Enhancements

Improved Monitoring for Horizontal Pod Autoscalers

Added kube_hpa_status_condition metric to provide visibility into the status conditions of Kubernetes Horizontal Pod Autoscalers (HPA). This helps you to track scaling decisions and overall HPA health.

New Configuration Option for Remote Filesystem Statistics

The new configuration option in the Linux Agent: remotefs_stats.enabled controls whether filesystem operation and traffic statistics are collected for each mount entry. By default, it is set to true. Additionally, the Agent now limits the collection of these statistics exclusively to remote mount points, ensuring more targeted data reporting.

Collector Connection Configuration Added to Host Shield

You can now specify the connection information for the Sysdig collector in the host-shield.yaml file as follows:

sysdig_endpoint:
  collector:
    host: <host>
    port: <port>

Vulnerability Fixes

This release addresses the following security vulnerabilities:

Defect fixes

  • Fixed an issue where compiling the kernel module failed on recent distributions, such as Fedora 40, which uses GCC 14.
