# T4K Integration with Observability Stack
## Introduction
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.
### T4K Installation with Observability using Trilio Operator
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
```
