Launch VictoriaMetrics
Configure remote write
Query from Grafana and vmui

Context. Your Prometheus only keeps 15 days of data. You add VictoriaMetrics as long-term storage, without changing how metrics are collected.

Prerequisites: Docker Compose · Estimated time: 35 min

Long-term storage in a few minutes.

Guided steps, with their solutions.

1. Write the Compose file
Why? Three services are enough: the database, Prometheus and Grafana, plus node-exporter so there is some data.
Create the Compose file and the Prometheus configuration.
2. Start and check
Why? VictoriaMetrics' internal metrics confirm that samples are arriving.
Start the stack and check the insert counter.
3. Query with vmui
Why? The built-in interface means you don't need to install anything for a first exploration.
Open http://localhost:8428/vmui and plot CPU usage by mode.
4. Connect Grafana
Why? As far as Grafana is concerned, VictoriaMetrics is a Prometheus data source.
Add a Prometheus data source pointing to http://vm:8428 and import a Node Exporter dashboard (for example ID 1860).
5. Measure disk usage
Why? Efficiency is the main selling point, so let's verify it.
Compare the number of stored samples with the disk space used.
