Why

The changes introduce enhancements to the observability framework, focusing on metrics collection and service discovery. The addition of process-exporter configuration and script for dynamic service discovery (sd-bridge.sh) aims to improve monitoring of containerized applications, enabling better performance insights and container management.

What

• framework/observability/compose/conf/process-exporter.yaml
  • Added a new configuration file for process-exporter to define how processes are named and matched.
• framework/observability/compose/conf/prometheus.yml
  • Introduced metric_relabel_configs for the cadvisor job to extract container IDs from various runtime formats.
  • Added a new job process_exporter with metric_relabel_configs to extract container IDs from the group name and adjust labels for better container identification.
  • Included a container-sd job with file_sd_configs, enhancing service discovery through file-based configurations.
• framework/observability/compose/docker-compose.yaml
  • Added process-exporter service configuration, specifying image, container name, volumes, and commands for process metrics collection.
  • Introduced sd-bridge service for dynamic service discovery, including image, command, volumes, and environment variables configuration.
  • Included sd-targets volume to facilitate dynamic service discovery.
• framework/observability/compose/scripts/sd-bridge.sh
  • Added a new script sd-bridge.sh for dynamic service discovery, capable of discovering Docker containers by label, pulling discovery JSON, merging, de-duplicating, and writing Prometheus file_sd JSON.
