What is capacity forecasting in BetterDB Monitor?
Capacity forecasting projects a time-to-ceiling estimate for memory, ops/sec, CPU, and fragmentation based on observed trends, rather than just showing you today's numbers on a dashboard.
Instead of discovering you're about to hit a memory limit only when Valkey starts evicting keys or refusing writes, teams get an early warning that lets them plan a scale-up, adjust a config, or clean up stale keys before the ceiling is actually reached.
This turns capacity planning from a reactive, post-incident exercise into something that shows up on a roadmap ahead of time, and it pairs naturally with anomaly detection: a sudden change in trend line is itself often the first sign something upstream has changed.
