+# lego-monitoring
+
+DISCLAIMER: This repository does not have anything to do with the LEGO Group. "lego" is the internal name of my home server.
+
+## Prerequisites
+
+* `pacman -S libolm arch-audit`
+* `pip -r requirements.txt`
+
+## Configuring
+
+* Invite the bot account to the room (you have to accept the invite manually)
+* Copy `config.example.json` to `config.json`, edit as necessary
+* Run `alerting/login.py` once to login into Matrix
+* (optional) Create an `alerting` group and give `config.json`'s ownership and read rights to it, to allow sending alerts from less-privileged users
+
+### Setting up login alerts
+
+* Copy `lego-login-alert` to your `/etc/sudoers.d`
+* Add this to your `/etc/ssh/sshd_config`:
+```
+# login alerts
+ForceCommand /opt/lego-monitoring/wrappers/login_wrapper.sh
+```
+
+## Running
+
+* `prettyprint.py` -- check and print all sensors
+* `service.py` -- launch service
+* `assets/lego-monitoring.service` is a systemd unit that starts `service.py`
+
+### Disabling checks
+
+Put names of checks into config's `disabled_checks` to disable them. See `service.py` for check names.
