An all-powerful toolset for Papel.
Sentinel is an autonomous agent for persisting, processing and automating Papel governance objects and tasks, and for expanded functions.
Sentinel is implemented as a Python application that binds to a local version 12 papeld instance on each Papel Masternode.
This guide covers installing Sentinel onto an existing 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
Clone the Sentinel repo and install Python dependencies.
$ git clone https://github.com/papelcoin/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
If you followed a guide where it had you install Papelcoin to the root directory your path to where you cloned sentiel will be:
* * * * * cd /root/sentinel && SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py >> sentinel.log 2>&1
Removed temporarily.
An alternative (non-default) path to the papel.conf file can be specified in sentinel.conf:
papel_conf=/path/to/papel.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
To view the debug output in real time enter:
tail -f sentinel.log
