Enhancements

• Real-Time Metrics:

  • Automatic refresh every 2 seconds for up-to-date insights.

• Optimized Process View:

  • Top 20 processes sorted by CPU usage for quick and clear identification of resource-hungry tasks.

• Color-Coded Thresholds:

  • Instant visual cues for CPU and memory usage levels.

• Configurable Settings:

  • Metrics port and log file path derived from configuration:
    • Primary: /etc/hmac-file-server/config.toml
    • Fallback: ../config.toml
  • Sensible defaults if server.metricsport or server.logfile are not defined.

• Robust Fallback Logic:

  • Gracefully handles missing configuration values.
  • Terminates with a fatal error if no configuration file is found at all.

Known Limitations

• HMAC Dependency:

  • If hmac-file-server is not running, relevant metrics and information will be unavailable.

• Distribution:

  • The monitoring tool is included in the .deb package for the stable 2.5 release, ensuring streamlined installation and updates for users.
