ManageEngine EventLog Analyzer vs Nagios Log Server

  • This document provides a feature-wise comparison report between ManageEngine EventLog Analyzer and Nagios Log Server. Comparison done here is based on the information available in the competitor’s website and so the details may vary with the real product.
  • ManageEngine EventLog Analyzer is a comprehensive SIEM solution that helps you to automate log management, log collection, analysis, event correlation, threat intelligence, file integrity monitoring, log search and archiving to meet the compliance and SIEM needs of your complete network from a single console.
  • Nagios log server is capable of managing and monitoring logs which includes getting all log data in one location, with high availability and fail-over built right in. Servers can be quickly configured to send all log data with easy source setup wizards to start monitoring logs in minutes. The stored log data will index the content of the messages, and store the data for later retrieval or querying and analysis in near real-time.
  • Nagios log sever lacks certain advanced features like file integrity monitoring, threat intelligence, and incident management. It can help in meeting compliance policies through its archiving and clean-up features but does not provide exclusive compliance reports. Also, reports cannot be easily exported in the desired format nor can it be scheduled to be emailed to specific users. This is makes it tedious to look for reports if they are to be analyzed on a weekly or daily basis.
