# Log volume estimator

Turn log lines per second and their size into daily and monthly volume, and see what dropping debug logs saves.

## How it works

Volume is lines per second, times seconds in a day, times the average line size, for every service.

```
daily = services × lines/s × 86,400 × line size
```

## Questions

### How big is a log line?

Plain text lines are often 150 to 400 bytes; JSON lines with context are often 500 bytes to 2 KB.

### Should I keep debug logs?

Rarely in production. Turn them on per service when you’re investigating.
