The `systemmonitor` sensor platform allows you to monitor disk usage,
|
||||
The System monitor integration allows you to monitor disk usage,
|
||||
memory usage, CPU usage, and running processes.
|
||||
|
||||
To add this platform to your installation,
|
||||
add the following to your `configuration.yaml` file:
|
||||
{% include integrations/config_flow.md %}
|
||||
|
||||
```yaml
|
||||
# Example configuration.yaml entry
|
||||
sensor:
|
||||
- platform: systemmonitor
|
||||
resources:
|
||||
- type: disk_use_percent
|
||||
arg: /config
|
||||
- type: memory_free
|
||||
```
|
||||
## Sensors
|
||||
|
||||
{% configuration %}
|
||||
resources:
|
||||
description: Contains all entries to display.
|
||||
required: true
|
||||
type: list
|
||||
keys:

arg:

||||
description: Argument to use, please check the table below for details.
|

|
||||
{% endconfiguration %}
|
||||
**All entities are disabled by default, you need to enable the entities that you wish to use.**
|
||||
|
||||
After restarting Home Assistant, these sensors will show up and update their
|
||||
information every 15 seconds.

|

|
||||
### 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
|
||||
|
||||
If no path is provided via the optional argument, the integration defaults to '/' (root).
|
||||
|
||||
**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
|
||||
@ -89,100 +70,8 @@ tmpfs 934M 0 934M 0% /dev/shm
|
||||
/dev/mmcblk0p1 253M 54M 199M 22% /boot
|
||||
```
|
||||
|
||||
Defining a `disk_use` sensor for `/` and `/home/pi` is redundant and will return the same values, since they both belong to the same "disk". However, defining separate sensors for `/dev` and `/dev/shm` is possible and provides different values, since those are treated as separate "disks" by the integration.
|
||||
|
||||
```yaml
|
||||
# Example configuration.yaml entry
|
||||
sensor:
|
||||
- platform: systemmonitor
|
||||
resources:
|
||||
- type: disk_use
|
||||
arg: /dev
|
||||
- type: disk_use
|
||||
arg: /dev/shm
|
||||
```
|
||||
|
||||
## 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 (even if the hardware sensor could provide that level of detail).
|
||||
|
||||
## Linux specific
|
||||
|
||||
To retrieve all available network interfaces on a Linux System, execute the
|
||||
`ifconfig` or `ip` command. The command differs based on your operation system and version.
|
||||
|
||||
```bash
|
||||
ifconfig -a | sed 's/[ \t].*//;/^$/d'
|
||||
```
|
||||
|
||||
```bash
|
||||
ip link show
|
||||
```
|
||||
|
||||
## Windows specific
|
||||
|
||||
When running this platform on Microsoft Windows, Typically,
|
||||
the default interface would be called `Local Area Connection`,
|
||||
so your configuration might look like:
|
||||
|
||||
```yaml
|
||||
sensor:
|
||||
- platform: systemmonitor
|
||||
resources:
|
||||
- type: network_in
|
||||
arg: "Local Area Connection"
|
||||
```
|
||||
|
||||
If you need to use some other interface, open a command line prompt and type `ipconfig` to list all interface names. For example a wireless connection output from `ipconfig` might look like:
|
||||
|
||||
```bash
|
||||
Wireless LAN adapter Wireless Network Connection:
|
||||
|
||||
Media State . . . . . . . . . . . : Media disconnected
|
||||
Connection-specific DNS Suffix . :
|
||||
```
|
||||
|
||||
Where the name is `Wireless Network Connection`.
|
||||
|
||||
## All available resources
|
||||
|
||||
```yaml
|
||||
# Example configuration.yaml entry with all entry types (delete/comment out as necessary)
|
||||
