Today, I learned about how Prometheus and Grafana work in tandem.
Prometheus is an application which we are using as a database (although can be used as standalone and has its own monitoring) that will collect any information from all systems on the server, while Grafana is a monitoring service that uses Prometheus to display the information.
Our team is doing a test set-up using a Proxmox Grafana community script (slowly build it for production). On one of our server’s nodes, we applied the script and set-up with advanced settings (main purpose is to up the cores to 4 because multiple people will be accessing the UI at peak hours).
Accessing the Grafana dashboard was successful, so we started to install Prometheus using the community script.
On the other nodes, we install the Prometheus Exporter using a script Garth created and edit the /etc/prometheus/prometheus.yml to add the docker nodes to be monitored.
Quick:
-
sudo tee -a /path/to/file >> /path/to/file << ‘EOF’ command command command EOF
-
systemctl daemon-reload is important for the .yml in /etc/ to run
-
systemctl restart prometheus.service
Research:
- systemd and systeminit
- dns srv record
