set of network nodes in a computer system: applying a correlation formula on an input based on performance data of the set, and determining a correlation score based on applying the correlation formula, the correlation score indicating a correlation between network nodes in the set; determining, based on the correlation scores, a first list including a first plurality of network nodes having a correlation score that satisfies a first threshold; identifying a second plurality of network nodes included in the first list, the second plurality of network nodes having a correlation score that satisfies a second threshold, which indicates a correlation that is higher than the first threshold; analyzing the performance data of the second plurality against a constancy metric; and removing, based on the analyzing, the second plurality from the first list.

Abstract: A technique for use in controlling routing of a call in a communications system is provided. In one embodiment of the technique, a call routing script is used. The script includes at least one call routing instruction that refers to a variable whose value is stored externally to the script. The value of the variable is determined by the system when the system executes the script for determining a destination for the call. The value of the variable is stored in a database, and the database is read to determine the value of the variable.

Abstract: Techniques are provided for use in generating call routing control scripts. The techniques permit call routing control scripts, initially generated for use in controlling a first communication system, to be adapted for use in controlling a second, different communication system. More specifically, in these techniques, values (e.g., numerical values) used to identify script-controlled objects (i.e., physical or logical entities in the first system) in the initially-generated script, are replaced with values identifying equivalent objects in the second system, to thereby facilitate creation of another script that is executable by the second system. The initially-generated script contains a section in which the object identification values used in the initially-generated script are grouped together, in association with respective logical handles/names and respective object classifications of the objects that they identify, in order to facilitate determination of the equivalent objects.

Abstract: A technique for use in controlling the routing of a call in a communications system is provided. In one embodiment of the technique, a call routing script is generated. The script includes at least one call routing instruction of a predetermined type that refers to a variable whose value is stored externally to the script. The value of the variable is determined by the system when the system executes the script for use in determining a destination of the call.
