# Set up ingestion from an existing Prometheus server in Kubernetes on Fargate
<a name="AMP-onboard-ingest-metrics-existing-Prometheus-fargate"></a>

Amazon Managed Service for Prometheus supports ingesting metrics from Prometheus servers in self-managed Kubernetes clusters running on Fargate. To ingest metrics from Prometheus servers in Amazon EKS clusters running on Fargate, override the default configs in a config file named amp\_ingest\_override\_values.yaml as follows:

```
prometheus-node-exporter:
  enabled: false

alertmanager:
  enabled: false

serviceAccounts:
  server:
    name: amp-iamproxy-ingest-service-account
    annotations: 
      eks.amazonaws.com/role-arn: ${IAM_PROXY_PROMETHEUS_ROLE_ARN}

server:
  persistentVolume:
    enabled: false
  remoteWrite:
    - url: https://aps-workspaces.${REGION}.amazonaws.com/workspaces/${WORKSPACE_ID}/api/v1/remote_write
      sigv4:
        region: ${REGION}
      queue_config:
        max_samples_per_send: 1000
        max_shards: 200
        capacity: 2500
```

Install Prometheus using the overrides with the following command:

```
helm install prometheus-for-amp prometheus-community/prometheus \
                   -n prometheus \
                   -f amp_ingest_override_values.yaml
```

Note that in the Helm chart configuration we disabled the node exporter and the alert manager as well as running the Prometheus server deployment.

You can verify the install with the following example test query.

```
$ awscurl --region {{region}} --service aps "https://aps-workspaces.{{region_id}}.amazonaws.com/workspaces/{{workspace_id}}/api/v1/query?query=prometheus_api_remote_read_queries"
Output:
    {"status":"success","data":{"resultType":"vector","result":[{"metric":{"__name__":"prometheus_api_remote_read_queries","instance":"localhost:9090","job":"prometheus"},"value":[1648461236.419,"0"]}]}}21
```
