Grafana Cloud (Mimir)

Configure Robusta to use Grafana Cloud's managed Prometheus (Mimir) for querying metrics.

Prerequisites

  • A Grafana Cloud account with a configured instance

  • Prometheus datasource configured in Grafana Cloud

  • Access to create service accounts and API tokens

Quick Start

  1. Find Your Grafana Instance URL:

    Log into your Grafana Cloud portal and note your instance URL (e.g., https://YOUR-INSTANCE.grafana.net).

  2. Create API Token:

    • Go to Administration → Service accounts

    • Create a new service account named "robusta-integration"

    • Generate a service account token

    • Save the token (starts with glsa_)

  3. Find Datasource UID:

    Using the Grafana API, list your datasources:

    curl -H "Authorization: Bearer YOUR_GLSA_TOKEN" \
  "https://YOUR-INSTANCE.grafana.net/api/datasources" | jq

    Note the UID for your Prometheus datasource (typically grafanacloud-prom).

  4. Find Your Cluster Name (if using multi-cluster setup):

    • Go to Grafana → Explore

    • Run query: up{cluster!=""}

    • Note the cluster label value

  5. Add to your generated_values.yaml:

    globalConfig:
    # Grafana Cloud Prometheus Configuration (via proxy)
    prometheus_url: https://YOUR-INSTANCE.grafana.net/api/datasources/proxy/uid/PROMETHEUS_DATASOURCE_UID
    prometheus_auth: Bearer YOUR_GLSA_TOKEN

    # Grafana API Key for enrichments and silencing
    grafana_api_key: YOUR_GLSA_TOKEN
    grafana_url: https://YOUR-INSTANCE.grafana.net

    # Grafana Cloud AlertManager Configuration
    alertmanager_url: https://YOUR-INSTANCE.grafana.net
    alertmanager_flavor: grafana
    alertmanager_auth: Bearer YOUR_GLSA_TOKEN

# Cluster identification (required for multi-cluster)
clusterName: YOUR_CLUSTER_NAME

    Note

    Optional: To create silences from Robusta, the Grafana API key must have the Editor role.

  6. Update Robusta

Multi-cluster Setup

Make sure clusterName in Robusta Helm's values matches the cluster label in Grafana.

clusterName: "production-us-east"
