Tobs has been discontinued and is deprecated.
The code in this repository is no longer maintained.
Tobs is a tool that aims to make it as easy as possible to install a full observability stack into a Kubernetes cluster. Currently this stack includes:
- Kube-Prometheus the Kubernetes monitoring stack
- Prometheus to collect metrics
- AlertManager to fire the alerts
- Grafana to visualize what's going on
- Node-Exporter to export metrics from the nodes
- Kube-State-Metrics to get metrics from kubernetes api-server
- Prometheus-Operator to manage the life-cycle of Prometheus and AlertManager custom resource definitions (CRDs)
- Promscale (design doc) to store metrics for the long-term and allow analysis with both PromQL and SQL.
- TimescaleDB for long term storage of metrics and provides ability to query metrics data using SQL.
- Postgres-Exporter to get metrics from PostgreSQL server
- Opentelemetry-Operator to manage the lifecycle of OpenTelemetryCollector Custom Resource Definition (CRDs)
We plan to expand this stack over time and welcome contributions.
Tobs provides a helm chart to make deployment and operations easier. It can be used directly or as a sub-chart for other projects.
Using tobs to install full observability stack with openTelemetry support currently requires installation of cert-manager. To do install it please follow cert-manager documentation.
Note: cert-manager is not required when using tobs with opentelemetry support disabled.
The following command will install Kube-Prometheus, OpenTelemetry Operator, TimescaleDB, and Promscale into your Kubernetes cluster:
helm repo add timescale https://charts.timescale.com/
helm repo update
helm install --wait <release_name> timescale/tobs
Note: --wait flag is necessary for successfull installation as tobs helm chart can create opentelemetry Custom Resources only after opentelemetry-operator is up and running. This flag can be omitted when using tobs without opentelemetry support.
For detailed configuration and usage instructions, take a look at the helm chart's README.
All configuration for all components happens through the helm values.yaml file. You can view the self-documenting default values.yaml in the repo. We also have additional documentation about individual configuration settings in our Helm chart docs.
