Claim Text:
1. A method for two stage log normalization, the method comprising: retrieving, by one or more computer processors, a message format and a plurality of parameters from one or more log files; determining, by one or more computer processors, a classification for one or more first sequence files, wherein the one or more first sequence files includes the message format from the one or more log files, wherein determining includes creating the one or more first sequence files, wherein creating includes retrieving a corresponding unique message identifier (ID) for each of the one or more log files, and utilizing conventional machine learning processes to train data for the classification of the one or more first sequence files; determining, by one or more computer processors, a classification of error for the one or more first sequence files by determining one or more similarities between the one or more first sequence files and a plurality of existing trained data; determining, by one or more computer processors, whether there is a high confidence in the classification of error for the one or more first sequence files by determining a level of similarity between the classification of error for the one or more first sequence files and the plurality of existing trained data; responsive to a determination that the level of similarity between the classification of error for the one or more first sequence files and the plurality of existing trained data is high, determining, by one or more computer processors, that there is a high confidence in the classification of error; responsive to a determination that the level of similarity between the classification of error for the one or more first sequence files and the plurality of existing trained data is low, determining, by one or more computer processors, that there is not a high confidence in the classification of error; responsive to a determination that there is not a high confidence in the classification of error for the one or more first sequence files, determining, by one or more computer processors, whether there is an improvement in confidence in the classification of error from one or more second sequence files, wherein the one or more second sequence files includes the message format and the plurality of parameters from the one or more log files, wherein determining the improvement includes creating the one or more second sequence files, wherein creating includes retrieving a corresponding unique parameter ID for each of the one or more log files and sequencing the unique message ID for each of the one or more log files with the respective unique parameter ID, re-classifying the one or more second sequence files, wherein re-classifying includes determining a classification of error for the one or more second sequence files, and determining a level of similarity between the classification of error for the one or more second sequence files and the plurality of existing trained data; responsive to a determination that the level of similarity between the classification of error for the one or more second sequence files and the plurality of existing trained data has improved over a level of similarity between a classification of error for the one or more first sequence files and the plurality of existing trained data, determining, by one or more computer processors, there is an improvement in confidence in the classification of error for the one or more second sequence files; and responsive to a determination that the level of similarity between the classification of error for the one or more second sequence files and the plurality of existing trained data has not improved over a level of similarity between a classification of error for the one or more first sequence files and the plurality of existing trained data, determining, by one or more computer processors, there is not an improvement in confidence in the classification of error for the one or more second sequence files.
