• Comments on the design from Tech Call
  • Suggested to add pushgateway and alertmanager installation as part of the installation of the whole Prometheus stack, and remove if from install_ngsa.sh
  • Suggested to embed the helm chart as a dependency
  • Evaluate the complexity of using the same stack for the monitoring of OSM platform (--k8s_monitor option in the installer)
  • Make sure that the configuration done by the init-container in current installation is kept.
  • Make sure that the sidecar introduced by OSM is kept.
