The System monitor integration allows you to monitor disk usage,
|
|
memory usage, CPU usage, and running processes.

## Sensors
|
|
|
|
**All entities are disabled by default, you need to enable the entities that you wish to use.**
|
|
|
|
### Disks
|
|
|
|
- Disk free - (One per disk/mount point)
|
|
- Disk use - (One per disk/mount point)
|
|
- Disk usage (percent) - (One per disk/mount point)
|
|
|
|
### Network
|
|
|
|
- IPv4 address - (One per network interface)
|
|
- IPv6 address - (One per network interface)
|
|
- Network in - (One per network interface)
|
|
- Network out - (One per network interface)
|
|
- Packets in - (One per network interface)
|
|
- Packets out - (One per network interface)
|
|
- Network throughput in - (One per network interface)
|
|
- Network throughput out - (One per network interface)
|
|
|
|

### Add `process` sensor
|
|
|
|
The `process` sensor needs to be configured by the config entry options. Go to **{% my integrations title="Settings > Devices & Services" %}**, select the **System Monitor** integration and click **Configure** to select which `process` sensors should be created.
|
|
|
|
## Disk usage
|
|
|
|
**Note:** The disk usage sensors do not support monitoring folder/directory sizes. Instead, it is only concerned with "disks" (more specifically mount points on Linux).
|
|
|
|
```bash
|
|
$ df -H
|
|
Filesystem Size Used Avail Use% Mounted on
|
|
/dev/root 29G 12G 16G 42% /
|
|
devtmpfs 805M 0 805M 0% /dev
|
|
tmpfs 934M 0 934M 0% /dev/shm
|
|
/dev/mmcblk0p1 253M 54M 199M 22% /boot
|
|
```
|
|
|
|
## Processor temperature
|
|
|
|
- If no hardware sensor data is available (e.g., because the integration runs in a virtualized environment), the sensor entity will not be created.
|
|
- The unit of measurement (Celsius vs. Fahrenheit) will be chosen based on the system configuration.
|
|
- Only the very first processor related hardware sensor is read, i.e. no individual core temperatures are available (even if the hardware sensor provides that level of detail).
