Claim One:
1. 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 ( A 1 ,A 2 )=[ s,f,w] wherein A l and A 2 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.
