Red Hat Enterprise Linux (RHEL) 8.2 brings new features that include expanded monitoring capabilities in Red Hat Insights for and new container tools, including containerized versions of Skopeo and Buildah.

Red Hat says RHEL 8.2 is arriving at a time when, because of the Covid-19 pandemic, a growing percentage of IT staffers are working remotely. Their ability to support the management and monitoring of operations and their ability to detect and address problems has never been more critical, and upgrades to Red Hat Insights are designed to help.

Red Hat Insights

Red Hat Insights, is Red Hat’s operations and security-risk-management offering and helps detect, diagnose and remediate potential problems before they affect production systems or end users. It was included in RHEL in May 2019.

The latest updates include:

  • Improved visibility and  security for managing large, complex environments
  • Policy and patch services to help determine which product advisories apply and guidance for problem remediation
  • A "drift service" to make it easier to compare baselines, shape strategies that reduce complexity, and make troubleshooting easier

Monitoring and performance updates

RHEL 8.2 brings some performance upgrades includeing:

  • Improved resource management with Control Groups (cgroup) v2, which is designed to reserve and set limits on memory usage to help prevent processes from overconsuming memory and causing system failures or slowdowns.
  • Optimizing performance-sensitive workloads via NUMA and sub-NUMA service policies.
  • Performance Co-Pilot (PCP) 5.0.2 which adds collection agents for Microsoft SQL Server 2019 to gather and analyze SQL Server metrics to draw a clearer picture of database and operating-system performance.
  • Red Hat subscription watch,a service for viewing and managing RHEL and Red Hat OpenShift Container Platform subscriptions.
