Monitoring Docker, OpenShift, Kubernetes and Linux - Version 5.23

October 23, 2024

Version 5.23 of our applications, configurations, and Collectord are now available. In this blog post, we will cover some highlights of the release.

Support for large clusters

This release was focused on improving the performance and scalability of our monitoring solutions, particularly for large Kubernetes and OpenShift clusters. We have optimized and rewrote the Watch requests implementation for the Kubernetes API Server. You can keep using old implementation if the configuration keeps unchanged, or you can change it with watchImplementation=2 under [general.kubernetes] (default value).

To better support installations with large number of nodes and containers, default behavior for most of the dashboards is to require pressing a Submit button after selecting filters.

Pod and Node Status Monitoring

Across dashboards, we have added statuses and conditions of Nodes and Pods. For example, the Overview dashboard will show you a list of Not Ready Containers running in your cluster, so you can quickly identify the issues.

Other significant changes

  • Allow defining outputs for Prometheus metrics defined with annotations.
  • Improving for the Audit Dashboards to include user agents, and slightly improve performance for the new installations.
