prometheus-chia-exporter

Prometheus exporter for several chia node statistics It's assumed that the full node, the harvester and the wallet run on the same system.

Requirements

The exporter is meant to be run from your chia-blockchain venv. Additionally you need prometheus-client as specified in requirements.txt

cd chia-blockchain
. ./activate
cd ../prometheus-chia-exporter
pip install -r requirements.txt

Grafana

The provided dashboard does use features which are only available in the latest (7.5.5) version of grafana.
Please make sure you are using this or a newer version.

You can still decide to use an older version but then the farmer_address and pool_address display does not work correct.

Installation

Copy the needed files to their locations as described below

# Copy the systemd unit file
sudo cp systemd/chia_exporter.service /etc/systemd/system
# Edit the unit file to have correct chia blockchain path and username
# Copy the environment file
sudo cp systemd/chia_exporter.env /etc/default/
# If the node you want to monitor does not run on the same host as the exporter, edit the env file
# copy the exporter to /usr/local/bin/
sudo cp prometheus-chia-exporter/chia-exporter.py /usr/local/bin/
# Reload systemd to have access to the new service
sudo systemctl daemon-reload
# Make sure the service is started on system boot
sudo systemctl enable chia_exporter
# Start the service
sudo systemctl start chia_exporter

Custom config

You can monitor remote nodes by editing /etc/default/chia_exporter.env and changing the settings there

Usage

Start the systemd service
Import grafana/dashboard.json to your grafana
The exporter will listen on port 9824
Add prometheus config

scrape_configs:
  - job_name: 'chia'
    static_configs:
      - targets: ['nodeip:9824']

Overriding hostnames

If you are running the full node on a different host or container, you can override the hostnames used for connecting to the daemons by setting one or all of the following environment variables: FULL_NODE_HOST, WALLET_HOST, HARVESTER_HOST, FARMER_HOST. All hostnames default to localhost.
