# How to ingest metrics from a Vector instance

Observability supports receiving data in the Prometheus `remote_write` format. To start sending metrics from a [Vector](https://vector.dev/docs/) instance, set up a [sink](https://vector.dev/docs/reference/configuration/sinks/prometheus_remote_write/) of the `prometheus_remote_write` type.

## Prerequisites

1. [Install](/cli/install) and [configure](/cli/configure) Nebius AI Cloud CLI.

2. If you don’t have a service account for observability services, [create one](/iam/service-accounts/manage).

3. Make sure that the service account is in a [group](/iam/authorization/groups) that has at least the `editor` role within your tenant; for example, the default `editors` group. You can check this in the [Administration → IAM](https://console.nebius.com/iam/service-accounts) section of the web console.

   If the service account is not in the required group, click <Icon icon="https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/button-vellipsis.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=e80b8e57c43bfd117679262e6a1334ad" width="12" height="24" data-path="_assets/button-vellipsis.svg" /> → **Add to group**, and select `editors`.

4. Issue a [static key](/iam/authorization/static-keys) for the service account using the following command:

   ```bash theme={null}
   nebius iam static-key issue \
     --name <name_for_the_key> \
     --account-service-account-id <service_account_ID> \
     --service observability
   ```

   Copy the value of the static key from the `token` parameter of the response. You will need it later in the configuration steps.

## How to configure a sink

1. Add the following `remote_write` section to the Vector configuration file:

   ```yaml theme={null}
   # Gather metrics from sources (for example, Vector's metrics from Vector itself)
   sources:
     vector_metrics:
       type: "internal_metrics"
       scrape_interval_secs: 15
       
   # Optional transformations

   # Send metrics to Observability via remote_write
   sinks:
     prometheus_remote_write:
       type: "prometheus_remote_write"
       inputs:
         - "vector_metrics"
       endpoint: "https://write.monitoring.<region_ID>.nebius.cloud/projects/<project_ID>/prometheus/api/v1/write"
       auth:
         strategy: "bearer"
         token: "<token_value>"
       healthcheck:
         enabled: false
   ```

   In this configuration, specify the following values:

   * Region ID from the [region list](../../../overview/regions).
   * [Project ID](/iam/manage-projects#how-to-get-a-project-id).
   * Token value of the static key that you [got earlier](#prerequisites).

2. [Restart or reload your Vector instance](https://vector.dev/docs/administration/management/).

Now, your Vector instance sends metrics to Observability Metrics.
