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 Managed VictoriaMetrics and Grafana.

Monitoring, in the context of software, is a catch-all term for visibility into infrastructure, or an application. It can encompass metrics, logs, traces, and any other telemetry data that provides information on a running application, server, or another device. Monitoring helps you catch problems before your customers do and speeds up the time to resolution for any problems that do slip through. Managed monitoring is where another company runs part or all of your monitoring system.

Monitoring can get expensive due to the huge quantities of data that need to be processed. In this blog post, you’ll learn the best ways to store and process monitoring metrics to reduce your costs, and how VictoriaMetrics can help. This blog post will only cover open-source solutions. VictoriaMetrics is proudly open source. You’ll get the most out of this blog post if you are familiar with Prometheus, Thanos, Mimir or VictoriaMetrics.
