1. A system comprising: a non-transitory memory storing machine readable instructions for: a text classifier, a datafield classifier, a metadata classifier, and a combination classifier; and a processor communicatively coupled to the memory, the processor executing the machine-readable instructions to: identify, according to a log format rule, a log description of a log entry and a metafield of the log entry, the identifying performed using the text analyzer, determine that the log description comprises a datafield based on a comparison of the log description with datafield indicators of a word model, the determining performed using the text classifier, generate datafield metrics for the datafield, the datafield metrics corresponding to categorical identifiers, the datafield metrics indicating an accuracy of a datafield categorization, the datafield categorization including an association between the datafield and a corresponding categorical identifier, and the generating performed using the datafield classifier, generate metadata metrics for the metafield, the metadata metrics corresponding to the categorical identifiers, the metadata metrics indicating an accuracy of a metafield categorization, the metafield categorization including an association between the metafield and the corresponding categorical identifier, and the generating performed using the metadata classifier, apply weight values to the datafield metrics and the metadata metrics, the applying performed using the combination classifier generate weighted metrics for the log entry, the weighted metrics including an accuracy indication of a log categorization, the log categorization including an association between the log entry and the corresponding categorical identifier, and the generating performed using the combination classifier, and generate a mapping between a categorical identifier of the categorical identifiers and the log entry in response to at least one of the weighted metrics for the log entry exceeding a predefined threshold, the generating performed using the combination classifier.
