sf-monitoring-space extension extends heartbeat monitoring with disk space monitoring ability. Directories to monitor are discovered automatically:
- mysql/postgresql working directories
- typical directories that hold lots of data
Each monitored directory, if exists and is not a symlink, is required to have at least 12GB of free disk space on underlying filesystem.
- /boot partition is required to have at least 80MB free
- root filesystem is required to have at least 512MB free
