Techniques for parsing rule creation are provided. A technique for constructing one or more message parsing rules may comprise the following steps. First, message data representing past messages, for example, associated with a network, an application and/or a system being analyzed, is obtained. For example, this may involve reading the past or historical message data from messages logs or having a system point to the message data in existing data storage. Parsing rules are then generated by a process from one or more existing rule templates and/or based on user selection and classification of at least a portion of a message. For example, the user may choose a message part and demonstratively classify the part, for example, as a positive or negative example. The generated rules may then be stored for access by a rule-based parsing system such as a message adaptation system. Prior to generation of the one or more parsing rules, a message structure may be established upon which generation of the rules may be based.

Methods and apparatus for creation of parsing rules

A method and system for identifying relevant metrics among metrics that are measured to determine conformance with a service level agreement. The method includes selecting two sets of points, each set representing a given number of measurements for an individual metric and setting a separate threshold for each of the sets of points. The threshold values are selected to produce a set of quadrants so as to maximize distribution of points of intersection of each of the sets of points between a second quadrant and a fourth quadrant in a four-quadrant graph. The method can be performed on a computer system.

Identification of relevant metrics

A system and program product for generating throttling parameters for an information management (IT) system based on historical event log data. An embodiment of the system comprises: an identification system that examines the historical event log data and identifies throttling candidates, wherein each throttling candidate comprises an event type for redundant events that reoccur over at least one measured time period; and an analysis system that statistically analyzes event data associated with each throttling candidate and generates a set of throttling parameters for each throttling candidate based on the event data.

Techniques for data-driven validation, completion and construction of event relationship networks (ERNs) are provided. Event relationship networks are widely used in event management system design. To date, ERNs are constructed purely based on human expertise and there is no automatic or event semi-automatic method that validates or completes ERNs. The present invention provides techniques for automatically validating and completing existing ERNs and/or constructing new ERNs, based on collected event data.
