Running Grafana

1. Start Grafana server (grafana-server.exe). My installation is at C:\Program Files\GrafanaLabs\grafana\bin
2. Use web browser to go to http://localhost:3000/login
   • Default name and pwd is admin
3. Create a data source. Connections -> Data sources. Enter Infinity
   • However, the plugin needs to be installed first: grafana-cli plugins install yesoreyeram-infinity-datasource. The permission of the folders have to be changed. Perhaps should allow all. Then restart grafana.

Logs from Serial port

Use PuTTY and save (stream) logs to a file. Works like a charm. The notepad++ can be set to update automatically without asking (Ctrl-R reloads the file) by using Settings -> Preferences -> MISC. -> Update silently, but it still need Ctrl-R to reload the file.
