tobs - The Observability Stack for Kubernetes

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:

<img src="docs/assets/tobs-arch.png" alt="Tobs Architecture Diagram" width="800"/>

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.

Quick start

Prerequisites

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.

Installing the helm chart

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.

Configuring the stack

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.
