Summary of Changes

Hello @mayankpande88, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces significant new capabilities, including GPU monitoring and enhanced JVM profiling. It also improves the agent's compatibility and configurability through refined cgroup handling, container filtering options, support for additional cloud providers, and a more robust Prometheus remote write mechanism with data spooling. Various dependencies have also been updated.

Highlights

  • GPU Metrics Collection: Added support for collecting NVIDIA GPU usage, memory, temperature, and power metrics at both the node and process levels. This provides visibility into GPU resource consumption by individual containers.
  • Improved Cgroup Handling: Refactored cgroup detection and parsing logic to better support cgroup v1 and v2 in various environments, including handling different mount points and container runtimes like Docker, containerd, and crio, and recognizing reserved.slice.
  • Container Filtering: Introduced new flags (--container-allowlist, --container-denylist) to allow users to specify which containers the agent should monitor using regex patterns.
  • New Cloud Provider Metadata: Added detection and collection of instance metadata for Alibaba Cloud, Scaleway, and IBM Cloud, enhancing node information in these environments. Also allows overriding discovered metadata via flags.
  • JVM Perfmap Dumping: Implemented functionality to trigger perfmap dumps in JVM processes configured with -XX:+PreserveFramePointer, improving symbol resolution for Java profiling.
  • Prometheus Remote Write Spooling: Added an on-disk spool for metrics data sent via Prometheus remote write, ensuring data is buffered and not lost during temporary network or endpoint unavailability.
  • Enhanced Network Metrics: Added source and destination region and availability zone labels to network bytes sent/received metrics, providing better geographical context for network traffic analysis.
  • Expanded Application Detection: Improved application type detection by adding recognition for Coroot components, OpenSearch, Ollama, VictoriaMetrics, VictoriaLogs, and Ruby, using both command line and executable path analysis.
