Analysis of Network Logs

# 32






Abstract

Analysis of network logs collected from network devices is presented. The objective is to understand and determine the important network events and infer the possible root causes of those network events. The volume of network data is very high and often it can be quite challenging to filter out only the key important messages. We have developed ML / NLP based techniques to extract the underlying statistical templates of the SYSLOG messages, and secondly identify anomalous patterns observed in the SYSLOG events which can be useful to recommend suitable remedial actions. The proposed solution is under evaluation by network operations.
