An all-powerful toolset for Nyx.
Sentinel is an autonomous agent for persisting, processing and automating Nyx V12.1 governance objects and tasks, and for expanded functions in the upcoming Nyx V13 release (Evolution).
Sentinel is implemented as a Python application that binds to a local version 12.1 nyxd instance on each Nyx V12.1 Masternode.
This guide covers installing Sentinel onto an existing 12.1 Masternode in Ubuntu 14.04 / 16.04.
Make sure Python version 2.7.x or above is installed:
python --version
Update system packages and ensure virtualenv is installed:
$ sudo apt-get update
$ sudo apt-get -y install python-virtualenv
Make sure the local Nyx daemon running is at least version 12.1 (120100)
$ nyx-cli getinfo | grep version
Clone the Sentinel repo and install Python dependencies.
$ git clone https://github.com/nyxpay/sentinel.git && cd sentinel
$ virtualenv ./venv
$ ./venv/bin/pip install -r requirements.txt
Set up a crontab entry to call Sentinel every minute:
$ crontab -e
In the crontab editor, add the lines below, replacing '/home/YOURUSERNAME/sentinel' to the path where you cloned sentinel to:
* * * * * cd /home/YOURUSERNAME/sentinel && ./venv/bin/python bin/sentinel.py >/dev/null 2>&1
An alternative (non-default) path to the nyx.conf file can be specified in sentinel.conf:
nyx_conf=/path/to/nyx.conf
To view debug output, set the SENTINEL_DEBUG environment variable to anything non-zero, then run the script manually:
$ SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py
