This is a very simple OwnTracks Recorder replacement, which simply passes the data received to Prometheus. This can be later used to display the location in Grafana.
NOTE: This works perfectly well when your devices are always connected to the network. However, Prometheus will only accept data points at most 1 hour in the past. If your device was not connected for over 1 hour the data gathered will be lost. For this reason, I am abandoning this solution, at least until I figure out how to make Prometheus accept older data.
- HTTP server like nginx or Apache httpd
- uWSGI application server, with psgi plugin
- Prometheus
- Grafana
On Arch just use makepkg to compile, then install the resulting package.
makepkg
sudo pacman -U ...
Tell systemd to listen for incoming request on the unix socket:
sudo systemctl start uwsgi@owntracks-prometheus-relay.socket
Adjust nginx configuration to relay requests to the approptiate socket. E.g. in the server section add:
location /owntracks/ {
uwsgi_pass unix:/run/uwsgi/owntracks/prometheus/relay.sock;
include uwsgi_params;
}
Reload nginx configuration:
sudo systemctl reload nginx
Confirm that the application has started:
sudo systemctl status uwsgi@owntracks-prometheus-relay.service
If everything is correct, you should enable the socket permanently:
sudo systemctl enable uwsgi@owntracks-prometheus-relay.socket
An example grafana dashboard can be found in the examples directory.
