Select.Live Influx
A utility to read performance data from a Select.Live device and send to InfluxDB.
The end goal is to render performance data in Grafana, but the storage in InfluxDB is not specific to Grafana so may be useful in other cases.
The easiest way to have Grafana render the data appears to store it in InfluxDB and the easiest way to capture data from a SP Pro is to query the Select.Live device if one is already in place - so that's what this code does.
Grafana Example
Installing in Raspbian using Docker
This isn't best practice - it's just what I'm doing for now to get it running on a Raspberry Pi.
Install pre-requisists:
root@rasp:~# apt install git docker.io
Create a user that can run Docker:
root@rasp:~# useradd -m select-influx
root@rasp:~# usermod -aG docker select-influx
Clone the repo:
root@rasp:~# cd /opt
root@rasp:/opt#
root@rasp:/opt# git clone https://github.com/neerolyte/select-live-influx.git
Create a .env file:
root@rasp:/opt# cp ./select-live-influx/.env{.dist,}
Edit /opt/select-live-influx/.env to suit your installation.
Create a service file at /etc/systemd/system/select-live-influx.service with contents:
[Unit]
Description=Select live influx
After=network.target
[Service]
ExecStart=/opt/select-live-influx/scripts/docker node index.js
#ExecStart=/usr/bin/node index.js
WorkingDirectory=/opt/select-live-influx
StandardOutput=inherit
StandardError=inherit
Restart=always
User=select-influx
[Install]
WantedBy=multi-user.target
Ask systemd to enable and start the service:
root@rasp:~# systemctl reenable select-live-influx
Created symlink /etc/systemd/system/multi-user.target.wants/select-live-influx.service → /etc/systemd/system/select-live-influx.service.
root@rasp:~# systemctl restart select-live-influx
