Prometheus exporter for Cgminer (specifically Antminers)

Installation

Just execute the python script. Ensure that you have Python-Tornado installed

Usage

./cgminer_exporter.py

Configuration

You can define an environment variable to specify the number of threads: export THREADS=5

Service runs on port 9154

Testing can be done by loading /metrics?target=192.168.0.21

example:

curl hlocalhost:9154:/metrics?target=192.168.0.21

Prometheus configuration

Configuration Example

Setup the targets array with your miners, and set the replacement line to the host running the exporter:

- job_name: 'antminer'
    scrape_interval: 2s
    static_configs:
      - targets: ['192.168.0.21', '192.168.0.22', '192.168.0.23', '192.168.0.24']
    metrics_path: /metrics
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 192.168.0.190:9154

This setup allows Prometheus to provide scheduling and service discovery, as unlike all other exporters running an exporter on the machine from which we are getting the metrics from is not possible.
