Selenium based grass (app.getgrass.io) miner.

• I recommend to use docker-compose
  • set environments in docker-compose.yaml first, and docker compose up -d

• The app.getgrass.io server might be unstable, causing the error. You can fix the problem by retrying to run the programme several times.

• Register with referal

• All environment variable values must be set.
• GRASS_USER
  • login id of app.grass.io
• GRASS_PASSWORD
  • login password of app.grass.io
• GRASS_CRX_NAME
  • extension crx file name in ./data
    • Example

    data
    └── grass-4.20.2.crx
    

    • GRASS_CRX_NAME=grass-4.20.2.crx
• GRASS_CRX_EXTENSION_ID
  • Grass chrome extension id
  • for example, 4.20.2 version extension id is
    • lkbnfiajjmbhnfledhphioinpickokdi
  • You could get details at chrome://extensions with developer mode

To support community node extension, this app needs crx file.

• get from app.getgrass.io
• direct link (4.20.2, Linux)
• You have to unzip the file.

$ curl -o ./data/grass.zip https://files.getgrass.io/file/grass-extension-upgrades/extension-latest/grass-community-node-linux-4.20.2.zip
$ cd ./data
$ unzip grass.zip -d .

The extension file must be located in ./data directory.

    • Gauge
  • grass_time_connected
    • Gauge
    • converted in minutes.
• /metrics

... some python metrics...

# TYPE grass_network_quality gauge
grass_network_quality{node_name="NODE_NAME"} 0.0
# HELP grass_node_earnings Grass node earnings metrics
# TYPE grass_node_earnings gauge
grass_node_earnings{node_name="NODE_NAME"} 0.0
# HELP grass_time_connected Grass node time connected metrics
# TYPE grass_time_connected gauge
grass_time_connected{node_name="NODE_NAME"} 0.0

• To get metrics in json, request GET /status
