I am setting up my own statistics for PiAware with Munin and I’m a little bit confused about the numbers in the PiAware-logfile.

```
>cat /tmp/piaware.out.yesterday | grep "Aircraft:"
01/02/2016 11:08:44 mlat(32156): Aircraft: 10 of 17 Mode S, 21 of 50 ADS-B used
01/02/2016 11:23:44 mlat(32156): Aircraft: 5 of 15 Mode S, 17 of 40 ADS-B used
01/02/2016 11:38:44 mlat(32156): Aircraft: 11 of 18 Mode S, 20 of 46 ADS-B used
01/02/2016 11:53:44 mlat(32156): Aircraft: 13 of 20 Mode S, 21 of 39 ADS-B used
01/02/2016 12:08:44 mlat(32156): Aircraft: 8 of 17 Mode S, 21 of 48 ADS-B used
01/02/2016 12:23:45 mlat(32156): Aircraft: 15 of 25 Mode S, 20 of 56 ADS-B used
01/02/2016 12:38:45 mlat(32156): Aircraft: 11 of 20 Mode S, 19 of 56 ADS-B used
```

Let’s take “Aircraft: 10 of 17 Mode S, 21 of 50 ADS-B used” as an example, what do these numbers mean? How many aircrafts did I “see”? 50? 67? What do 10 and 21 mean and what 17 and 50?

Thanks for help!

PS: Bonus karma for a way to get this data every 5 minutes, not 15. Is there a way?
