Learn Graylog with online courses and programs

Features of Graylog 

Graylog’s platform makes it easy for users to find data with customizable search workflows and dashboards that organizations can modify to meet their unique needs. It also features real-time monitoring, which generates alerts for abnormal behavior. The platform generates an alert whenever it detects an anomaly, enabling faster response times and preventing problems from escalating. Graylog offers three platforms, each one with a different focus:

• Graylog Operations: Graylog’s log management tool is designed to help IT and DevOps professionals gain better visibility into their systems. Graylog Open is the free, unlicensed version of Graylog Operations.

• Graylog Security: Graylog Security combines log management with a security information and event management (SIEM) tool that gives IT teams expanded cybersecurity capabilities.

• Graylog Open: Graylog Open is Graylog’s free, open-sourced version of their log management tool. It’s intended for smaller businesses and can process a maximum of 2GB of data per day.
