Automatic creation of related event groups for an IT service monitoring system
The operation of an automatic service monitoring system (SMS) is directed by stored control information. Methods and mechanisms are provided to create control information that directs operations of the SMS regarding the grouping together of related notable events for unified display and processing. The control information directs grouping operations that automatically correlate the events without requiring, for example, a set of declarative grouping rules.
1. A method performed by one or more processing devices, the method comprising:
receiving a sample set of events from a service monitoring system (SMS);
iteratively generating a plurality of event group definitions at a current complexity level and incrementing the current complexity level, until a predefined terminating criterion is satisfied, wherein each event group definition of the plurality of event group definitions comprises a number of factors specified by the current complexity level, wherein each factor is represented by a respective fieldname-value pair of an event of the sample set of events; and
determining, based on the plurality of event group definitions, one or more event groups of a plurality of events.
2. The method of claim 1 , further comprising:
selectively excluding, from the plurality of event group definitions, event group definitions failing to satisfy a predefined event membership threshold.
3. The method of claim 1 , further comprising:
selectively excluding, from the plurality of event group definitions, event group definitions satisfying a predefined exclusion criterion.
4. The method of claim 1 , further comprising:
identifying, based on metadata associated with the sample set of events, a plurality of fieldnames for defining a respective plurality of factors.
5. The method of claim 1 , further comprising:
identifying, based on frequency of occurrence of fieldnames in the sample set of events, a plurality of fieldnames for defining a respective plurality of factors.
6. The method of claim 1 , further comprising:
selectively merging, based on predefined merge criterion, two or more event group definitions of the plurality of event group definitions.
7. The method of claim 1 , further comprising:
selectively merging, based on predefined merge criterion reflecting an event overlap threshold, two or more event group definitions of the plurality of event group definitions.
8. The method of claim 1 , further comprising:
iteratively traversing a plurality of event group definitions and decrementing the current complexity level, wherein each iteration comprises selectively excluding, from the plurality of event group definitions, event group definitions failing to satisfy a predefined event group promotion criterion.
9. The method of claim 1 , further comprising:
identifying permutations between a higher-level event group definitions and a first-level event group definitions that satisfy a permutation criterion; and
for each identified permutation creating a higher-level event group definition.
10. The method of claim 1 , further comprising:
identifying, based on a predefined permutation criterion reflecting a permutation size, permutations between a higher-level event group definitions and a first-level event group definitions that satisfy a permutation criterion; and
for each identified permutation creating a higher-level event group definition.
11. A system comprising:
a memory; and
a processing device coupled to the memory, the processing device to perform operations comprising:
receiving a sample set of events from a service monitoring system (SMS);
iteratively generating a plurality of event group definitions at a current complexity level and incrementing the current complexity level, until a predefined terminating criterion is satisfied, wherein each event group definition comprises a number of factors specified by the current complexity level, wherein each factor is represented by a respective fieldname-value pair of an event of the sample set of events; and
determining, based on the plurality of event group definitions, one or more event groups of a plurality of events.
12. The system of claim 11 , wherein the operations further comprise:
selectively excluding, from the plurality of event group definitions, event group definitions satisfying a predefined exclusion criterion.
13. The system of claim 11 , wherein the operations further comprise:

14. The system of claim 11 , wherein the operations further comprise:
selectively merging, based on predefined merge criterion, two or more event group definitions of the plurality of event group definitions.
15. The system of claim 11 , wherein the operations further comprise:
iteratively traversing a plurality of event group definitions and decrementing the current complexity level, wherein each iteration comprises selectively excluding, from the plurality of event group definitions, event group definitions failing to satisfy a predefined event group promotion criterion.
16. A non-transitory computer-readable storage medium comprising executable instructions that, when executed by one or more processing devices, cause the one or more processing devices to perform operations, comprising:
receiving a sample set of events from a service monitoring system (SMS);
iteratively generating a plurality of event group definitions at a current complexity level and incrementing the current complexity level, until a predefined terminating criterion is satisfied, wherein each event group definition comprises a number of factors specified by the current complexity level, wherein each factor is represented by a respective fieldname-value pair of an event of the sample set of events; and
determining, based on the plurality of event group definitions, one or more event groups of a plurality of events.
17. The non-transitory computer-readable storage medium of claim 16 , wherein the operations further comprise:
selectively excluding, from the plurality of event group definitions, event group definitions satisfying a predefined exclusion criterion.
