Abstract
Determining root causes of network issues includes identifying a previous network issue, comparing a first behavior of network components during the previous network issue with a second behavior of the network components during a current issue of a network, and obtaining a previous user input about a previous root cause of the previous network issue collected while diagnosing the previous issue.
Claims16
A computer program product for determining root causes of network issues, comprising:
- a non-transitory computer readable storage medium, said non-transitory computer readable storage medium comprising computer readable program code embodied therewith, said computer readable program code comprising code that, when executed, causes a processor to:
- identify a previous network issue;
- compare a first behavior of network components during said previous network issue with a second behavior of said network components during a current issue of a network;
- obtain a previous user input about a previous root cause of said previous network issue collected while diagnosing said previous network issue,
- assign a similarity score to said previous network issue relating to said current issue, the similarity score defined as a scalar value that represents the similarity between the current issue and previous network issue, the scalar value is a function of similarity S defined by:
- S(A1,A2)=[s,f,w]
- wherein Al and A2 are anomalies,
- wherein s is the similarity score,
- wherein f is a network component mapping function, and
- wherein w is a network component similarity strength between network issue components.
A system for determining root causes of network issues, comprising:
- a processor and a memory, wherein said memory stores program instructions that when executed, cause said processor to:
- identify a number of previous network issues of a network;
- compare a first behavior of network components during said previous network issues with a second behavior of said network components during a current network issue to discover similarities between said previous network issues and said current network issue;
- obtain a previous user input about a previous root cause of said previous network issues;
- rank said previous network issues in a ranking of a plurality of other previous network issues;
- determine a predicted current root cause based on said ranking;
- and
- obtain a current user input about whether said predicted root cause is accurate.
A method for determining root causes of network issues, comprising:
- comparing a first behavior of network components during a previous network issue with a second behavior of said network components during a current network issue;
- obtaining a previous user input about a previous root cause of said previous network issue;
- assigning a similarity score to said previous network issue in relation to said current network issue;
- determining a predicted current root cause based on said similarity score and previous network issue;
- and
- obtaining a current user input about whether said predicted root cause is accurate.
