Chia Healthcheck

Chia Healthcheck is an application that is intended to run alongside a chia installation and return a simple healthy or unhealthy response for supported chia services.

Installation

Download the correct executable file from the release page and run. If you are on debian/ubuntu, you can install using the apt repo, documented below.

Apt Repo Installation

Set up the repository

1. Update the apt package index and install packages to allow apt to use a repository over HTTPS:

sudo apt-get update

sudo apt-get install ca-certificates curl gnupg

2. Add Chia's official GPG Key:

curl -sL https://repo.chia.net/FD39E6D3.pubkey.asc | sudo gpg --dearmor -o /usr/share/keyrings/chia.gpg

3. Use the following command to set up the stable repository.

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/chia.gpg] https://repo.chia.net/chia-healthcheck/debian/ stable main" | sudo tee /etc/apt/sources.list.d/chia-healthcheck.list > /dev/null

Install Chia Healthcheck

1. Update the apt package index and install the latest version of Chia Healthcheck

sudo apt-get update

sudo apt-get install chia-healthcheck

Usage

First, install chia-blockchain. Chia healthcheck expects to be run on the same machine as the chia blockchain installation, and will use either the default chia config (~/.chia/mainnet/) or else the config located at CHIA_ROOT, if the environment variable is set.

chia-healthcheck serve will start the healthcheck service on the default port of 9950.

You can check the status of the full node at <hostname>:9950/full_node. A response code 200 indicates the full node is receiving new blocks, while a response code of 500 would indicate that a new block has not been received within the healthcheck interval (5 minutes by default).

Configuration

Configuration options can be passed using command line flags, environment variables, or a configuration file, except for --config, which is a CLI flag only. For a complete listing of options, run chia-healthcheck --help.

To set a config value as an environment variable, prefix the name with CHIA_HEALTHCHECK_, convert all letters to uppercase, and replace any dashes with underscores (healthcheck-port becomes CHIA_HEALTHCHECK_HEALTHCHECK_PORT).

To use a config file, create a new yaml file and place any configuration options you want to specify in the file. The config file will be loaded by default from ~/.chia-healthcheck.yaml, but the location can be overridden with the --config flag.

healthcheck-port: 9950
