Dashboard Story: How We Created PMM Dashboard for Highload
Let’s say you have highload instances. How do you monitor them? There are a lot of servers with 100, 200… 500+ nodes. How can we collect, check, and analyze metrics from all these servers? How can we understand what and where something happened? Scroll, scroll, scroll… down? That was the task that we faced at Percona and successfully resolved.

Optimizing the Storage of Large Volumes of Metrics for a Long Time in VictoriaMetrics
Introduction Nowadays, the main tools for monitoring the operation of any application are metrics and logs. An important role is played by the time of their storage.

In the case, when the project is just starting, their volume is relatively small, but over time it becomes larger and larger and there is a need for optimization. In this article, I will touch upon the mechanisms for processing, storing and optimizing metrics during their long-term storage.
