Grafana Loki

Grafana Loki is a horizontally scalable, highly available, multi-tenant log aggregation system. It supports a wide range of log formats, sources, and clients, and allows formatting logs at query time rather than at ingestion. Loki only indexes the metadata of a log line which significantly reduces space required to store logs and makes working with them simpler and faster. Integrations with Prometheus, Grafana, and Kubernetes are supported natively, providing a one-stop-shop UI for metrics, logs, and traces.

You can deploy Grafana Loki in your Nebius AI Managed Service for Kubernetes clusters using this Marketplace product.

Before installing this product:

1. Configure storage:

   1. If you don’t have the Nebius AI command line interface yet, install and initialize it.

   2. Create a service account and assign the storage.uploader and storage.viewer roles to it.

   3. Create a static access key for the service account and save it as JSON:

      ncp iam access-key create \
        --service-account-name <service_account_name> \
        --format json \
      > sa-key.json
      

   4. Create an Object Storage bucket.

2. Create a Kubernetes cluster and a node group in it, install kubectl, and configure it to work with the created cluster.

To install the product:

1. On the cluster page in the management console, go to the Marketplace tab, select the product, and click Install.

2. Configure the application:

   • Namespace: Select a namespace or create a new one.
   • Application name: Enter an application name.
   • Bucket name: Enter the bucket name.
   • Static access key: Paste the contents of the access key JSON file.
