HOWTO

1. Log in to AP

2. Generate SSH key

$ mkdir ~/.ssh
$ dropbearkey -t rsa -f ~/.ssh/id_dropbear -s 2048
ssh-rsa AAAA…== admin@apname

3. Add this key to server’s ~/.ssh/authorized_keys

Try a one-time upload by uploading ap-uploader.sh to the AP and running:

$ ./ap-uploader.sh user@server:path/

4. Set up regular data uploads

On the AP, run:

$ nohup sh -c 'while true; do ./ap-uploader.sh user@server:path/;sleep 600;done' &

Make sure files are being uploaded to the server every 10 minutes. If it all looks good then the AP setup is done. At least until it reboots.

5. On server: Create database

$ createdb ubntools
$ psql ubntools -f schema.sql

6. Import data

$ go build inserter.go
$ ./inserter -dbconnect='dbname=ubntools host=/var/run/postgresql sslmode=disable' /path/to/*.gz

7. Query data

$ psql ubntools
ubntools=> SELECT * FROM view_neighbors;
    ap    | channel |       bssid       |         essid          | bw | rssi | security | adhoc
----------+---------+-------------------+------------------------+----+------+----------+-------
  apname  |       6 | 00:8e:f2:aa:aa:aa | virginmediaxxxxxxx     | 20 |   10 | secured  | f
[…]

8. Generate channel utilization graph

$ go build mkgraph.go
$ ./mkgraph -dbconnect='dbname=ubntools host=/var/run/postgresql sslmode=disable' | gnuplot
$ mv foo.png /path/to/web/root/or/something/

Interesting queries

There are premade views (do \d and then SELECT * from view_…), but you can query more raw data too.

Current clients

SELECT
  essid,
  ap,
  channel,
  data->>'hostname' hostname,
  data->>'mac' mac,
  data->>'rssi' rssi
FROM sta_table_latest
ORDER BY essid,ap,channel,hostname,mac;

Active radios

SELECT
  ap,
  data->>'name' AS name,
  data->>'radio' AS radio,
  CASE data->>'is_11ac' WHEN 'true' THEN TRUE ELSE FALSE END as "802.11ac",
  data->>'max_txpower' AS power
FROM radio_table_latest
ORDER BY ap, name;

One client’s RSSI over time

SELECT
  ts,
  (data->>'rssi')::int rssi
FROM sta_table
WHERE data->>'mac'='11:22:33:44:55:66'
ORDER BY ts;

rssi of clients over time

SELECT
  ap,
  ts,
  essid,
  channel,
  data->>'hostname' hostname,
  data->>'mac' mac,
  data->>'rssi' rssi
FROM sta_table
ORDER BY data->>'mac',ts;

Show days when there was at least one DFS event forcing a change of channel

# SELECT TO_CHAR(ts,'YYYY-MM-DD') dayy,MIN(channel) channel FROM view_clients_history WHERE ap='ap-longrange' AND ts>'2020-11-01' AND channel>11 GROUP BY dayy ORDER BY dayy;
    dayy    | channel
