The Idiot uses Grafana and Influxdb to monitor Proxmox

Custom and Configurable Data-visualization?  Yes, please.

Grafana is a data visualization tool that pulls in metrics from several data sources.  For our purposes, we’ll be using influxdb, which is a database that is geared towards time-based metrics.

For this instance, I’m using a template within Proxmox, specifically debian-9.0-standard_9.3-1_amd64.tar.gz on a 64-bit platform. However, so long as you have a modern-ish version of Debian, this guide should work just as well.  We’ll be using the CLI for the majority of our configurations, and assuming you’ve issued the superuser (su) to root.  If not, prefix your commands with “sudo”.

NOTE: I don’t go over securing this setup.  I plan on updating this guide with security enhancements.  Avoid using this in a production environment without adding security features!

Whenever starting a new system, always perform a quick update:
apt-get update && apt-get upgrade -y

Install influxdb
apt-get install influxdb

Edit your influxdb config file:
nano /etc/influxdb/influxdb.conf

Example: influxdb.conf udp snippet

Uncomment and edit the [udp] section to reflect the following:
enabled = true
bind-address = ""
database = "proxmox"
batch-size = 1000
batch-timeout = "1s"

NOTE: The database can be named anything, just make sure you remember what you called it when you add the data source in Grafana.  Also, the port can be anything you wish, just make sure it’s available on your network and matches your entry in the proxmox’s status.cfg later in the guide.

Look here for the latest release:

Use wget to download that file to your instance (we’ll be pulling the current version at the time: 5.0.1):

Use dpkg to install it:
dpkg -i grafana_5.0.1_amd64.deb

Edit server definitions on your pve node by creating the file “/etc/pve/status.cfg”.
nano /etc/pve/status.cfg

Add the following (make sure your port matches your entry in the influxdb.conf):
server your-server-ip-address
port 8089

Example: status.cfg snippet

Finally, start your services and make then run on boot:
service influxdb start
service grafana-server start
systemctl enable influxdb
systemctl enable grafana-server

Navigate to your instance’s http://your-server-ip-address:3000.  You should be presented with a login screen

Example: Grafana login screen

The default username and password for Grafana is admin:admin

Once you login, you’ll be asked to configure your data source:

Example: Grafana basic configuration for influxdb data source

Clicking “Save & Test” should confirm Grafana’s connection to Influxdb.

Example: confirmed connection to influxdb’s proxmox table

You should now be able to create graphs using the data pulled from Proxmox!  You can experiment with the data sets by creating a new dashboard and then adding a new panel.  I’ll give you an example of one of my “SingleStat” panel configurations; I use it to pull the CPU usage from a Proxmox host.
