T4K Integration with Observability Stack
The Observability Stack is a pre-packaged distribution for monitoring, logging and dashboard interfaces which can be installed into any existing Kubernetes cluster.
The Observability Stack is a pre-packaged distribution for monitoring, logging, and dashboarding and can be installed into any existing Kubernetes cluster. It includes many of the most popular open-source observability tools with Prometheus, Grafana, Promtail**,** and Loki. The observability stack provides a straightforward, maintainable solution for analyzing server traffic and identifying potential deployment problems.
To install the operator with observability enabled, run the latest helm chart with the following parameter set.
helm repo add triliovault-operator https://charts.k8strilio.net/trilio-stable/k8s-triliovault-operator
helm install tvm triliovault-operator/k8s-triliovault-operator --set observability.enabled=true
