This Post was updated in June of 2024 to remove the requirement to install VMAgent on each Proxmox VE node, and update the screenshots to reflect updates in VictoriaMetrics Cloud and Grafana.

Monitoring Proxmox VE via VictoriaMetrics CLoud

In this blog post we’re going to walk you through how to monitor Proxmox VE via VictoriaMetrics Cloud, including a step by step guide on how to setup, configure, and visualize this environment.

Proxmox VE is a complete, open-source server management platform for enterprise virtualization. It tightly integrates the KVM hypervisor, Linux Containers (LXC), software-defined storage, and, software defined networking in a single platform. All of these features can be managed via a web GUI, CLI, and infrastructure as code tools such as Ansible and Terraform. All of these interfaces support managing virtual machines, containers, high availability for clusters, and configuring disaster recovery.

VictoriaMetrics Cloud allows users to run VictoriaMetrics on AWS without the need to perform typical DevOps tasks such as proper configuration, monitoring, logs collection, access protection, software updates, backups, etc.

The guide covers:

• How to setup a deployment on VictoriaMetrics Cloud
• How to view data in VictoriaMetrics Cloud
• How to add VictoriaMetrics Cloud as a datasource in Grafana
• How to visualize data from VictoriaMetrics Cloud in Grafana

Preconditions:

• Proxmox VE version 7.0+
• Grafana 11.0+
• VictoriaMetrics Cloud account
• Installed Grafana
• Grafana dashboard for Proxmox VE

1. Setup VictoriaMetrics Cloud deployment #

If you don’t have the VictoriaMetrics Cloud account yet, just sign up here – it’s free.

To read more about VictoriaMetrics Cloud see the announcement blog post.

Open https://console.victoriametrics.cloud/deployments and click start sending metrics if you don’t already have an existing deployment.

Configure the deployment with parameters that best suit your case and click Create. For this demo I chose the starter instance, in the region closest to me with 13 months of retention.

New deployment creation

Once the deployment is created and provisioned, you will get an email notification. Click on the created deployment to see configuration details, and the status should say running:

Deployment is in Running state

Now we need to generate a token that will allow us to write data to our VictoriaMetrics Cloud instance. Go to the “Access” tab, type proxmox in the name box and set the token type to write, and click generate.

Generating Write Token

Then we will need to copy the hostname of your VictoriaMetrics Cloud instance, and the token you just generated.

Getting Hostname and Token

Please, do not share the generated access tokens with untrusted parties.

2. Configure Proxmox VE to send metrics to VictoriaMetrics Cloud #

Login as a root@PAM or user@pve with Administrator permissions to Proxmox VE:

Login to Proxmox Web UI

Click on Datacenter in the Proxmox UI, then click on Metric Server, click add, and click InfluxDB:

Adding new Metric Server on Proxmox PVE

Set parameters to match this screenshot replacing the Token with token you generated in step 1 and Server with the hostname mentioned in step 1:

Configure parameters for Metric Server

3. Confirm Data is Being Sent to VictoriaMetrics Cloud #

Go to your VictoriaMetrics Cloud deployment and click explore and run the following query system_uptime{object="nodes"}.

You should see 1 time series per ProxmoxVE node in your cluster.

4. View the Data in Grafana #

Before adding our VictoriaMetrics Cloud to Grafana we need a read only access token.

Go to the Access section of your VictoriaMetrics Cloud deployment, type grafana in the name box, set the Token Type to read, and click generate.

Generating Grafana Token

Click Show Examples on the token we just created and copy the values for Grafana

Getting credential for VictoriaMetrics Cloud

To add VictoriaMetrics Cloud as a datasource in Grafana, login to Grafana as an admin, click the hamburger menu in the top left of the screen, click Connections, then click Data sources, and click Add new data source.

On the next page select Prometheus as the datasource type.

Adding Connection in Grafana

To configure the datasource change the following options:

1. Set the Name to vm-dbaas
2. Set the Prometheus server URL to the Data Source URL shown in example above.

3. Expand the HTTP Headers section, click Add Header, set the value to Authorization and the value to the Header Value in the example above.

Setting Auth Header on Grafana Datasource

After changing these settings click save and test at the bottom. If You see a Green check mark saying Successfully queried the Prometheus API then everything is working.

To import a Proxmox dashboard click the hamburger menu in the upper left, click dashboards, click the blue button that says New on the right side of the screen, and press Import on the drop down:

Adding new dashboard to Grafana

Enter dashboard’s ID 16060 and press the Load button on the right:

Importing Proxmox dashboard

Choose vm-dbaas as a datasource and press the Import button.

Importing Proxmox dashboard

The expected result will resemble the following screenshot:

If this is what you see, then everything is working and you can observe the data on the dashboard!

5. Final thoughts #

• We have set up a deployment of VictoriaMetrics Cloud
• We have configured Proxmox VE to send metrics to VictoriaMetrics Cloud over HTTPS
• We have configured VictoriaMetrics Cloud as a datasource in Grafana
• We visualized resource usage in Proxmox VE via VictoriaMetrics Cloud and Grafana
