Prometheus Agent Remote Write Config :: Kloudfuse Docs

Prometheus Agent Remote Write Config

Using an Existing Prometheus Server

Determine the ingress IP for the Kloudfuse stack.

   kubectl get svc | grep kfuse-ingress-nginx-controller

Copied!

You can use either the EXTERNAL-IP address, or DNS name.


	DNS name does not work if the Kloudfuse stack is on a different VPC or cluster than the target cluster. You can use the IP address in all circumstances.

Add a remote_write endpoint to use the Prometheus server. Choose the correct option, depending on your network protocol (http or https):

   http://<REPLACE KFUSE ADDRESS>/write as the remote_write

https://<REPLACE KFUSE ADDRESS>/write as the remote_write

Copied!

If the Prometheus server is installed using the standalone Prometheus helm chart, add the following helm values and run helm upgrade:

   serverFiles:
        prometheus.yml:
          remote_write:
         - url: http://<REPLACE KFUSE ADDRESS>/write
           queue_config:
             max_samples_per_send: 4000

Prometheus Operator

Helm Chart Values

Use these steps if the Prometheus server is installed using Prometheus Operator or kube-prometheus-stack helm chart:

Add the following helm values:

   prometheus:
        remoteWrite:
       - queueConfig:
           maxSamplesPerSend: 4000
         url: http://<REPLACE KFUSE ADDRESS>/write

Copied!

Run helm upgrade.

Prometheus CRD

Alternatively, configure the remote write through Prometheus CRD.

Update the Prometheus CRD (kind: Prometheus) using the following remoteWrite entry:

   remoteWrite:
     - queueConfig:
         maxSamplesPerSend: 4000
       url: http://<REPLACE KFUSE ADDRESS>/write

Replacing the Prometheus Server

You can also replace the Prometheus server with Grafana Agent, which is lighter-weight and can be configured to scrape and emit write metrics.

Use the following helm chart to install the agent. Use the following helm values:

   config:
     prometheus:
       remoteWrite:
         url: http://<REPLACE KfUSE ADDRESS>/write
       configs:
         <copy existing scrape configs here>
