At a high level, this release contains

• Swapped Prometheus and Grafana helm charts with Kube-Prometheus helm chart.
• Option to enable Prometheus and Promscale high availability with --enable-prometheus-ha.
• Rich Kubernetes specific Grafana dashboards from Kube-Prometheus i.e. Kubernetes Mixins.
• Added a tobs command to display version i.e.
  tobs version (for CLI version & latest tobs helm chart version) or tobs version -d (for CLI version & deployed tobs helm chart version).

Details

• In this release, we swapped the Prometheus & Grafana deployments with Kube-Prometheus to provide one shop monitoring experience with Kube-Prometheus it comes with Prometheus-Operator to manage the life-cycle of Prometheus and AlertManager instances with dedicated custom resource definitions (CRDs) to manage Prometheus configuration.
• Tobs offers all the rich dashboards offered by Kube-Prometheus alongside aggregated cluster and hardware monitoring dashboards that offered by tobs in the previous versions.
• Option to enable Prometheus, Promscale high-availability in tobs using the flag --enable-prometheus-ha during the installation. If you are using tobs helm chart (without tobs CLI), please follow the HA guide.

Note:

• tobs upgrade command will upgrade all the existing tobs installations to the new 0.4.0 version.
• If you are using tobs helm chart (without tobs CLI), please follow the upgrade guide.

Thanks 🙏

• @gouthamve @lilic @bwplotka @paulfantom for proposing to vendor Kube-Prometheus as monitoring stack in tobs.
