Are all those metrics you collect actually earning their keep? And what about alert rules—how many are silently broken, doomed never to fire?Monitoring nowadays is efficient enough to store billions of unique time series. But do all the series you store actually “pay the rent”? In this talk, Roman shows how to hunt down “ghost” metrics and “silent” alerts using the VictoriaMetrics ecosystem. You’ll learn:
How to spot time-series that no one has queried in months
Hints to find alerting rules that can never trigger
A repeatable workflow for pruning data without risking blind spots
Trim the noise, shrink your storage footprint, and reclaim performance—because the cheapest metric is the one you never write.
