Easier to install netdata on your host and pull the netdata data into hass:
2 Likes
Thanks @LarsNorgaard
I’ve installed Netadata into my Proxmox host and connected to HA via the example in the component page.
- platform: netdata
resources:
load:
data_group: system.load
element: load15
cpu:
data_group: system.cpu
element: system
Where can I find more data_group and elements to show in HA?
I, probably, understand that the data_group match what I see here in the Netdata dashboard
what about elements?
For example, I don’t see load15 here
Thanks

Where are you getting those information?
On which hardware are you on?
Thanks
I got the ideas from this HA forumand the system monitoring related setup came from this topic.
I use an Intel NUC 8GB RAM 120GB SSD and Ubuntu 18.04 with docker for the Hassio.

Almost my situation, I just have Proxmox as virtualizer.
Can you share how do you get all these info?
I’m interested in the temperature and wifi graph.
Thanks
What would you like to see, the card configuration or the sensor config?
- platform: command_line
name: CPU Temp
command: "cat /sys/class/thermal/thermal_zone2/temp"
unit_of_measurement: "°C"
value_template: '{{ value | multiply(0.001) | round(0) }}'

Would love to see your config for the graphs which show multiple entries (eg. downloads and uploads in one graph). Really like the way you have laid it out!
Here’s an example with 2 graphs
- accuracy: 5
align_icon: left
entities:
- entity: sensor.pi_hole_ads_blocked_today
name: Ads blocked
show_state: true
unit: ads
- entity: sensor.pi_hole_dns_queries_today
name: DNS queries
show_state: true
unit: queries
hours_to_show: 168
icon: 'mdi:pi-hole'
line_color: '#0073D4'
name: Pi-hole today
points_per_hour: 0.05
show:
points: false
type: 'custom:mini-graph-card'
I updated it based on some others here

Thanks a lot for that it really helps. How were you able to get the size of you database file?
This is my code:
- platform: sql
db_url: mysql://username:password-mariadb/homeassistant?charset=utf8
queries:
- name: HASS DB size
query: 'SELECT table_schema "database", Round(Sum(data_length + index_length) / 1048576, 2) "value" FROM information_schema.tables WHERE table_schema="homeassistant" GROUP BY table_schema;'
column: 'value'
unit_of_measurement: MB

Thanks, I was missing how to gather temp and network.
I created a cron job in my Proxmox instance to exec this tiny Python script that runs every 30 secs
cron job
* * * * * /root/systems_data.py
* * * * * (sleep 30 ; /root/systems_data.py )
systems_data.py
temp= "$(cat /sys/class/thermal/thermal_zone2/temp)"
cpuload= "$(grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage}')"
memavail= "$(cat /proc/meminfo | grep MemAvailable | awk '{print $2}')"
mosquitto_pub -h 192.xxx.xxx.xxx -u user -P password -t topic/temp -m $temp
mosquitto_pub -h 192.xxx.xxx.xxx -u user -P password -t topic/cpuload -m $cpuload
mosquitto_pub -h 192.xxx.xxx.xxx -u user -P password -t topic/memavail -m $memavail
In this way I can get those three values that I can show in my dashboard.
Hope it can help someone!

How did you install netdata on the host? I used the easy bash <(curl -Ss https://my-netdata.io/kickstart.sh)
But end up with some errors:
All required packages are already installed. Now proceed to the next step.
OK /bin/bash /tmp/netdata-kickstart-ws3vT4/install-required-packages.sh netdata
$'[\E[2m/tmp/netdata-kickstart-ws3vT4\E(B\E[0m]# \E[1m\E[33m' curl -sSL --connect-timeout 10 --retry 3 https://storage.googleapis.com/netdata-nightlies/sha256sums.txt $'\E(B\E[0m\\n' curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.

Hi @Dayve67
The installation I did was as explained here, the first option.
I have done it accessing SSH to the Proxmox server address, not the VM, and then executed the command without sudo.
That’s it!
But since the integration with HA is not so good, as far as I understood, I removed it.
My goal is to grab information and to show in HA using sensors, not to show just the Netdata Graph as is calling a http page.
That’s why I decided to go directly with a python script, as my previous message.
Here it is:

You are welcome and thanx!
I forgot the setup the maximum values… 
I think what you have done with card modder is the missing piece of the puzzle for making transparency work (not look terrible) with some of my stacked custom cards. I’ll give it a try. Thanks for sharing.
