Red Hat Insights launches new recommendations to keep Application Streams running

Red Hat Developer Subscription for Individuals provides access to the most popular database and/or web servers, such as PostgreSQL, MariaDB, httpd and Nginx via Application Streams. While this is a great way for Linux developers to get started implementing applications quickly, Application Streams follow their own lifecycles, which can pose a challenge for RHEL developers and administrators trying to keep their system in a supported state.

Red Hat Insights to the rescue! We’ve recently added a new set of Advisor recommendations which alerts users for an approaching retirement date of Application Streams. 

Lifecycle alerts and other recommendations

Developers can use the Insights service to monitor and analyze Application Stream workloads, so they can be confident that they're running smoothly at all times. The platform monitors your environment and produces recommendations when it detects problems or unexpected behavior.

Let’s take Nginx as an example. Recommendations in Red Hat Insights will help you:

• Prevent performance and availability issues

  • Nginx performance can be improved when pinning Nginx worker processes to individual CPUs 

  • The Nginx server is unsafe and not connectable because the SSL certificate has expired 

• Remediate security issues and CVEs in your environment:

  • Decreased security: Nginx crypto-policies overridden 

  • Decreased security: Nginx using deprecated TLSv1.1 protocol 

• Make sure you are running a fully maintained and supported Application Stream

  • Red Hat has discontinued technical support services as well as software maintenance services for the End-Of-Life of Nginx 

Every recommendation comes with system-specific details about the detected issue, steps to resolve and a source of additional information.

Remediate issues via Red Hat connector tool

Insights findings, such as Advisor recommendations, typically come with an automated method for remediation. To apply the remediation, you can leverage the Red Hat connector (RHC) tool, whichallows users to execute provided remediations directly on their hosts from within the Red Hat Hybrid Cloud Console. 

To configure the Red Hat connector, you need to follow a few simple steps outlined in the Red Hat connector Configuration Guide.
