Quarian is a controller meant to shepherd Geth instances that are not performing properly, and alert/report on problems with a Geth instance. If Geth is not running properly, it will restart Geth with a command of your choosing.
Features:
- Remote node monitoring via JSON-RPC: Can monitor remote nodes and issue
HTTP requests to servers to cause geth restarts. Use the
http-restarteron your Geth client side to easily restart them with the correct command. - Easy to read logs: Nice easy UTF-8 + color logging output to stdout
- Multiple canonical sources for chain tip: Supports Etherscan, Etherchain, Infura, and your own geth nodes
- Modular checks: Checks are easy to write classes. Turn on and off specific checks.
Settings for Quarian are specified in settings.conf. Quarian will look here
for settings, as well as:
/etc/quarian/settings.conf/etc/quarian.conf/etc/default/quarian.conf/opt/quarian/settings.conf
in that order. The settings.conf file contains configuration information
for Quarian.
You will want to decide what checks to use for your system, and then add the
check modules you want Quarian to load as the checklist property, as a
comma-delimited string (e.g. cron,chaintip). If you want to write your own
checks for Quarian, see the README.md inside the quarian/checks folder.
Quarian is alpha software and is not yet an egg. Quarian is written for Python 3. Download and run:
pip3 install -r requirements.txt
./quarian.py
There are also some argument flags. You can see these by using quarian.py -h.
