Red Hat Enterprise Linux

Overview

The Red Hat Enterprise Linux (RHEL) integration in Motadata AIOps provides comprehensive monitoring capabilities for RHEL-based systems. By capturing and analyzing critical performance data, system logs, and metrics from RHEL devices and servers, this integration offers valuable insights into the health and performance of the RHEL infrastructure. With real-time visibility, administrators can proactively detect and resolve potential issues, optimize resource allocation, and ensure the smooth and secure operation of their RHEL environment, promoting overall stability and productivity.

Prerequisites
