# 1) rough focus astimation along full season-to-season
# focus range (as it was implemented in the old obs. script)
# 2) precise focussing along narrow range computed from
# previous rough estimation
# Next focussing runs compute range from the current focus value.

### Rotation of database files
The daemon keeps all DB files opened during its work, so for correct log rotation after renaming
all files (like `rename log log00 *.log`) you should send SIGUSR1 or SIGUSR2 to daemon, like
```bash
kill -USR1 $(cat /tmp/meteologger.pid)
```
After receiving of this signal daemon will open new DB files and you will be able to compress old
files.
### Examples ### Examples
1. Connect to a local daemon on port 5555 and store data in `/var/log/weather`: 1. Connect to a local daemon on port 5555 and store data in `/var/log/weather`:
