# Install Monitoring Stack

## Overview

This page explains how to upgrade monitoring services in a Kubernetes cluster—Grafana for dashboards, Loki for logs, and Prometheus for metrics and alerts. It walks you through the upgrade steps using Helmfile and the required configurations.

## Prerequisites <a href="#prerequisites" id="prerequisites"></a>

Before proceeding with the upgrade, ensure you have the following tools installed and configured:

* **Helmfile**: A declarative spec for deploying Helm charts, which manages and deploys Helm releases via a simple, unified YAML file. [Installing Helmfile](https://helmfile.readthedocs.io/en/latest/#installation)
* **Helm**: A package manager for Kubernetes, used to define, install, and upgrade complex Kubernetes applications. [Installing Helm](https://helm.sh/docs/intro/install/)
* **kubectl**: A command-line tool for interacting with a Kubernetes cluster, allowing you to deploy applications, manage cluster resources, and view logs. [Installing Kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digit.org/health/v2.0/deploy/installation/production-setup/install-monitoring-stack.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
