You can also trace software installations and data transfers to identify potential issues in real time rather than after the damage is done. Those logs also go a long way towards keeping your company in compliance with the General Data Protection Regulation GDPR that applies to any entity operating within the European Union.

If you have a website that is viewable in the EU, you qualify. Logging—both tracking and analysis—should be a fundamental process in any monitoring infrastructure.

A transaction log file is necessary to recover a SQL server database from disaster. Further, by tracking log files, DevOps teams and database administrators DBAs can maintain optimum database performance or find evidence of unauthorized activity in the case of a cyber attack.

For this reason, it's important to regularly monitor and analyze system logs. It's a reliable way to re-create the chain of events that led up to whatever problem has arisen.

Graylog can balance loads across a network of backend servers and handle several terabytes of log data each day. IT administrators will find Graylog's frontend interface to be easy to use and robust in its functionality. Graylog is built around the concept of dashboards, which allows you to choose which metrics or data sources you find most valuable and quickly see trends over time.

When a security or performance incident occurs, IT administrators want to be able to trace the symptoms to a root cause as fast as possible. Search functionality in Graylog makes this easy. It has built-in fault tolerance that can run multi-threaded searches so you can analyze several potential threats together. Nagios started with a single developer back in and has since evolved into one of the most reliable open source tools for managing log data.

Its primary product is a log server, which aims to simplify data collection and make information more accessible to system administrators. The Nagios log server engine will capture data in real-time and feed it into a powerful search tool.
