Netdata is a [very efficient](https://github.com/netdata/netdata/blob/master/docs/guides/configure/performance.md)
|
|
server performance monitoring solution. When running in server hardware, it can collect
|
|
thousands of system and application metrics **per second** with just 1% CPU utilization of a single core. Its web server
|
|
responds to most data requests in about **half a millisecond** making its web dashboards spontaneous, amazingly fast!
|
|
|
|
Netdata can also be a very efficient real-time monitoring solution for **IoT devices** (RPIs, routers, media players,
|
|
wifi access points, industrial controllers and sensors of all kinds). Netdata will generally run everywhere a Linux
|
|
kernel runs (and it is glibc and [musl-libc](https://www.musl-libc.org/) friendly).
|
|
|
|
You can use it as both a data collection agent (where you pull data using its API), for embedding its charts on other
|
|
web pages / consoles, but also for accessing it directly with your browser to view its dashboard.
|
|
|
|
The Netdata web API already provides **reduce** functions allowing it to report **average** and **max** for any
|
|
timeframe. It can also respond in many formats including JSON, JSONP, CSV, HTML. Its API is also a **google charts**
|
|
provider so it can directly be used by google sheets, google charts, google widgets.

|
|
|
|
Although Netdata has been significantly optimized to lower the CPU and RAM resources it consumes, the plethora of data
|
|
collection plugins may be inappropriate for weak IoT devices. Please follow
|
|
the [Netdata Agent performance guide](https://github.com/netdata/netdata/blob/master/docs/guides/configure/performance.md)
|
|
|
|
## Monitoring RPi temperature
|
|
|
|
The python version of the sensors plugin uses `lm-sensors`. Unfortunately the temperature reading of RPi are not
|
|
supported by `lm-sensors`.
|
|
|
|
Netdata also has a bash version of the sensors plugin that can read RPi temperatures. It is disabled by default to avoid
|
|
the conflicts with the python version.
|
|
|
|
To enable it, run:
|
|
|
|
```bash
|
|
cd /etc/netdata # Replace this path with your Netdata config directory
|
|
sudo ./edit-config charts.d.conf
|
|
```
|
|
|
|
and uncomment this line:
|
|
|
|
```sh
|
|
sensors=force
|
|
```
|
|
|
|
Then restart Netdata. You will get this:
