Are you using Supervisor to manage processes on a server? With supervisor-alert you can receive messages when the state of your processes change. Be the first to know when your services die!
With the default configuration supervisor-alert sends messages over Telegram. For this to work you need to install telegram-send system-wide first. You can also use any shell command to send the notifications.
Install supervisor-alert on your system:
sudo pip install supervisor-alert
You must install it with Python 2 because Supervisor doesn't support Python 3
yet. For Supervisor 4+ you may have Python 3 support, if
python3 -c 'import supervisor' doesn't give an error, you should install supervisor-alert with
sudo supervisor-alert --configure
for the default configuration. This will send notifications over Telegram. Read the next section to customize or if you dislike automatic configurations.
Create the file
/etc/supervisor/conf.d/supervisor_alert.conf as root:
[eventlistener:supervisor_alert] command=supervisor-alert --telegram events=PROCESS_STATE_RUNNING,PROCESS_STATE_EXITED,PROCESS_STATE_FATAL autostart=true autorestart=true stdout_logfile=NONE user=supervisor_alert
This will send the notifications over Telegram, to use something else, for example ntfy, pass in the command:
command=supervisor-alert -c 'ntfy send'
By default the config file at
/etc/telegram-send.conf is used for
telegram-send, to use a different config, or to pass any other options:
command=supervisor-alert -c 'telegram-send --config /home/user/bunny.conf'
Optionally you can show the hostname before each message with the
command=supervisor-alert --telegram --show-hostname
The default configuration will run the event listener as the user
supervisor_alert. It is a good practice to isolate services by running them as
separate users (and avoiding running them as root). Add the user with:
sudo adduser supervisor_alert --system --no-create-home
Optionally, you can also subscribe to different supervisor events, look at the docs to see on which ones you'd like to be notified.
Finally, load the config and start the event listener:
sudo supervisorctl reread sudo supervisorctl update
You should now receive your first alert, notifying you that
has started running.
