Simple code to send alerts if a heartbeat is not received.
The behaviour is hard-coded, to keep the code simple (no config validation needed).
- Install this repo contents in
/opt/stscor another location. - Install dependencies:
pip install -r requirements.txt. - Create a config file and edit it to set your credentials:
cp config-example.ini config.ini. Caution:.gitignoredoesn't seem to work - take care not to commit sensitive data.
Optional:
- Create a systemd unit.
cp stsc.service /etc/systemd/system. Edit the username and paths if required. systemctl daemon-reload;systemctl enable stsc.service;systemctl start stsc.service
The system to monitor should send a POST request to http://:64250/heartbeat every minute ( being the host on which this flask app is running).
It can send a request to http://:64250/explicit_alarm to trigger a generic alarm message (useful as a fallback alarm mechanism).
